The Tektronix 5031 is a dual-beam split-screen, bi-stable storage oscilloscope introduced in 1969 (no longer listed in the 1973 catalog). There is a portable benchtop model, the 5031, and a rack-mount model, the R5031, as well as a sister model 5030/R5030 without storage. The 503x series are monolithic scopes (no plugins).

The 5030 and 5031 feature differential and current probe (for P6021) inputs on both channels. Input ranges are similar to the contemporary 3A9 diff/current amplifier plugin but without the variable bandwidth and DC offset controls. The horizontal deflection system is shared.

The 5031/5030 include a readout system which uses small lightbulb/fiber dot matrix displays external to the CRT, similar to that in the 576 curve tracer. Only the first and last steps on the time/div and volts/div switches are labelled.

Time base 1 μs/Div to 5 s/Div (1–2–5), magnifier × 1, 2, 5, 10, 20, 50 (1 μs/Div max.)
CMRR 100,000:1 to 100 kHz
X input 20 mV/Div to 500 mV/Div on Ext Horizontal, or Channel 2 in X-Y mode
CRT 8 × 10 Div @ 1.27 cm (0.5"), P31 phosphor

Internals

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 −4.1 kV on the CRT cathode, and no post-deflection acceleration. The 5031 uses a T7020 CRT.
