PURPOSE:To improve the work efficiency considerably and economize measuring personnel and a measuring time, by transmitting a test signal from the other radio equipment by the control signal from one of opposite radio equipments and by measuring line conditions between two points. CONSTITUTION:The measurer operates remote control unit 3 of the first radio equipment 1 to transmit a control signal to the second opposite radio equipment 2. The control signal received by the second radio equipment is restored and is applied to remote controlled unit 5, and transmission start is instructed only for a fixed time by the timer function to count the tiem, and simultaneously, the output of test signal generator 6 is controlled to transmit the modulation wave and the nonmodulation wave dependent upon the test signal to the first radio equipment 1 in series. The measurer receives this test signal and can perform required measurement such as line conditions by measuring equipment 8. |
