Abstract

The invention belongs to the technical field of microwave signal testing, and particularly relates to a microwave signal frequency-hopping time measurement circuit. The frequency-hopping time measurement circuit comprises an attenuation unit, a frequency mixing unit and a lowpass filtering unit; the input ends of a voltage-controlled oscillation unit and the frequency mixing unit are both input ports of the measurement circuit, the output end of the voltage-controlled oscillation unit is connected with the input end of the frequency mixing unit, the output end of the frequency mixing unit is connected with the input end of the lowpass filtering unit, and the output end of the lowpass filtering unit is an output port of the measurement circuit. The microwave signal frequency-hopping time measurement circuit can effectively measure the frequency hopping time in a wide frequency range, and measurement can be conducted without additionally adding synchronizing signals or knowing the modulation frequency in advance.

Description
