Abstract

PURPOSE:To readily conduct fine adjustment and inspection of a radar indicator display unit over the entire area by reproducing a signal recorded on a video tape recorder on an input video signal of the indicator, thereby forming a signal similar to an actual echo signal. CONSTITUTION:After a video signal recorded on a video tape recorder 5 is branched to first channel of video and synchronous trigger signals and second channel of X and Y signals, the video signal and trigger signal of the first channel are separated by a video distributor 6, and introduced to a radar indicator 1. The bearing signal of the second channel is divided into X and Y signals by a distributor 9 to thereby form an X-Y signal by an X-Y signal forming circuit 10 and to be then applied to the indicator 1. Thus, the video signal recorded on the recorder 5 is indicated on an indicator display tube 1c of the indicator 1.
