The '''Tektronix 567''' is a [[sampling oscilloscope]] mainframe [[introduced in 1962]].


According to Stan Griffiths,
It has a digital plug-in unit, the [[6R1]] or [[6R1A]], that can be used to measure waveform characteristics such as rise time. 
This digital unit provides a go/no-go output based on waveform characteristics. 
This feature makes the 567 particularly useful in production testing for tasks such as binning logic gates based on their speed. 


"It looks like there were two different serial number runs of 567's.
The development of the 567 (and 6R1) was led by [[Sam McCutcheon]].
 
The 567 came after the [[661]] and before the [[568]] and its associated [[230]] Digital Unit.
 
The 567 is a self-contained oscilloscope, but is also used as a component of S2000- and
S3000-series measurement systems. In that capacity, it typically uses one of the programmable
plug-ins, [[S-311]], [[S-300]], or [[S-301]].

==Operation==
The 567 has three plug-in compartments. 
The left compartment holds a 3S-series sampling vertical unit such as a [[3S2]]. 
The center compartment holds a 3T-series sampling sweep unit such as a [[3T77]].
The right compartment holds the digital unit, either a [[6R1]] or a [[6R1A]].
It is possible to operate a 567 without the digital unit but in that configuration it provides only the functionality that a [[561]] provides.
 
The [[6R1]] and [[6R1A]] digital units have several different operating modes. 
These modes can be classified as time measurement or voltage measurement. 
One time measurement mode, for example, shows the time delay between the rising pulse edge on input A and the falling pulse edge on input B. 
This is useful for measuring the speed of a logic gate such as an inverter. 
One of the voltage measurement modes displays the difference between the input A voltage at on time and the input A voltage at some other time. 
This is useful for measuring the peak-to-peak amplitude of a signal.
 
==Internals==
The mechanisms used by the digital unit are a sample and hold circuit, a comparator, a counter, and a switched tap voltage divider. 
The digital unit takes its input from the vertical signal produced by the sampling unit.
Therefore, it operates on a low-speed signal, somewhat similar to the intermediate frequency (IF) in a superheterodyne radio. 
 
The user of the 567 positions two cursors along the X-axis.
These cursors define two times and two voltages. 
The tapped voltage divider produces several voltages along the interval spanned by the two cursor voltages – 10%, 20%, 27%, 50%, 73%, 80%, and 90%.
These voltages are used for making measurements such as the 10%-to-90% rise time. 
In this case, a counter is reset and started when the signal passes through the 10% voltage. 
The counter counts the number of cycles of a built-in crystal clock.
When the signal reaches the 90% voltage, the counter is stopped and the count is displayed on the [[nixie tube]] digital numeric readout.
The units and decimal place of the digital unit are controlled by switch contacts on the timing unit plug-in,
which connect to the digital unit through a multi-pin connector in the 567. 
 
The 567 does not have any post-deflection acceleration of the beam.
The CRT circuit uses two [[5642]] high-voltage rectifier tubes, one (V822)
to generate the CRT cathode voltage (−3.3 kV) and one (V832) to generate the CRT
grid bias voltage.  CRTs used were [[T5032]] (earlier) and [[T5611]] (later models).
 
A 567 can perform remotely controlled measurements by connecting a [[262]]
programmer to the [[6R1]] or [[6R1A]] that is in the 567.
 
There is an extender plug-in, the [[067-0505-00]], that allows a [[6R1]] or [[6R1A]]
to be operated outside the plug-in bay of the 567 for maintenance purposes.

The Tektronix 567 is a sampling oscilloscope mainframe introduced in 1962.

It has a digital plug-in unit, the 6R1 or 6R1A, that can be used to measure waveform characteristics such as rise time. This digital unit provides a go/no-go output based on waveform characteristics. This feature makes the 567 particularly useful in production testing for tasks such as binning logic gates based on their speed.

The development of the 567 (and 6R1) was led by Sam McCutcheon.

The 567 came after the 661 and before the 568 and its associated 230 Digital Unit.

The 567 is a self-contained oscilloscope, but is also used as a component of S2000- and S3000-series measurement systems. In that capacity, it typically uses one of the programmable plug-ins, S-311, S-300, or S-301.

Operation

The 567 has three plug-in compartments. The left compartment holds a 3S-series sampling vertical unit such as a 3S2. The center compartment holds a 3T-series sampling sweep unit such as a 3T77. The right compartment holds the digital unit, either a 6R1 or a 6R1A. It is possible to operate a 567 without the digital unit but in that configuration it provides only the functionality that a 561 provides.

The 6R1 and 6R1A digital units have several different operating modes. These modes can be classified as time measurement or voltage measurement. One time measurement mode, for example, shows the time delay between the rising pulse edge on input A and the falling pulse edge on input B. This is useful for measuring the speed of a logic gate such as an inverter. One of the voltage measurement modes displays the difference between the input A voltage at on time and the input A voltage at some other time. This is useful for measuring the peak-to-peak amplitude of a signal.

Internals

The mechanisms used by the digital unit are a sample and hold circuit, a comparator, a counter, and a switched tap voltage divider. The digital unit takes its input from the vertical signal produced by the sampling unit. Therefore, it operates on a low-speed signal, somewhat similar to the intermediate frequency (IF) in a superheterodyne radio.

The user of the 567 positions two cursors along the X-axis. These cursors define two times and two voltages. The tapped voltage divider produces several voltages along the interval spanned by the two cursor voltages – 10%, 20%, 27%, 50%, 73%, 80%, and 90%. These voltages are used for making measurements such as the 10%-to-90% rise time. In this case, a counter is reset and started when the signal passes through the 10% voltage. The counter counts the number of cycles of a built-in crystal clock. When the signal reaches the 90% voltage, the counter is stopped and the count is displayed on the nixie tube digital numeric readout. The units and decimal place of the digital unit are controlled by switch contacts on the timing unit plug-in, which connect to the digital unit through a multi-pin connector in the 567.

The 567 does not have any post-deflection acceleration of the beam. The CRT circuit uses two 5642 high-voltage rectifier tubes, one (V822) to generate the CRT cathode voltage (−3.3 kV) and one (V832) to generate the CRT grid bias voltage. CRTs used were T5032 (earlier) and T5611 (later models).

A 567 can perform remotely controlled measurements by connecting a 262 programmer to the 6R1 or 6R1A that is in the 567.

There is an extender plug-in, the 067-0505-00, that allows a 6R1 or 6R1A to be operated outside the plug-in bay of the 567 for maintenance purposes.

Models

According to Stan Griffiths,

It looks like there were two different serial number runs of 567's.

Bench models:

  • 000101-000750 = 650 instruments
  • 002000-003280 = 1280 instruments
  • Total = 1930

Rackmount models:

  • 000101-000228 = 128 instruments
  • 002000-002240 = 240 instruments
  • Total = 368

Grand Total = approx. 2300
