| Abstract: | Using 750 wave-guide in a certain reconnaissance equipment causes the frequency measurement error over the index in the instantaneous frequency measurement receiver.This paper analyzes the reason causing the error,and presents two solution methods:delays the sampling time of the frequency measurement receiver;adopts 650 wave-guide with lower cut-off frequency. |
