Automatic test system used in TDS220 digital oscilloscope

This paper introduced the automatic test system which was composed of 9500B oscilloscope calibrator, GPIB, computer, cable, and so on. It mainly finished automatic test of DCV, bandwidth, trigger sensitivity, time accuracy,and it described the hardware configuration and software design based on LabVIEW. How to realize the remote control over devices, produce control signal and process measurement dada was presented by application examples.
