Dear, i have a labview programme for SRS 830 lock in amplifier and problem is that the output is depends on the sensitivity .. as we change the sensitivity from 500mv to 1v then output dramaticaly changes . auto gain function is not working . so i am wonder that on what sensitivity the output is correct. please help me to overcome this problem by starting the auto gain function. i am attaching that vi. when i execute vi at autogain then it shows some error and stop.

'this error' means what? Timeout or parameter error? If it's a parameter error, then you really have to check the manual to see if that is supported.
