Issue Details

I'm trying to use Calibration Executive to calibrate a PXI-4461. During the warm-up step, I receive the following error: 

Error -200112 occurred at DAQmx Initialize External 3390001.

Possible reason(s):
Calibration handle is invalid.
Open a calibration session to get a valid calibration handle. Use the valid calibration handle obtained when the calibration session was opened.

The error is caused by a bug reported on CAR 1149063. The error will affect both the PXI-4461 and the PXI-4462. To resolve the issue, install NI-DAQmx 20.7  as the bug fix is included in this version.
