The 7104 is a 1GHz mainframe that takes [[7000-series plug-ins]], two vertical and two horizontal.
The '''Tektronix 7104''' is a 1 GHz, non-storage 7000-series oscilloscope mainframe that takes two [[7000-series_plug-ins#Vertical plug-ins|7000-series vertical plug-ins]] and two [[7000-series_plug-ins#Horizontal plug-ins|7000-series horizontal plug-ins]].  It was introduced in 1978.  There is also a rack-mount version, the [[R7103]], albeit with only one horizontal bay.
A typical configuration would be two [[7A29]] vertical amplifiers plus a [[7B15]] and a [[7B10]] time base.


The scope employs a [[micro-channel plate]] CRT design to get good screen intensity at high sweep speeds with moderate acceleration voltage.
The scope employs a [[micro-channel plate]] (MCP) CRT design to get good screen intensity at high sweep speeds with moderate acceleration voltage. The benefit is especially noticeable at low repetition rates.


==Specifications==
The high horizontal speed necessitated using [[distributed deflection plates]] also for the horizontal deflection system, which reaches a bandwidth of 350 MHz. 
Option 2 adds a horizontal delay line to make the high horizontal bandwidth available for X-Y mode at a phase shift of <2&deg; up to 50 MHz, nullable at any frequency up to 250 MHz.


* Bandwidth: 1 GHz (with [[7A29]]) rise time < 350 ps
The [[7A29]] 1 GHz vertical amplifier and the  [[7B15]]/[[7B10]] time base pair were introduced along with the 7104 to match the system bandwidth. 
* Fastest calibrated sweep: 200 ps/div (with [[7B10]])
 
[[Val Garuts]] was the initial project leader.  [[Gene Andrews]] took over the project lead about half way through the seven year development. [[John Addis]] was the Project Engineer for the vertical system.  He designed the 7A29 plugin and its [[H500]] and [[H476]] ICs (the latter was also used in the 7104 mainframe).  [[Wink Gross]] designed the 7104 main vertical amplifier including the channel switch, the main vertical output amplifier and its [[H477]] IC.  [[Dave Morgan]] designed the mainframe horizontal amplifier, and [[Art Metz]] designed the Z axis system.  [[Dennis Hall]] was the project leader for the CRT.  [[Aris Silzars]] designed the vertical deflection plate structure and managed the acquisition of the microchannel plate. [[Conrad Odenthal]] designed the box lens for the CRT.

==MCP protection==
The Micro Channel Plate's amplification degrades irreversibly with operation, in proportion to the log of total charge passed per display area. 
For this reason, continued operation with a steady trace and especially at large beam currents must be avoided.  ''The 7104 should '''not''' be used with plug-ins that generate a slow continuous sweep, or vector graphics. This includes [[:Category:7000 series sampling plugins|sampling plug-ins]], [[:Category:7000 series spectrum analyzer plugins|spectrum analyzers]], [[:Category:7000 series logic analyzer plugins|logic analyzers]], and the [[7D20]] digitizer.''
 
The 7104 contains a "limited viewing time" circuit to assist with observing this restriction. 
At beam currents above 0.2 μA, a yellow indicator illuminates, and the beam will be shut down after 20 minutes. 
The limit time drops to two minutes at an average beam current of 2 μA, and also limits the average current to that value. 
Single-shot display current is not affected. 
 
Despite this limiter, older instruments often exhibit darkening of the screen around the horizontal center line to some degree (see [[Media:Tek7104-200ps-singleshot-sin1-1g.jpg|screen shot]]).
 
==Internals==
 
The 7104 makes extensive use of custom integrated circuits and hybrid circuits, inter alia, the [[155-0174-00]] Delay Line Compensator, [[155-0173-00]] Vertical Channel Switch, [[155-0176-00]] Vertical Output Amplifier, [[155-0194-00]]/01/02/03 CRT Termination, [[155-0175-00]] Trigger Amplifier, [[155-0178-00]] Horizontal Output Amplifier, [[155-0012-00]] Z-Axis controller/amplifier, and [[155-0067-02]] SMPS controller.  The high-speed amplifiers use [[Hypcon]] ceramic packages that use elastomer-based frames for coupling chip connections to the circuit board at constant impedance.  The signal connections are differential throughout, and the signal path was optimized for matching and low reflection, including the plugin to mainframe card-edge connectors and the use of stripline and coplanar waveguide techniques right up to the CRT.
 
