| The '''Tektronix 5031''' is a dual-beam storage oscilloscope. There is a benchtop model, the 5031,
| | #redirect[[5031]] |
| and a rack-mount model, the R5031. They do not take plugins.
| |
|
| |
|
| The readout system uses small dot matrix displays external to the CRT, similar to the [[576]] curve tracer.

| The channel-1 and channel-2 input attenuators use a rotary barrel cam that moves several small contact
| |
| arms to select the desired path through the attenuator networks.
| |
| The design is similar to that seen in several 7000-series plug-ins.
| |
| The front-end amplifier starts with a differential amplifier formed by
| |
| both halves of a [[151-1027-00]] dual JFET, Q46, followed by a dual PNP.
| |
| The rest of the signal path comprises differential amplifiers made of discrete
| |
| BJTs, including the deflection amplifier, which uses [[SE7056]] transistors for
| |
| its output stage.
| |
| | |
| The 5031 makes extensive use of relays in the signal path.
| |
| | |
| The 5031 has -4.1kV on the CRT cathode, and no post-deflection acceleration.
