The invention discloses an
amplifier voltage stability batch automatic test
system which comprises a high and low temperature test box and an
amplifier automatic test box. A PXle case, a PXI controller, a multi-path
relay switch card, a direct-current power supply and a
voltage acquisition card are embedded in an automatic
amplifier test box; a
test board and a test tool are arranged in the high and low temperature test box; wherein the multi-path
relay switch card realizes independent control of each test module and freely switches signals of each test module clamp; the PXI controller is connected by adopting an RS485 standard communication protocol, and a
relay switch is triggered through high and low levels of an upper computer; the
voltage acquisition card realizes synchronous high-precision acquisition of at least 30 differential synchronous channels for two voltage signals of the test module; and the PXI controller in the PXle case outputs two paths of voltage signals acquired by the voltage acquisition card to the computer to display the acquired information in real time, generate a curve graph, automatically store data and analyze the data, so that the monitoring of the
voltage stability is realized. The problems that time and labor are wasted when instruments are built during
manual testing, personal errors are prone to occurring in the testing process, efficiency is low and the like are well solved, use is convenient, and operation is easy.
