METHOD FOR ADJUSTING PHASE RELATIONSHIP BETWEEN SIGNALS IN A MEASURING APPARATUS, AND A MEASURING APPARATUS

摘要

A measuring apparatus having a frequency-swept heterodyne-type frequency converter equipped with a frequency-swept signal source and a multiplier includes means for detecting the timing of reference burst signals that have been subjected to frequency conversion by the frequency converter, with the frequency of the output signals of the frequency-swept signal source locked; means for generating periodic pulse signals; and means for adjusting the phase relationship between the pulse signals and the reference burst signals using the detected timing; and means for sweeping the frequency of the output signals of the frequency-swept signal source using pulse signals that have been subjected to a phase relationship adjustment.
