}}<br />
The '''Tektronix 1S1''' is a [[sampling oscilloscope|sampling]] plug-in for [[500-series scopes]]. <br />
<br />
It is essentially one channel of a sampling unit and a timing unit from a [[661]]. It has its own trigger and timebase. <br />
<br />
The oscilloscope's timebase is usually set to a relatively slow sweep rate when using a 1S1. Alternatively, the sweep on the oscilloscope can be free-run, <br />
and the horizontal voltage from the oscilloscope can be used to control the 1S1, as described below. <br />
<br />
The 1S1 has a 50 Ω [[GR-874 connector]] for signal input. The plug-in supplies power (+100 V and -12.6 V) to accessories like the [[P6032]] Cathode Follower Probe, the [[281]] TDR Pulser, and the [[282]] Probe Adapter. <br />
<br />
The 1S1 can operate in normal self-swept mode or an external sweep signal can be applied to the 1S1. <br />
With the 1S1's internal sweep disabled, the horizontal-in and vertical-out connections can be used <br />
so the the 1S1 acts as a lookup table, a mapping of x to y, a function. <br />
The 661 also has this capability, in its "A vert/B horiz" mode, which is like X-Y mode for a sampler. <br />
In this mode, the horizontal-in voltage controls the time after the trigger event when the sample should be taken, <br />
and the vertical-out voltage corresponds to the voltage measured at that instant. <br />
This allows a waveform to be digitized using an arbitrarily slow DAC to generate the horizontal voltage <br />
and ADC to read the sampled output. But perhaps more importantly, by setting a constant horizontal-in voltage, <br />
it allows the output signal at one equivalent time instant to be processed in the time domain. <br />
For example, this allows the voltage to be low-pass filtered, so that it can be more accurately measured. <br />
The other reason why one might want a signal that consists of multiple sequential measurements <br />
of the same equivalent-time instant is that statistics can be calculated on these observations. <br />
For example, one might want to know, when testing a logic gate, what is the propagation delay <br />
such that 99.9% of the transitions happen faster than this. <br />
<br />
The horizontal-in voltage can also be produced, in "manual" mode, by setting a knob on the 1S1.<br />
<br />
The sampler in the 1S1 is quite different from the sampler in the [[1S2]]. The 1S1 uses a [[sampling diodes|four-diode]] sampling bridge, terminated within the 1S1. The 1S2 uses a two-diode feed-through sampler, typical for TDR instruments.<br />
<br />
Type 1S1 was designed by [[Chuck Edgar]], [[introduced in 1965]] and sold through 1973.<br />
<br />
The Type [[282]] Probe Adapter works with the 1S1. <br />
It is an active buffer to allow the use of high impedance probes with the 50 ohm input of the 1S1. <br />
It does, however, lower the bandwidth.<br />
<br />
When the 1S1 is set for INT trigger signal, the EXT TRIG input is terminated with 50 ohms.<br />

}}<br />
The '''Tektronix 1S1''' is a [[sampling oscilloscope|sampling]] plug-in for [[500-series scopes]]. <br />
<br />
It is essentially one channel of a sampling unit and a timing unit from a [[661]]. It has its own trigger and timebase. <br />
<br />
The oscilloscope's timebase is usually set to a relatively slow sweep rate when using a 1S1. Alternatively, the sweep on the oscilloscope can be free-run, <br />
and the horizontal voltage from the oscilloscope can be used to control the 1S1, as described below. <br />
<br />
The 1S1 has a 50 Ω [[GR-874 connector]] for signal input. The plug-in supplies power (+100 V and -12.6 V) to accessories like the [[P6032]] Cathode Follower Probe and the [[281]] TDR Pulser. <br />
<br />
The 1S1 can operate in normal self-swept mode or an external sweep signal can be applied to the 1S1. <br />
With the 1S1's internal sweep disabled, the horizontal-in and vertical-out connections can be used <br />
so the the 1S1 acts as a lookup table, a mapping of x to y, a function. <br />
The 661 also has this capability, in its "A vert/B horiz" mode, which is like X-Y mode for a sampler. <br />
In this mode, the horizontal-in voltage controls the time after the trigger event when the sample should be taken, <br />
and the vertical-out voltage corresponds to the voltage measured at that instant. <br />
This allows a waveform to be digitized using an arbitrarily slow DAC to generate the horizontal voltage <br />
and ADC to read the sampled output. But perhaps more importantly, by setting a constant horizontal-in voltage, <br />
it allows the output signal at one equivalent time instant to be processed in the time domain. <br />
For example, this allows the voltage to be low-pass filtered, so that it can be more accurately measured. <br />
The other reason why one might want a signal that consists of multiple sequential measurements <br />
of the same equivalent-time instant is that statistics can be calculated on these observations. <br />
For example, one might want to know, when testing a logic gate, what is the propagation delay <br />
such that 99.9% of the transitions happen faster than this. <br />
<br />
The horizontal-in voltage can also be produced, in "manual" mode, by setting a knob on the 1S1.<br />
<br />
The sampler in the 1S1 is quite different from the sampler in the [[1S2]]. The 1S1 uses a [[sampling diodes|four-diode]] sampling bridge, terminated within the 1S1. The 1S2 uses a two-diode feed-through sampler, typical for TDR instruments.<br />
<br />
Type 1S1 was designed by [[Chuck Edgar]], [[introduced in 1965]] and sold through 1973.<br />
<br />
The Type [[282]] Probe Adapter works with the 1S1. <br />
It is an active buffer to allow the use of high impedance probes with the 50 ohm input of the 1S1. <br />
It does, however, lower the bandwidth.<br />
<br />
When the 1S1 is set for INT trigger signal, the EXT TRIG input is terminated with 50 ohms.<br />

