FIELD: the invention refers to measuring technique and may be used for measuring of a carrier frequency and a vector analysis of signals in the system of radio control. ^ SUBSTANCE: for achieving such result a line of delay, a phase shifter till 900, two multipliers, two filters of low frequencies and the second electron-ray tube are additionally added. At that the line of delay, the first multiplier, whose second input is connected with the output of the amplifier of an intermediate frequency, the first filter of low frequencies and vertical-deflection plates of the second electron-ray tube are in series connected to the output of the amplifier of an intermediate frequency. The phase shifter till 900 and the second multiplier are in series connected to the output of the amplifier of an intermediate frequency. ^ EFFECT: expansion of functional possibilities. ^ 4 dwg |
