FIELD: physics.
SUBSTANCE: device has a signal generator, connected to the input of an auxiliary antenna, series-connected mixer, input of which is connected to the output of the analysed antenna, mounted on a turn table, intermediate frequency amplifier, peak detector, the input of which is connected to the intermediate frequency amplifier, selection-storage unit, sweep-frequency generator, first output of which is connected to the second input of the mixer, and the second output to the "Reset" input of the peak detector and the "Select" input of the selection-storage unit, as well as series-connected analogue-to-digital converter (ADC), control unit, computer, where the input of the ADC is connected to the output of the selection-storage unit, and the output is connected to the computer, the first control port of the computer is connected to the control unit, connected in series to the turn table, and the second control port of the computer is connected to the signal generator.
EFFECT: automatic control of the antenna pattern measurement process and increased accuracy.
