Keithley 2636A Error Code: 5042

[JRy]

Hi, 

When using the attached to do a pulse sweep with the 2636A in labview, I get the following error:

Error code: 5042 - cannot perform requested action while overlapped operation is in progress.

Also, some of the included sample files give the same error.

Can anyone shed any light on this?

Hello,

Without the device itself it is going to be quite hard to see this error and work out what might be causing it. I found the following post on a Keithley forum that seems to cover the same error:

The link to the reference manual did not work for me but I have found a copy of the 2600A reference manual here:

Other than that I would check all of the actions that you are performing with the device to see if there are any conflicts where the same resource is needed for several tasks which could bring about an error such as this.

Kind Regards

Hi JRy,

I didn't check your program, but the waitcomplete() command could help you. It will wait for one operation to stop, before the next one starts.

Good luck

Hi,

I know this post is old but had the same problem and fixed it.  I was trying to send commands that interfered with the measurement before it was done.

As GuentherS said above the waitcomplete() command helped me. After sending the smua.trigger.initiate() command I used the waitcomplete() before doing the next command whihc let the 2602A finish the sweep.

Hope that helps somebody!
