FIELD: radio measurements.
SUBSTANCE: device has measuring converter and reference signal source both connected to inputs of switch, signal transmission circuit, second switch, and controlled resistor, measuring device, control unit, comparison unit and standard voltage source. Output of first switch is connected with signal transmission circuit, controlled resistor and second switch; all the members are connected in series. Control outputs of switches are connected with first output of control unit. One output of second switch is connected with input of measuring device, and the second output is connected with the first input of comparison unit. Second input of comparison unit is connected to standard voltage source. Output of comparison unit is connected with input of control unit which has second output connected with control output of controlled resistor.
EFFECT: improved precision of measurement of parameters of signal when transmitting signals along long transmission circuits.
