5646R Calibration Execuitve 4.1.1 "Adjust LO Power Sensor" Error

[QV3189]

During adjustment "Adjust LO Power Sensor", Calibration Executive displays a fatal error stating that the program "could not converge upon a single value". The error is repeatable for every VST unit for which the routine is attempted. Suspecting a memory issue, I restarted the controller and initiated an adjust routine immediately after CalExec boot-up. The error is persistent. The VSG cards just returned from MFR cal just a week or two ago, and haven't been used between then and now. 

Here is a list of what I have tried so far:

-Changing cables out one at a time

-Resetting 5611

-Self-test on 5611 passes

Interestingly enough, the 5611 when calibrated separately, fails IQ Impairments portion against our in lab FSU. The errors in question are attached as PNG files.

Any help would be appreciated!

Hello QV3189,

I recommend trying to use a different PXI/PXIe-5611? This may be causing the error.

If this does not solve the issue, I highly recommend that you create an NI service request to troubleshoot this issue. This may result in an RMA for the PXI/PXIe-5611.
