Oscilloscope S1-77 is designed to study the universal form of electrical signals in the frequency range of 10MHz-0MGts, measuring scale in the range from 0.01 V to 200 V and the time intervals of 0,1 ∙ 10 -6 to 0.4 sec.
The presence of two channels of the vertical deflection allows the simultaneous study of two signals in one scan.
Oscilloscope S1-77 used in universal design, setup and adjustment of electronic equipment in the lab, shop and field conditions.