The '''Tektronix Type G''' is a plug-in differential amplifier for [[500-series scopes]].<br />
<br />
Unlike the [[D|Type D]], the Type G is optimized for RF, achieving only a 100 to 1 common-mode<br />
rejection ratio but operating all the way to 20 MHz. <br />
Unlike "comparator" plug-ins such as the [[W|Type W]] and [[Z|Type Z]], <br />
the Type G does not contain an internal precision variable voltage source. <br />
It is for measuring the difference between two externally applied input signals. <br />
Its maximum sensitivity is 50 mV/div. It has seven tubes.<br />
<br />
Its name changed twice. Type 53G was [[introduced in 1955|introduced in March 1955]] along with the<br />
[[541]]/[[545]], but it was only specified to 10 MHz in a [[535]], and its<br />
performance in a fast mainframe was not documented. When the mainframe cabinet styles<br />
were revamped in August 1956, the Types 53[[A]], 53[[B]], 53[[C]] and 53G were<br />
all upgraded (sped up) and renamed; Type 53G became Type 53/54G. It was the only<br />
early plug-in that did not go through the awkward "53x/54x" phase.<br />
In 1959 it became Type G with no further change in design. It was dropped after 1970.<br />
<br />
[[K]], [[L]], and [[T]] are tied for longest production life, at 16 years.<br />
[[B]], [[D]], and [[G]] are next at 15 years.<br />
<br />
Types G and [[K]] are the only letter-series plugins<br />
where the Gain vernier is not concentric with the step attenuator.<br />

The '''Tektronix Type D''' is a differential amplifier plug-in for [[500-series scopes]].<br />
<br />
It has high gain, and the bandwidth depends on the gain, ranging from 2 MHz at 50 mV/div and up, to 300 kHz at 1 mV/div.<br />
<br />
It displays the difference between two input signals, with a common-mode rejection ratio of 10,000. It has<br />
six tubes, on a shock-mounted subchassis to avoid microphonics.<br />
<br />
Type D was [[introduced in 1954|introduced]] with the [[531]] and [[535]] in [[introduced in 1954|1954]] as Type 53D,<br />
was briefly renamed Type 53D/54D in 1955 with the introduction of the [[541]] and [[545]], then quickly renamed Type 53/54D,<br />
then shortened to Type D in 1959 with the introduction of the 5xxA scopes. Its last year was 1968, having been superseded <br />
by the constant-bandwidth model [[1A6]].<br />
<br />
[[K]], [[L]], and [[T]] are tied for longest production life, at 16 years.<br />
[[B]], [[D]], and [[G]] are next at 15 years.<br />
<br />
[[Lavoie Laboratories]] produced an unauthorized clone, the [[Lavoie LA-265-D]].<br />
<br />
==Internals==<br />
Some production runs used a pair of [[5814]] tubes at the input while others used [[12AU7]]'s.<br />
These two tube types have different heater currents, and because the heaters are<br />
series-wired, you cannot switch from one type to the other without circuit modification.<br />

It is identical to [[A|Type A]], with the addition of a 10x-gain<br />
AC amplifier which can be switched in to extend the vertical<br />
sensitivity from 50 mV/div to 5 mV/div.<br />
<br />
Like the Type A, the Type B has its roots in the [[introduced in 1954|1954]]<br />
introduction of the [[531]] and [[535]], as the Type 53B,<br />
with 10x-AC bandwidth of 2 Hz to 9 MHz.<br />

In 1956, it was replaced by the Type 53/54B with DC-20 MHz<br />
or 2 Hz-12 MHz bandwidth in the [[541]] and [[545]]. <br />

