  • 1. - .. . . . . . Amplitude and phase fluctuation detector. Andrei Parmenov.ABSTRACT: The paper describes the operation principle of a device for amplitude,frequency, and phase analysis of a pulsed RF signal. Based on bandpass sampling techniquewith the use of high-performance ADCs, the device is designed as a compact computing unit.A tool developed for construction of dynamic spectra in time (spectrograms) enablesdetection of transient noise that introduces instability into a radar transmitter system. Unlikeits analogues, the device not only calculates pulse-to-pulse amplitude and phase stability of apulsed signal, but also detects parasitic noise sources that affect it. . , , , . , . . . , , 400- , . , , . , , .
