Signal output board card and automatic test system

Abstract

The invention relates to a signal output board card and an automatic test system. The signal output board card provided by the embodiment of the invention comprises a main controller, a bus module and a signal output module, wherein the bus module and the signal output module are respectively connected with the main controller. Wherein the bus module is used for connecting an upper computer and the main controller, the main controller is used for receiving an initial signal sent by the upper computer through the bus module and sending the initial signal to the signal output module, and the signal output module is used for outputting multiple paths of target analog signals in different forms according to the initial signal. The automatic test system comprises an upper computer and a signal output board card, a bus module in the signal output board card is connected with the upper computer, and the upper computer is used for generating an initial signal and sending the initial signal to a main controller through the bus module. According to the signal output board card and the automatic test system provided by the embodiment of the invention, the automatic test cost of the target equipment can be effectively reduced.

Description

technical field [0001] This application relates to the field of automated testing of electronic equipment or components, in particular, to a signal output board and an automated testing system. Background technique [0002] In the field of automated testing of electronic equipment or components used in the aerospace industry, it is often necessary to provide various types of analog signals as input stimuli for target devices. These analog signals are used to provide enabling stimuli for target devices, or provide The equipment is used for signal analysis, etc. Therefore, under normal circumstances, the combination of this multi-channel analog signal can make the target equipment enter the test state normally. However, in the prior art, different types of analog signals need to be implemented through different signal output boards, thus greatly increasing the cost of automated testing of the target device. Contents of the invention [0003] The purpose of this application ...
