Abstract
Based on virtual instrumentation
a reliable and effective test platform
performing instrument control
data acquisition and data recording
has been established to evaluate linearity of high performance DCCT (DC current transducer) for digital power supply at Shanghai Synchrotron Radiation Facility (SSRF).The software in LabVIEW language was developed to perform computer communication via serial communication (RS232) and GPIB
providing a friendly user interface to the linearity test platform.This makes it easy to test the linearity and control power on or off and current output of high-precision and high-current DC constant current output power supply.The experimental data
stored in an EXCEL file
can be processed to obtain DCCT linearity
and provide basis to further analyze DCCT performance in the future.