In 1959, the Type 53/54B was renamed the Type B, <br />

The Tektronix Type T is a timebase plug-in primarily intended for use in the [[536]] X-Y scope. It<br />
contains trigger and sweep circuitry. The typical use of a Type T plug-in is as the X-axis plug-in <br />
in a 536. This configuration makes the 536 behave like a normal oscilloscope instead of an X-Y scope. However, there is no capability for internal triggering. A jumper must be connected from the Vertical Signal Out on the 536 to the External Trig on the T. <br />
<br />
If you put a Type T in a vertical slot of a normal [[500-series scopes|500-series scope]], <br />
you can make a raster, and using the scope's Z-axis input this allows a crude video display.<br />
<br />
The banana jack on the back of the plugin is to provide retrace blanking when used in the horizontal slot of a [[536]]<br />

The '''Tektronix Type L''' is an amplifier plug-in for [[500-series scopes]].<br />
<br />
The Type L is a [[K|Type K]] plus a 10x-gain AC-coupled preamp<br />
that extends the maximum sensitivity to 5 mV/div.<br />
Bandwidth in a [[545]] is 30 MHz at 50 mV/div and above, 3 Hz-24 MHz at 20 mV/div and below.<br />
<br />
Type 53/54L was [[introduced in 1957]] along with the [[536]] and its companion<br />
[[T|53/54T]] sweep plug-in. It was renamed the Type L in 1959.<br />
It was the fastest 5 mV plug-in until the [[1A1]] in 1964.<br />
It was dropped after 1972.<br />
<br />
[[K]], [[L]], and [[T]] are tied for longest production life, at 16 years.<br />
[[B]], [[D]], and [[G]] are next at 15 years.<br />
<br />
Late versions have a [[BNC connector]] instead of a [[UHF connector]].<br />
<br />
[[Lavoie Laboratories]] produced an unauthorized clone, the [[Lavoie LA-265-L|LA-265-L]].<br />

The '''Tektronix Type K''' is a plug-in for [[500-series scopes]].<br />
<br />
Max sensitivity is 50 mV/div, and bandwidth in a [[545]] is 30 MHz.<br />
<br />
Type 53K/54K was [[introduced in 1955|introduced in March 1955]] along with the [[541]]/[[545]].<br />
At that time, it was the only plug-in that could utilize the<br />
new mainframes' speed; the redesigned [[A|Type A]], [[B|Type B]], and [[C|Type C]]<br />
weren't ready until August 1956. In August 1955, just five months<br />
after introduction, it was renamed Type 53/54K, and, in 1959,<br />
when the 541A/545A mainframes came out, it got its final name, Type K.<br />
It was dropped after 1970, with [[L|Type L]] replacing it.<br />
<br />
[[K]], [[L]], and [[T]] are tied for longest production life, at 16 years.<br />
[[B]], [[D]], and [[G]] are next at 15 years.<br />
<br />
Type K was the fastest of the single-channel plug-ins.<br />
Tek did not equal it until [[L|Type L]] in 1957,<br />
and did not exceed it until [[1A1|Type 1A1]] in 1964.<br />
<br />
Earlier single-channel plug-ins had two inputs and a<br />
switch to select between them, making it convenient<br />
to probe two test points at once. The Type K design<br />
could not tolerate the extra stray capacitance,<br />
and the feature was dropped, never to return.<br />
<br />
The name was deliberately chosen to be halfway into the alphabet. Slow<br />
plug-ins would use A-J and fast ones L-Z. This idea never went anywhere.<br />
<br />
Late versions had a [[BNC connector]] instead of a [[UHF connector]].<br />
<br />
Types [[K]] and [[G]] are the only letter-series plug-ins<br />
where the Gain vernier is not concentric with the step attenuator.<br />