The 7104's amplifiers use a then novel scheme of "feed-beside" compensation ([[Patent US 4132958A]]) where instead of matching the HF response to the LF response, the LF response is determined by off-the-shelf operational amplifiers in parallel to the high-speed amplifiers, with a number of adjustable R-C time constants to compensate for thermal and other LF effects.  The same technique is employed in the [[7A29]] amplifier plug-in.
 
===Power Supply===
The 7104 uses a switch-mode power supply.
 
Module A23 (schematic page <14>) contains the mains rectifier, base drive circuitry, and power transistors of the inverter (aka, switcher).
These transistors produce a 25 kHz waveform that is fed to the primary of T1310 ([[120-1183-00]]), whose secondaries provide the power for the rest of the scope.
 
Module A24 (also on schematic page <14>) contains the inverter control circuit and rectifiers for the secondaries of T1310. The inverter control circuit uses the [[155-0067-02]] inverter control IC, which is U1275.
 
Module A25 (schematic page <15>) contains the low-voltage regulators.
There are independently regulated and current-limited sections for the −50 V, −15 V, +5 V, +15 V and +50 V rails.
Each section has an opamp and a BJT output transistor in emitter-follower configuration.
 
The opamps need power, too.
To avoid a dependency cycle, the power supplies for the opamps are separate low-current, low-efficiency zener clamps that in no way depend on the −50 V, −15 V, +5 V, +15 V or +50 V regulators.
The power supplies for the opamps produce −22 V, −5.6 V, +5.6 V, and +22 V.
To avoid exceeding the opamps' limit of 30 V total rail voltage, each opamp either gets −22 V and +5.6 V, or −5.6 V and +22 V, depending on whether it needs more output swing in the positive or negative direction.
 
The +50 V section produces the reference voltage ("50VS") for the other sections. It uses a 9 V zener diode, VR1412, as a reference.
 
The dependency relationship of the supplies is:
* The −50 V, −15 V, +5, and +15 V sections depend on
** the +50 V supply for reference voltage,
** the opamp supplies for to power their opamps, and
** the A24 semi-regulated rectifier outputs
* The +50 V depends on
** the opamp supplies (+22 V and −5.6 V) for to power its opamp,
** the A24 semi-regulated rectifier outputs (−54 and +54 V)
* The opamps supplies depend on
** the A24 semi-regulated rectifier outputs
* The semi-regulated rectifier outputs depend only on mains power to enter tick/burst mode. However, to enter normal mode, a variety of things need to be working properly.

The Tektronix 7104 is a 1 GHz, non-storage 7000-series oscilloscope mainframe that takes two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins. It was introduced in 1978. There is also a rack-mount version, the R7103, albeit with only one horizontal bay.

The scope employs a micro-channel plate (MCP) CRT design to get good screen intensity at high sweep speeds with moderate acceleration voltage. The benefit is especially noticeable at low repetition rates.

The high horizontal speed necessitated using distributed deflection plates also for the horizontal deflection system, which reaches a bandwidth of 350 MHz. Option 2 adds a horizontal delay line to make the high horizontal bandwidth available for X-Y mode at a phase shift of <2° up to 50 MHz, nullable at any frequency up to 250 MHz.

The 7A29 1 GHz vertical amplifier and the 7B15/7B10 time base pair were introduced along with the 7104 to match the system bandwidth.

Val Garuts was the initial project leader. Gene Andrews took over the project lead about half way through the seven year development. John Addis was the Project Engineer for the vertical system. He designed the 7A29 plugin and its H500 and H476 ICs (the latter was also used in the 7104 mainframe). Wink Gross designed the 7104 main vertical amplifier including the channel switch, the main vertical output amplifier and its H477 IC. Dave Morgan designed the mainframe horizontal amplifier, and Art Metz designed the Z axis system. Dennis Hall was the project leader for the CRT. Aris Silzars designed the vertical deflection plate structure and managed the acquisition of the microchannel plate. Conrad Odenthal designed the box lens for the CRT.

