FIELD: UHF measurements, possible use for testing UHF quadripoles, and also in special case for their control and adjustment.
SUBSTANCE: method includes comparing supporting and measured signals and minimizing their ratio during adjustment of quadripole. As supporting signal, signal having passed through quadripole is used, which is compared to measured signal, reflected from the input of quadripole. For realization of the method, panoramic measuring device is used, containing swaying frequency generator, ratio meter, indicators of power of supporting and measured signals, coordinated load. Supporting signal indicator is installed between output of quadripole and coordinated load for control of power passing through it, and measured signal indicator is installed between swaying frequency generator and quadripole input for controlling the signal reflected from its input.
EFFECT: lower laboriousness of quadripole testing, improved quality of quadripole parameters and increased precision of their parameter measurement.
