Agilent 34980A (with 34921A module) returns an incorrect 1st measurement with READ?

Hello all!

 

I'm trying to get to the bottom of an intermittent issue that we've had for a while.  Sometimes, the first measurement returned from a scan does not match the rest of the measurements.  In fact, the measurement looks like it belongs to the previous scan!

 

I have not found what is triggering it.  It is not solely a hardware issue, as it only appears while testing certaint variants of our product.

 

I've already created this thread on the Agilent forums, where a lot of my details are recorded:

I'm using:

LabVIEW 2010

Test Stand 2010 SP1

Visa commands to talk to the Agilent

 

I'm using the Agilent for both switching and measurement functions.

 

I'm sure there are moredetails you need - let me know and I will add pieces of code, settings etc.

 

Thank you!

James
