Trials, Tribulations, and Pitfalls Using Commercial Instruments for Data Acquisition
K.L.Unger, R.C.Lee*, R.H.Olsen (BNL)
Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) uses many commercially available instruments - for example spectrum analyzers, oscilloscopes, digital volt meters, signal generators - as integral parts of instrumentation and control systems. Typically these systems are remotely controlled. Using commercial instruments has many benefits. Manufactures have the skill, knowledge, and experience to produce high quality products. The price performance ratio is hard to duplicate. There are also disadvantages. Proprietary interfaces, single platform drivers, and reliable operation provide challenges for implementation and unattended operation. Several of the systems used at RHIC will be described. Their issues and solutions will be presented.
