Abstract
This paper presents an implementation of a multi-channel measuring data acquisition interface of corrector magnet power supplies (CMPS) for Taiwan Photon source (TPS) with LabVIEW as the developing tool. The multi-channel measuring data acquisition interface could reduce quantity of measurement instrument and loading of operator at the CMPS acceptance test. The instrument devices of measurement system include a multiplexer, a dynamic signal analyzer (DSA) and a high-resolution digital voltage meter (DVM), GPIB is the communication interface between the multi-channel measuring data acquisition interface and instruments. There are two analyzing procedures for the output current of CMPS in the default setting of the LabVIEW program, 1) Fast Fourier Transform of output current measured by DSA, 2) long-term stability of output current measured by DVM; after these two analyzing procedures are completed, the performance of each CMPS can be automatically generated as a Microsoft Word report file.
