Abstract

PURPOSE:To increase the efficiency of space and operability of test, by providing a plurality of simulated transmission lines corresponding to various cable lengths. CONSTITUTION:When a selection control instruction of a simulated transmission line 105 is outputted from a CPU107 to an IO bus 200, this is received at an interface section 106 and a selection instruction to a relay switch 104 is outputted, for the operation of the relay switch 104. Thus, a simulated transmission system from a selected simulation transmitting circuit 105, an input connector 101, a buffer amplifier 103 to an output connector 102, is constituted for the coupling between a relay device (not shown) and the simulated transmission system. According to the instruction from a CPU107 at this state, various tests are made and the relay switch 104 is switched as required, allowing to switch the simulated transmission line 105.
