Oscilloscope `` Н3013 '' (Educational).

Instruments for adjusting and controlling the PTA.The oscilloscope "H3013" (educational) was produced presumably since 1982 by the Krasnodar Plant of Measuring Instruments. The oscilloscope is intended for use in laboratory work of general education secondary schools for observing the simplest electrical processes. The range of observed periodic signals is from 0 to 10 kHz. The amplitude of periodic signals is from 20 mV to 50 V. The size of the working part of the screen is 50 x 40 mm. Beam thickness Н3013 is not more than 1 mm. The unevenness of the amplitude-frequency characteristic is not more than 50%. The total value of the voltage of direct and alternating currents supplied to the input is 50 V. The maximum value of the investigated signals is not more than 50 V. The drift of the amplifier of the channel "Y" is not more than 200 mV. The input impedance of the amplifier is 500 ± 100 kΩ. Parallel capacitance 20 pF. The minimum value of the investigated signal is 20 mV. The sweep frequency of the horizontal deflection channel of the electron beam is from 1 Hz to 10 kHz. The supply voltage from the mains is 220 V. The power consumed by the oscilloscope is 12 W.
