The С1-122 (Cyrillic; latin transliteration S1-122) is a general-purpose 100 MHz non-storage, large screen scope made by the Soviet Research and Development Institute of Radio Measuring Instruments in Vilnius (present-day Lithuania). It takes two vertical and one horizontal plug-in. It replaced the earlier С1-91 that did not have sufficient power supply capacity for the newer plug-ins[1].
It is similar to the Tektronix 7603 though with a number of significant differences:
- it is noticeably larger
- the channel switching controls are electronic, not mechanical, and contain indicator LEDs
- the calibrator has different output voltages and frequencies
- there are no rear-panel connections for sweep gate or Z axis
- the probe power connectors are a Soviet type
- there is a mercury-column type hours counter on the rear
The readout is different from its predecessors, the С1-91 and С1-115. Instead of their vector-type character generator, it uses a dot matrix format.
The example in the photographs is labelled in German, but ones labelled in Russian also exist.
