  This paper presents an implementation of a multi-channel measuring data acquisition interface of quadrupole and sextupole magnet power supplies (MPS) for Taiwan Photon source (TPS) withLabVIEW as the developing tool. The multi-channel measuring data acquisition interface could reduce quantity of measurement instrument and loading of operator at the MPS acceptance test. The instrument devices of measurement system include a multiplexer 、 a dynamic signal analyzer (DSA) and a multi-channel digital voltage meter (DVM), GPIB is the communication protocol betweenthe multi-channel measuring data acquisition interfaceand instruments. There are threeanalyzing procedure for the output currentof MPSin 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, 3) the linear error function fitting of output current by LabVEW toolbox;after these three analyzing procedureis completed, the performance of each MPS can be automatically generatedas a Microsoft Word report file.
