Implementation of a new RF monitoring system for the SRS using LabVIEW

The SRS computer control system is undergoing a programme of upgrade from a system of Concurrent Computer Corporation minicomputers to a network of PCs. The old RF monitoring system, based on CAMAC hardware, has been replaced with two industrial PC front end computers running Windows 95 and controlling Hewlett Packard instrumentation and Eurotherm Temperature Controllers. Measurements on the new system are now performed using the data acquisition software LabVIEW/sup (R)/ combined with standard PC cards for GPIB and serial communication. This paper describes the hardware and software used in this project, and also how it has been interfaced onto the existing SRS ISOLDE PC control system.