The '''Tektronix Type N''' is a [[sampling_oscilloscope|sampling]] plug-in for [[500-series scopes]]. It was the first sampler produced by Tektronix. <br />
Its risetime is specified to be under 600 picoseconds. <br />
<br />
Type N was [[introduced in 1960]], superseded by the [[661|Type 661]] Sampling Oscilloscope system a year later,<br />
and discontinued in 1964.<br />
<br />
Type N is a complete sampling subsystem, using the 500-series oscilloscope just as a power supply and a display. The oscilloscope is <br />
operated in X-Y mode and gets its horizontal signal from the Type N plug-in instead of from the scope's sweep circuitry. The input signal<br />
is applied through a 50 Ω [[GR-874 connector]].<br />
<br />
The sampling circuit of the Type N is primitive. It uses a single diode, the "interrogate diode", D5480. The strobe pulse is added to the <br />
input signal using a passive summing circuit. Consequently, the amplitude of the kick-out pulse from the input is high, about 150 mV.<br />
<br />
The vertical scale of the Type N is fixed at 10 mV/cm, making Type N one of the few Tektronix plug-ins with fixed vertical gain. In practice, <br />
attenuators can be placed in the signal path, external to the Type N, to achieve the desired sensitivity. Using an input attenuator also has <br />
the effect of attenuating the kick-out pulse seen by the device under test. <br />
<br />
According to Stefan Graef (http://www.messmuseum.de/tek661.htm),<br />
<blockquote><br />
The engineer behind the N was [[Norm Winningstad]]. He worked at Hughes Aircraft Electronics Division and was offered a job at HP's <br />
oscilloscope division to join their Sampling Scope team. After getting informed about the work he went to Tektronix developing the N <br />
(according to: "A narrative history of Hewlett-Packard from 1939-1990" by John Minck)<br />
</blockquote><br />
<br />
For calibration of the timebase of the Type N, the [[013-028|013-028 Timing Standard]] was produced.<br />

The '''Tektronix Type O''' is a [[letter-series and 1-series plug-ins|letter-series plug-in]] that contains two op-amps. <br />
<br />
The input and feedback networks of the op-amps can be configured from the front panel using knobs and/or user-supplied components.<br />
There are sockets on the front panel for banana plugs. <br />
<br />
Type O also has a regular signal input that does not involve the op-amps. <br />
A mode switch selects which op-amp's output will be displayed, or the regular signal input.<br />
<br />
Regular signal bandwidth is 25 MHz, maximum sensitivity is 50 mV/div,<br />
op-amp gain-bandwidth product is 15 MHz, and open-loop DC gain is 2500.<br />
<br />
Type O was [[introduced in 1962|introduced in mid-1962]] and was<br />
available through 1973.<br />
<br />
The Type O can be used with any of the following adapters: <br />
[[013-081]], [[013-068]], [[013-048]], [[013-0048-01]], [[013-0049-01]], [[013-0086-00]], [[013-0067-00]] (manual below).<br />

The '''Tektronix Type 541''' is a 30 MHz* oscilloscope that accepts [[letter-series and 1-series plug-ins]].<br />
It has a [[distributed amplifier]] and is exactly like the Type [[545]] <br />
except it does not have the Delayed Sweep (dual timebase) feature.<br />
<br />
It was [[introduced in 1955]] simultaneously with the 545, <br />
and was superseded in [[introduced_in_1959|1959]] by the 541A,<br />
which has more convenient controls.<br />
For example, the 541 required the operator to set two rotary switches to get<br />
the desired sweep time/div .<br />
The 541A replaced the two-switch design with a many-position rotary switch.<br />
This was also the case with setting the calibrator amplitude, <br />
which involved two switches on the 541 and one switch on the 541A.<br />
<br />
The 541's CRT is part number [[154-098]], also known as the T54. <br />
The standard [[phosphor]] is P2. The 541A uses the [[T65]] CRT.<br />
<br />
There is a rackmount version, Type RM41.<br />
<br />
There is also a 541-S7 version, which has single-sweep mode.<br />
<br />
A new probe, the [[P410|P400 Series]], was created for the 541/545, because the 10MHz [[P510|P510A]] rings on fast signals.<br />

The "P400 Series" (not to be confused with the modern [[P400]] probe) also includes P405 (5x), P420 (20x), P450 (50x), P450-L (50x extra low capacitance), and P4100 (100x).<br />
<br />
These probes were [[Introduced in 1955]] along with the [[541|Type 541]] and [[545|Type 545]] scopes because at 30MHz the [[P510|P510A]]'s 50-ohm coax cable exhibited unacceptable ringing due to the impedance mismatch at the scope's 1 MΩ input. It uses a special cable with a very thin, high-resistance center conductor which creates a better impedance match. All subsequent high-impedance probes use this kind of cable.<br />

