The '''С1-122''' (Cyrillic; latin transliteration '''S1-122''') is a general-purpose 100 MHz non-storage, large screen scope made by the [[Soviet 7000-series clones|Soviet Research and Development Institute of Radio Measuring Instruments]] in Vilnius (present-day Lithuania). It takes one horizontal and two vertical plug-ins.

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.
