5030

Manuals – Specifications – Links – Pictures

The Tektronix 5030 is a dual-beam oscilloscope that was introduced in 1969 (no longer listed in the 1973 catalog). There is a portable benchtop model, the 5030, and a rack-mount version, the R5030. The sister model 5031/R5031 is an almost identical (analog) storage scope.

The 5030s feature differential inputs on both channels, with additional inputs for 125-turn probes (P6021 or P6019). 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. Unlike the 576 the 12 lamps required for each deflection factor subdisplay are driven directly with cam switches. Only the first and last steps on the time/div and volts/div switches are labelled on the front panel.
