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 in the 576, the twelve lamps required for each deflection factor sub-display 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.
