Universal oscilloscopes '' S1-65 '' and '' S1-65A ''.
Instruments for adjusting and controlling the PTA.Universal oscilloscopes "S1-65" and "S1-65A" have been produced since 1979 and 1981. Oscilloscopes are designed to study the shape of electrical signals by visual observation and measurement of their amplitude and time parameters in the workshop, laboratory or field conditions. Oscilloscopes "S1-65" and "S1-65A" are similar in schematic technique and appearance, But the oscilloscope "S1-65A" has an operating frequency of 50 MHz, versus 35 MHz for the oscilloscope "S1-65", as well as a larger height CRT screen, while maintaining the dimensions of the case.