The '''Tektronix Type K''' is a plug-in for [[500-series scopes]].<br />
<br />
Max sensitivity is 50 mV/div, and bandwidth in a [[545]] is 30 MHz.<br />
<br />
Type 53K/54K was [[introduced in 1955|introduced in March 1955]] along with the [[541]]/[[545]].<br />
At that time, it was the only plug-in that could utilize the<br />
new mainframes' speed; the redesigned [[A|Type A]], [[B|Type B]], and [[C|Type C]]<br />
weren't ready until August 1956. In August 1955, just five months<br />
after introduction, it was renamed Type 53/54K, and, in 1959,<br />
when the 541A/545A mainframes came out, it got its final name, Type K.<br />
It was dropped after 1970, with [[L|Type L]] replacing it.<br />
<br />
Type K was the fastest of the single-channel plug-ins.<br />
Tek did not equal it until [[L|Type L]] in 1957,<br />
and did not exceed it until [[1A1|Type 1A1]] in 1964.<br />
<br />
Earlier single-channel plug-ins had two inputs and a<br />
switch to select between them, making it convenient<br />
to probe two test points at once. The Type K design<br />
could not tolerate the extra stray capacitance,<br />
and the feature was dropped, never to return.<br />
<br />
The name was deliberately chosen to be halfway into the alphabet. Slow<br />
plug-ins would use A-J and fast ones L-Z. This idea never went anywhere.<br />
<br />
Late versions had a [[BNC connector]] instead of a [[UHF connector]].<br />
<br />
Types [[K]] and [[G]] are the only letter-series plug-ins<br />
where the Gain vernier is not concentric with the step attenuator.<br />

The '''Tektronix Type W''' is a differential comparator plug-in amplifier for [[500-series scopes]]. <br />
Its bandwidth varies from 23 MHz to 8 MHz depending on gain. Only modestly <br />
faster than its [[Z|Type Z]] predecessor, Type W extends performance in <br />
terms of sensitivity, reaching 1 mV/div. <br />
<br />
It achieves 20,000 to 1 common-mode rejection at DC and low frequencies.<br />
It has a built in precision variable voltage supply, "V<sub>c</sub>", <br />
which is controlled by a ten-turn pot and can vary from either -1.1 V to +1.1 V or -11 V to +11 V. <br />
<br />
Type W has two signal inputs, "A" and "B". <br />
A mode switch selects between displaying A-Vc, A-B, or Vc-B. <br />
The "A-B" mode is particularly useful for displaying the current in a sense resistor, <br />
while the other modes provide "slideback" measurements of small variations superimposed on a large constant. <br />
<br />
An output of V<sub>c</sub> is provided on the front panel of the Type W. Unlike the Z,<br />
Type W has two gain axes, a decade attenuator and a 1-2-5-10-20-50 selector, <br />
reminiscent of [[D|Type D]] from ten years before.<br />
<br />
Type W is the only letter-series plug-in with an "infinite resistance" input mode selectable at the front panel.<br />
([[1A5|Type 1A5]] has an internal jumper that can be cut.)<br />
<br />
In the letter-series timeline of differential comparators, Type W, [[introduced in 1965]], <br />
follows [[Z|Type Z]] and precedes [[1A5|Type 1A5]].<br />

The '''Tektronix Type E''' is a low-level differential amplifier plug-in for [[500-series scopes]].<br />
The sensitivity ranges from 50 μV/div to 10 mV/div. The input is an [[XLR connector]] feeding <br />
directly into the grids of a [[12AX7]] differential amplifier. <br />
<br />
Despite the DC-coupled input stage, the Type E is an AC-coupled amplifier.<br />
It has front panel knobs for selecting the low-frequency and high-frequency cutoff.<br />
It achieves a 50,000 to 1 common mode rejection ratio. Maximum bandwidth is 60 kHz.<br />
It has seven tubes on a shock-mounted subchassis.<br />
<br />
The Type 53E/54E was [[introduced in 1955]]. <br />
Along with Types [[G]] and [[K]], it was the first plug-in offered after, not during, <br />
the original [[531]]/[[535]] introduction in 1954.<br />
The nomenclature was revised after just a few months, to 53/54E. <br />
In 1959, when the A-suffix mainframes came out, all plugins dropped the "53/54". <br />
Type E was dropped after 1968; its replacement, [[1A7|Type 1A7]], had been available for a few years.<br />

The '''Tektronix Type E''' is a low-level differential amplifier plug-in for [[500-series scopes]].<br />
The sensitivity ranges from 50 μV/div to 10 mV/div. The input is an [[XLR connector]] feeding <br />
directly into the grids of a [[12AX7]] differential amplifier. <br />
<br />
Despite the DC-coupled input stage, the Type E is an AC-coupled amplifier.<br />
It has front panel knobs for selecting the low-frequency and high-frequency cutoff.<br />
It achieves a 50,000 to 1 common mode rejection ratio. Maximum bandwidth is 60 kHz.<br />
It has seven tubes on a shock-mounted subchassis.<br />
<br />
The Type 53E/54E was [[introduced in 1955]]. <br />
Along with Types [[G]] and [[K]], it was the first plug-in offered after, not during, <br />
the original [[531]]/[[535]] introduction in 1954.<br />
The nomenclature was revised after just a few months, to 53/54E. <br />
In 1959, when the A-suffix mainframes came out, all plugins dropped the "53/54". <br />
Type E was dropped after 1968; its replacement, [[1A7|Type 1A7]] had been available for a few years.<br />

