Abstract

It is known to measure the frequency of microwave signals by heterodyne conversion or by transfer oscillator techniques. Heterodyne conversion frequency counters are limited in their ability to measure the frequency of pulsed microwave signals. On the other hand, while transfer oscillator frequency counters can measure the frequency of pulsed microwave signals they have limitations in measuring signals with large frequency modulation components. The present invention utilizes analog microwave frequency dividing devices to virtually instantaneously convert the signal to be measured in octave steps into the frequency regimes associated with digital frequency counters. The apparatus disclosed comprises an antenna or other device for receiving a microwave frequency signal and feeding it to an analog frequency divider system having n stages, where n is an integer, each stage dividing frequencies applied to it by a factor of 2. The output of the divider system feeds a digital counter which, in turn, feeds a digital display device which displays a number equal to 2.sup.n times the output of the digital counter and hence equal to the frequency of the received microwave signal.
