Background: I am using a Stanford Research SR830 to measure the magnitude and phase of some pressure transducers; the pressure transducers are piezoresistive with a Wheatstone Bridge configuration. The SR830 is recognized on MAX, and reads things like magnitude and phase upon request, and, although not needed, the 830 responds correctly to the configuration VI in which the frequency is set. Hence, the communication link (GPIB) seems to be working.
Question: while the 830 is set to "autogain," there is a circumstance in which knowing the sensitivity is required. When I try using the 830 Read vi, set for one parameter, only predetermined parameters like magnitude or phase are permitted. The instruction to read the sensitivity is "SENS?." but the Read vi seems to only allow predetermined integer values. I investigated using a VISA Read vi, and that input is the byte count..
I checked Knowledebase and other Discussion Forum threads, but those I read were oriented toward setting or reading the usual suspects, which I can do.
Any suggestions, and what obvious solution have I overlooked? Having programmed HPIB machines decades ago, this really should not be difficult.
