I definitely can associate with your problem, Brennan.
This semester I had been working with an SR810 and I ran into several
problems which I was finally able to solve in the last few weeks.
I don't know exactly what you're doing, but the problem I had was that the
SR810 stopped responding after taking data for 15 seconds or more, and then
sometimes it just flatly didn't work out at all.
What I discovered was a mistake in the SR810.VI (the configuration VI)... I
figured out (this was my first time using Labview) that the VI sends a
command to the SR810 in the wrong spot of the GPIB Send Message.VI... where
it should be sending a number for the read mode (0, 1, or 2), it is instead
sending the number 3200. Obviously, the SR810 gets confused like all hell at
th
is point, and then just doesn't know what to do, so it gives up. BTW, the
number 3200 should be being sent to the number of bytes parameter of the
GPIB Send Message.VI.
Like I said, it took me the better part of several weeks to figure this
problem out. I had tried talking to people at NI and at Stanford Research,
but they assured they have had no problems with their VIs or the instrument
itself.
I can send you a new copy of the VI tomorrow when I go back to the research
lab if you're interested, or tell you EXACTLY what to change... because you
have an SR830 and not an SR810 and who knows, they may have different VIs
altogether...
- Tell me what you want to do.
