Abstract

A spectrum analyzer, which is characterized in comprising the following components: (A) a voltage-controlled oscillator for feeding a frequency of swept signal to a swept signal generator of a frequency mixer where the signal under measurement is to be input; (B) a phase lock loop for controlling the oscillation frequency of the swept signal generator; (C) a reference signal generator for sending reference signals with frequency changing at a specified interval to the phase lock loop; and (D) a sample-hold circuit for conducting sample-hold on the phase comparison output of a phase comparator constituting the phase lock loop when the reference signal generator causes the frequency to undergo a step-change, and then sending the hold-voltage to the swept signal generator.
