Abstract

PURPOSE:To secure the remote measurement in an effective way for the envelope delay characteristics, by receiving the transmission signal obtained by adding the synchronizing relative signal to the modulation output via the TV transmission part to be measured and then reproducing the reference signal from the reproduced synchronizing relative signal and based on the integer ratio relation. CONSTITUTION:At the transmission side, the output of amplitude modulator 104 is supplied to mixture part 105, and the blanking mixture is given to horizontal synchronizing signal fH extracted from divider 111 in the form of the driving signal. Then the horizontal synchronizing signal and others are added to the modulation output for transmission. At the measurement part, the transmission signal sent from the transmission part is received at input amplifying part 201 via the TV transmission part to be measured, and one of the outputs receives synchronizing isolation 202 to obtain signal fH. Then reference signal f0 is reproduced from divider 209 and based on the integer ratio relation of signal fH or the like. And the envelope detection output received envelope curve detection 213 is displayed on CRT218. In this way, the effective remote measurement is possible for the envelope delay characteristics.