MCP protection

The Micro Channel Plate's amplification degrades irreversibly with operation, in proportion to the log of total charge passed per display area. For this reason, continued operation with a steady trace and especially at large beam currents must be avoided. The 7104 should not be used with plug-ins that generate a slow continuous sweep, or vector graphics. This includes sampling plug-ins, spectrum analyzers, logic analyzers, and the 7D20 digitizer.

The 7104 contains a "limited viewing time" circuit to assist with observing this restriction. At beam currents above 0.2 μA, a yellow indicator illuminates, and the beam will be shut down after 20 minutes. The limit time drops to two minutes at an average beam current of 2 μA, and also limits the average current to that value. Single-shot display current is not affected.

Despite this limiter, older instruments often exhibit darkening of the screen around the horizontal center line to some degree (see screen shot).

Internals

The 7104 makes extensive use of custom integrated circuits and hybrid circuits, inter alia, the 155-0174-00 Delay Line Compensator, 155-0173-00 Vertical Channel Switch, 155-0176-00 Vertical Output Amplifier, 155-0194-00/01/02/03 CRT Termination, 155-0175-00 Trigger Amplifier, 155-0178-00 Horizontal Output Amplifier, 155-0012-00 Z-Axis controller/amplifier, and 155-0067-02 SMPS controller. The high-speed amplifiers use Hypcon ceramic packages that use elastomer-based frames for coupling chip connections to the circuit board at constant impedance. The signal connections are differential throughout, and the signal path was optimized for matching and low reflection, including the plugin to mainframe card-edge connectors and the use of stripline and coplanar waveguide techniques right up to the CRT.

The 7104's amplifiers use a then novel scheme of "feed-beside" compensation (Patent US 4132958A) where instead of matching the HF response to the LF response, the LF response is determined by off-the-shelf operational amplifiers in parallel to the high-speed amplifiers, with a number of adjustable R-C time constants to compensate for thermal and other LF effects. The same technique is employed in the 7A29 amplifier plug-in.

Power Supply

The 7104 uses a switch-mode power supply.

Module A23 (schematic page <14>) contains the mains rectifier, base drive circuitry, and power transistors of the inverter (aka, switcher). These transistors produce a 25 kHz waveform that is fed to the primary of T1310 (120-1183-00), whose secondaries provide the power for the rest of the scope.

Module A24 (also on schematic page <14>) contains the inverter control circuit and rectifiers for the secondaries of T1310. The inverter control circuit uses the 155-0067-02 inverter control IC, which is U1275.

Module A25 (schematic page <15>) contains the low-voltage regulators. There are independently regulated and current-limited sections for the −50 V, −15 V, +5 V, +15 V and +50 V rails. Each section has an opamp and a BJT output transistor in emitter-follower configuration.

The opamps need power, too. To avoid a dependency cycle, the power supplies for the opamps are separate low-current, low-efficiency zener clamps that in no way depend on the −50 V, −15 V, +5 V, +15 V or +50 V regulators. The power supplies for the opamps produce −22 V, −5.6 V, +5.6 V, and +22 V. To avoid exceeding the opamps' limit of 30 V total rail voltage, each opamp either gets −22 V and +5.6 V, or −5.6 V and +22 V, depending on whether it needs more output swing in the positive or negative direction.

The +50 V section produces the reference voltage ("50VS") for the other sections. It uses a 9 V zener diode, VR1412, as a reference.

The dependency relationship of the supplies is:

  • The −50 V, −15 V, +5, and +15 V sections depend on
    • the +50 V supply for reference voltage,
    • the opamp supplies for to power their opamps, and
    • the A24 semi-regulated rectifier outputs
  • The +50 V depends on
    • the opamp supplies (+22 V and −5.6 V) for to power its opamp,
    • the A24 semi-regulated rectifier outputs (−54 and +54 V)
  • The opamps supplies depend on
    • the A24 semi-regulated rectifier outputs
  • The semi-regulated rectifier outputs depend only on mains power to enter tick/burst mode. However, to enter normal mode, a variety of things need to be working properly.
