Title: Test system
Inventor: ARASAWA EIKI
IPC: G06F11/273
Filed: 1984-11-13
Abstract: PURPOSE:To reduce the influence of a noise from a digital test module to an analog system in a test system which tests the digital and analog systems simultaneously by passing a digital system test signal through an optical transmitting means. CONSTITUTION:A digital system test signal and an analog system test signal are applied simultaneously to the digital system test module TML1 and analog system test module TML2 for objects to be tested and the both are tested simultaneously. In this case, the digital system test signal is a relatively fast pulse signal and the analog system test signal is a wide-range low-level signal. Therefore, when a test module TMLi is connected to a test head THD through an electric signal line Lbi, the digital system TML1 becomes a high-level noise source and affects the analog system TML2, which is not tested stably. For the purpose, the digital system test signal is transmitted through optical interfaces OIFa and OIFb and an optical fiber OF to reduce the influence of a noise, thereby testing the analog system and digital system simultaneously.