The '''Tektronix Type K''' is a plug-in for [[500-series scopes]].<br />
<br />
Max sensitivity is 50 mV/div, and bandwidth in a [[545]] is 30 MHz.<br />
<br />
Type 53K/54K was [[introduced in 1955|introduced in March 1955]] along with the [[541]]/[[545]].<br />
At that time, it was the only plug-in that could utilize the<br />
new mainframes' speed; the redesigned [[A|Type A]], [[B|Type B]], and [[C|Type C]]<br />
weren't ready until August 1956. In August 1955, just five months<br />
after introduction, it was renamed Type 53/54K, and, in 1959,<br />
when the 541A/545A mainframes came out, it got its final name, Type K.<br />
It was dropped after 1970.<br />
<br />
Type K was the fastest of the single-channel plug-ins.<br />
Tek did not equal it until [[L|Type L]] in 1957,<br />
and did not exceed it until [[1A1|Type 1A1]] in 1964.<br />
<br />
Earlier single-channel plug-ins had two inputs and a<br />
switch to select between them, making it convenient<br />
to probe two test points at once. The Type K design<br />
could not tolerate the extra stray capacitance,<br />
and the feature was dropped, never to return.<br />
<br />
The name was deliberately chosen to be halfway into the alphabet. Slow<br />
plug-ins would use A-J and fast ones L-Z. This idea never went anywhere.<br />
<br />
Late versions had a [[BNC connector]] instead of a [[UHF connector]].<br />
<br />
Types [[K]] and [[G]] are the only letter-series plug-ins<br />
where the Gain vernier is not concentric with the step attenuator.<br />

The '''Tektronix Type W''' is a differential comparator plug-in amplifier for [[500-series scopes]]. <br />
Its bandwidth varies from 23 MHz to 8 MHz depending on gain. Only modestly <br />
faster than its predecessor, [[Z|Type Z]], Type W extends performance in <br />
terms of sensitivity, reaching 1 mV/div. <br />
<br />
It achieves 20,000 to 1 common-mode rejection at DC and low frequencies.<br />
It has a built in precision variable voltage supply, "V<sub>c</sub>", <br />
which is controlled by a ten-turn pot and can vary from either -1.1 V to +1.1 V or -11 V to +11 V. <br />
<br />
Type W has two signal inputs, "A" and "B". <br />
A mode switch selects between displaying A-Vc, A-B, or Vc-B. <br />
The "A-B" mode is particularly useful for displaying the current in a sense resistor, <br />
while the other modes provide "slideback" measurements of small variations superimposed on a large constant. <br />
<br />
An output of V<sub>c</sub> is provided on the front panel of the Type W. Unlike the [[Z|Type Z]],<br />
Type W has two gain axes, a decade attenuator and a 1-2-5-10-20-50 selector, <br />
reminiscent of [[D|Type D]] from ten years before.<br />
<br />
Type W is the only letter-series plug-in with an "infinite resistance" input mode selectable at the front panel.<br />
([[1A5|Type 1A5]] has an internal jumper that can be cut.)<br />
<br />
In the letter-series timeline of differential comparators, Type W, [[introduced in 1965]], <br />
follows [[Z|Type Z]] and precedes [[1A5|Type 1A5]].<br />

}}<br />
The '''Tektronix Type S''' is a plug-in for measuring semiconductor diode recovery characteristics.<br />
It fits in [[500-series scopes]]. It can be thought of as having two parts: a<br />
stimulus subsystem and a measurement subsystem. The stimulus comes from [[mercury switch]] that<br />
drives a [[ECC86|6GM8/ECC86]] tube that operates in a current-steering mode. The measurement subsystem<br />
is a wideband amplifier that converts the single-ended voltage on the diode under test to the <br />
differential signal that the oscilloscope mainframe takes. One terminal of the diode is grounded.<br />
<br />
Measurements with the Type S are typically made by applying a current step to the diode while <br />
observing the voltage across the diode.<br />
<br />
The Type S was [[introduced in 1960]] and produced through 1966.<br />

