ることを特徴とするケーブル長測定器。 A signal generation circuit that generates a measurement signal, a delay insertion circuit that inputs the output of this signal generation circuit and outputs the elapsed specified delay time, and a signal cable to be measured that inputs the output signal of the signal generation circuit at one end. A delay phase detection circuit inputs the output of the other end and the output of the delay insertion circuit to measure and output the time difference, and a delay phase detection circuit that specifies an instructed delay time to the delay insertion circuit and receives time difference information from the delay phase detection circuit. and a computer that instructs the control circuit to calculate and output the total delay time, and also converts and displays the cable length from the total delay time output by the control circuit. Cable length measuring device.
