PURPOSE:To conduct the test to plural digital satellite communication systems operated by an independent clock by providing a clock matching circuit to each input and output side of a delay means of plural channels and connecting each digital satellite communication equipment to the delay means via the clock matching circuit. CONSTITUTION:Clock matching circuits 11-1-11-n, 11-1'-11-n' are provided to the input/output side of a delay means 12 to provide a delay by satellite relay in simulating way even if the clock of a digital communication equipment and a clock of a pseudo delay device are independent. Since the delay means 12 and the clock matching circuits 11-1-11-n, 11-1'-11-n' are simple and small scale in comparison with the circuit scale for other test provided to one set of multiple access connection pseudo satellite delay equipment one set of the multiple access pseudo satellite equipment is provided with plural (n) delay means 12 and the clock matching circuits 11-1-11-n, 11-1'-11-n' of the same number. Thus, one set of pseudo satellite delay equipment can conduct delay test of the n-system of digital satellite communication systems. |
