Selective microvoltmeter SMV 7

Also, this device can be called: SMV7, SMV-7.

SMV 7 selective microvoltmeter - meters interference voltage - sensitive heterodyne receivers.

Used SMV 7 to measure high voltage sinusoidal and quasi-pulsed measurement interference voltages.

With measuring type antennas DP 3/ATR 2, DP 1/ATR 2 or LPA1/ATR2 - can be used as an instrument for measuring the field strength of radio interference.
