This report describes a PC based control and data acquisition system, runni
ng under Windows. developed for testing superconducting resonators at Nucle
ar Science Centre (NSC). The rf parameters can be controlled and measured,
to calculate the quality factor Q on-line. The system also measures and mon
itors, various temperatures, pressure, vacuum and cryogenic fluid level ins
ide the cryostat during testing. Details of the system are presented.