}}<br />
The '''Tektronix Type R''' is a plug-in for [[500-series scopes]]. It is designed to measure risetime of a NPN and PNP transistors, <br />
but it works well with FETs as well.<br />
<br />
Type R can operate in grounded-emitter or grounded-base configurations. <br />
In the grounded-emitter configuration, it provides a variable collector voltage through a collector resistor <br />
which is used to sense the collector current. It provides a base bias voltage and a base pulse signal, <br />
fed to the base of the transistor through a resistor. The base pulse is generated by a [[mercury switch]] <br />
and its rise time is specified to be less than 5 nanoseconds. <br />
Base and collector bias conditions can be set independently. <br />
<br />
The collector signal is AC-coupled to <br />
an amplifier whose output is fed to the oscilloscope. The Type R has its own on-board low-voltage, <br />
high-current regulated power supplies which feature germanium power transistors.<br />
<br />
Type R was [[introduced in 1958]], along with the [[551]], [[533]], and [[543]] mainframes,<br />
and the Type [[H]] plug-in. It is the first plug-in with transistors. It was dropped after 1966.<br />

}}<br />
The '''Tektronix Type P''' plug-in is a calibration aid [[introduced in 1959]] <br />
for [[500-series scopes]]. <br />
<br />
It applies a fast (4 nanosecond risetime) voltage step to the mainframe vertical amplifier, <br />
via plug-in connector pins 1 and 3. <br />
The Type P is designed to simulate a perfectly-adjusted Type [[K]] <br />
plug-in being driven by a Type [[107]] square-wave generator, and is<br />
used when adjusting the peaking coils and the [[delay line]]. <br />
The idea is to calibrate a mainframe using Type P, <br />
then use this mainframe and a 107 to calibrate other plug-ins.<br />
<br />
The Type P does not contain any tubes, transistors, or tunnel diodes. <br />
It does contain a [[selenium rectifiers|selenium rectifier]] and a [[mercury switch]]. <br />
The selenium rectifier in the Type P has four sections and full-wave rectifies<br />
the 6.3 V<sub>AC</sub> that is supplied by the scope mainframe on pins 13 and 14. <br />
The 120 Hz (assuming 60 Hz mains) component of the full-wave rectified waveform<br />
is applied to the coil of the mercury switch to drive the opening and closing<br />
of the contacts. An adjustable fraction of the DC component of the full-wave <br />
rectified waveform is applied to the coil of the mercury switch to create a <br />
constant component in the magnetic field to bias the switch contacts to the<br />
best operating point.<br />
<br />
The Type P was the only new plug-in for [[introduced in 1959|1959]], except for the upgrade<br />
from Type 53/54[[C]] to Type [[CA]]. It was dropped after 1963, replaced by the [[TU-7]].<br />

The '''Tektronix Type O''' is a [[letter-series and 1-series plug-ins|letter-series plug-in]] that contains two op-amps. <br />
<br />
The input and feedback networks of the op-amps can be configured from the front panel using knobs and/or user-supplied components.<br />
There are sockets on the front panel for banana plugs. <br />
<br />
Type O also has a regular signal input that does not involve the op-amps. <br />
A mode switch selects which op-amp's output will be displayed, or the regular signal input.<br />
<br />
Regular signal bandwidth is 25 MHz, maximum sensitivity is 50 mV/div,<br />
op-amp gain-bandwidth product is 15 MHz, and open-loop DC gain is 2500.<br />
<br />
Type O was [[introduced in 1962|introduced in mid-1962]] and was<br />
available through 1973, making it the next-longest-lived plug-in, behind [[CA|Type CA]].<br />
<br />
The Type O can be used with any of the following adapters: <br />
[[013-081]], [[013-068]], [[013-048]], [[013-0048-01]], [[013-0049-01]], [[013-0086-00]], [[013-0067-00]] (manual below).<br />

The '''Tektronix Type M''' is a four-channel plug-in for [[500-series scopes]]. <br />
Early versions had [[UHF connector]]s for the inputs. <br />
Later versions have [[BNC connector]]s for the inputs. <br />
<br />
Type M was [[introduced in 1962]], along with the [[O|Type O]], and dropped after 1972.<br />
<br />
{{MissingSpecs}}<br />
<br />
The risetime is 17 nanoseconds, bandwidth is DC to 20 MHz.<br />
Maximum sensitivity is 20 mV/div.<br />
Each channel can be AC or DC coupled, inverted or straight, or disabled entirely. The enabled channels can<br />
operate in CHOP or ALT mode.<br />
<br />
==Internals==<br />
Each input goes through a step attenuator, <br />
is clamped by a neon bulb, <br />
and then is fed to the grid of a cathode follower <br />
made with a [[7586]] Nuvistor tube. <br />
Next, the signal goes to a PNP differential amplifier. <br />
Diodes in series with the collector signal <br />
of this differential amplifier are used for input channel switching.<br />
An internal differential signal bus connects <br />
the switched outputs of each of the input channels <br />
and feeds the signal to the output amplifier, <br />
which drives pins 1 and 3 of the [[500-series plug-in connector]]. <br />
The output amplifier is two [[12AU6]] pentodes <br />
connected as a differential amplifier, <br />
followed by a [[12AT7]] dual triode acting <br />
as a cathode follower to drive the output <br />
with a relatively low impedance.<br />

