自校准技术在多通道测试设备中的应用

Application of Self-calibration Technology on Multi-channel Test Devices

着眼于解决多通道设备的校准问题。多通道设备的校准通过在设备设计之初内装自校准模块来实现,并使用外接设备来校准自校准模块中的基准源。输出参量采用内部自校准模块自动校准,可以大大减少设备的校准工作量。

This paper focused on solving problems in calibration of multi-channel devices. Calibration of muhi-channel devices was actualized by installing self-calibration module in the devices during the early design period, and the benchmark source in the self-calibration module was calibrated by means of external devices. Output parameters can be calibrated automatically with internal self-calibration module, which will save much time and labor in device calibration.
