Electronic oscilloscope `` C1-1 '' (EO-7).
Instruments for adjusting and controlling the PTA.Since 1957, the electronic oscilloscope "C1-1" has been produced by the Rybinsk Instrument-Making Plant in accordance with the new GOST. The electronic oscilloscope "C1-1" is an analogue of the "EO-7", which has been produced since 1948. Oscilloscope type "C1-1" (EO-7) is designed to study periodic processes. It is used in factory and laboratory conditions. The sensitivity of the vertical deflection amplifier is 0.25 cm / mV. Gain 1800. Frequency distortion ± 3 dB in the range from 2 Hz to 300 kHz. Input impedance 2 MΩ ± 20% in parallel with capacitance up to 30 pF. Attenuation ratio of the attenuator 1: 1; 1:10; 1: 100 in the range from 2 Hz to 250 kHz. The sensitivity of the horizontal deflection amplifier is 4.5 cm / in. Gain 35. Frequency response unevenness ± 3 dB in the range from 2 Hz to 250 kHz. Input impedance 6 MΩ ± 20% in parallel with capacitance up to 30 pF. The input impedance of the external synchronization circuit is 0.1 MΩ ± 20% in parallel with a capacitance of up to 40 pF. There are 8 continuous sweep ranges: this is -7; 7-30; 30-130; 130-500 Hz; 500 hz-2 khz; -7; 7-25; 25-50 kHz. The nonlinearity of the sweep does not exceed 5%. There are 3 types of synchronization: internal (by the signal under investigation), external (by an external signal), from the mains (supply voltage). It is possible to supply the voltage under study directly to the vertical and horizontal plates of the CRT. The device is powered by an alternating current electrical network with a voltage of 220 V, a frequency of 50 Hz. Power consumption 120 VA. Dimensions 565x233x440 mm. Weight 24 kg.