Type 53K/54K was [[introduced in 1955|introduced in March 1955]] along with the [[541]]/[[545]].<br />
At that time, it was the only plug-in that could utilize the<br />
new mainframes' speed; the redesigned Types [[A]], [[B]], and [[C]]<br />
weren't ready until August 1956. In August 1955, just five months<br />
after introduction, it was renamed Type 53/54K, and, in 1959,<br />
when the 541A/545A mainframes came out, it got its final name, Type K.<br />
It was dropped after 1970.<br />
<br />
Type K was the fastest of the single-channel plug-ins.<br />
Tek did not equal it until Type [[L]] in 1957,<br />
and did not exceed it until Type [[1A1]] in 1964.<br />
<br />
Earlier single-channel plug-ins had two inputs and a<br />
switch to select between them, making it convenient<br />
to probe two test points at once. The Type K design<br />
could not tolerate the extra stray capacitance,<br />
and the feature was dropped, never to return.<br />
<br />
The name was deliberately chosen to be halfway into the alphabet. Slow<br />
plug-ins would use A-J and fast ones L-Z. This idea never went anywhere.<br />
<br />
Late versions had a [[BNC connector]] instead of a [[UHF connector]].<br />
<br />
Types [[K]] and [[G]] are the only letter-series plug-ins<br />
where the Gain vernier is not concentric with the step attenuator.<br />

The '''Tektronix Type H''' is a single-channel plug-in for [[500-series scopes]]. It provides two<br />
inputs and has a switch to select between them. The rise time of the plug-in is 20 ns, bandwidth is 15 MHz.<br />
The sensitivity ranges from 5 mV/cm to 20 V/cm. A design compromise, Type H is not as <br />
fast as [[B|Type B]], but it is DC-coupled on all ranges.<br />
<br />
Later Type H models use a [[Turret attenuators|turret attenuator]]. <br />
Type H with S/N less than 10,000 have ordinary attenuators.<br />
<br />
Type 53/54H was [[introduced in 1958]], along with the [[533]] and [[543]], renamed Type H in 1959, <br />
and dropped after 1970.<br />

The '''Tektronix Type G''' is a plug-in differential amplifier for [[500-series scopes]].<br />
<br />
Unlike the [[D|Type D]], the Type G is optimized for RF, achieving only a 100 to 1 common-mode<br />
rejection ratio but operating all the way to 20 MHz. <br />
Unlike "comparator" plug-ins such as the [[W|Type W]] and [[Z|Type Z]], <br />
the Type G does not contain an internal precision variable voltage source. <br />
It is for measuring the difference between two externally applied input signals. <br />
Its maximum sensitivity is 50 mV/div. It has seven tubes.<br />
<br />
Its name changed twice. Type 53G was [[introduced in 1955|introduced in March 1955]] along with the<br />
[[541]]/[[545]], but it was only specified to 10 MHz in a [[535]], and its<br />
performance in a fast mainframe was not documented. When the mainframe cabinet styles<br />
were revamped in August 1956, the Types 53[[A]], 53[[B]], 53[[C]] and 53G were<br />
all upgraded (sped up) and renamed; Type 53G became Type 53/54G. It was the only<br />
early plug-in that did not go through the awkward "53x/54x" phase.<br />
In 1959 it became Type G with no further change in design. It was dropped after 1970.<br />
<br />
Types G and [[K]] are the only letter-series plugins<br />
where the Gain vernier is not concentric with the step attenuator.<br />

The '''Tektronix Type E''' is a low-level differential amplifier plug-in for [[500-series scopes]].<br />
The sensitivity ranges from 50 μV/div to 10 mV/div. The input is an [[XLR connector]] feeding <br />
directly into the grids of a [[12AX7]] differential amplifier. <br />
<br />
Despite the DC-coupled input stage, the Type E is an AC-coupled amplifier.<br />
It has front panel knobs for selecting the low-frequency and high-frequency cutoff.<br />
It achieves a 50,000 to 1 common mode rejection ratio. Maximum bandwidth is 60 kHz.<br />
It has seven tubes on a shock-mounted subchassis.<br />
<br />
The Type 53E/54E was [[introduced in 1955]]. <br />
Along with Types [[G]] and [[K]], it was the first plug-in offered after, not during, <br />
the original [[531]]/[[535]] introduction in 1954.<br />
The nomenclature was revised after just a few months, to 53/54E. <br />
In 1959, when the A-suffix mainframes came out, all plugins dropped the "53/54". <br />
Type E was dropped after 1968.<br />
