SR830 Lock-in Amplifier GPIB Control

Hi everyone,

 

I have developed a vi for SR380 and I can control the device successfully. However, when I send a command (e.g. OFLT) to it, the device responses about 2 sec. later. Mainly, I have designed the vi using sequences in terms of each unit in the SR830. (For example "time constant" and "signal input" sections are in two successive stacked sequences). I have also tried commanding in Measurement and Automation Explorer, it works error free and fast. If I run the program, each sequence is processed again and again. I just want to send a single command about what I want to change, but it keeps overwriting. *RST command resets the device to its default values, when I reset it, then it updates (e.g. time constant) to a new value due to time constant control in another sequence. I am new to instrument control and LabVIEW, sorry for any misconceptions, and I'll appreciate any suggestions for the solution.

Hi

 

You don't need stacked sequences for programming gpib. You can use simpler methods.

post your program including subvi's and I can give a try to streamline the speed.
