Hallo,
I have a very simple and probably outdated question, but I really had a hard time finding anything on the internet, including the NI forums.
I want to acquire data from the sr830 lockin amplifier. In the middle of one run I want to switch from the normal input (the A input on the front panel) to the differential voltage input (the A-B input on the front panel). The Sr830 manual says it should be possible:
ISRC (?) {i} The ISRC command sets or queries the input configuration. The parameter i selects A (i=0), A-B (i=1), I (1 MΩ) (i=2) or I (100 MΩ) (i=3).
But I'm not using this kind of code. I'm just using the Labview driver and its commands. I looked like 3 times through all of the commands (if you go like Instrument I/O -> Instr Drivers -> Standford Research 830) and couldn't find one that would configure this parameter. Which is odd, since I thought you should be able to control anything with Labview driver that you can control on the front panel.
I'm using Labview 2011 on Windows 7.
Does anyone know a solution to this? Am I overlooking something?
Thank you for your help.
