ARRANGEMENT FOR MEASURING FREQUENCY OF INPUT SIGNAL OF PANORAMIC RADIOSET Russian patent published in 2006 - IPC G01R23/10 

FIELD: the invention refers to radio technique.

SUBSTANCE: the arrangement has in-series switched-on a receiving antenna, an input circuit, an amplifier of a high frequency, the first asynchronous detector, the first video amplifier, a differentiating circuit and vertical-deflection plates of the first oscillographic indicator. The second input of the first asynchronous detector is connected with the output of a heterodyne. The vertical-deflection plates of the oscillographic indicator are connected with the output of a frequency sweep forming block. At that the controlling inputs of the input circuit , of the amplifier of a high frequency, the heterodyne, the frequency sweep forming block are connected with corresponding outputs of a controlling block. A phase shifter till 90^0, the second asynchronous detector, the second video amplifier and the vertical-deflection plates of the second oscillographic indicator are in series connected to the output of the heterodyne. The second input of the second asynchronous detector is connected with the output of the amplifier of a high frequency. An impulse former, a key and the vertical-deflection plates of the second oscillographic indicator are in series connected to the output of the differerentiating circuit. The second input of the key is connected with the output of the video amplifier.

EFFECT: expansion of functional possibilities by way of visual analysis of complex envelope impulse signals.
