In NI-RFmx, when you switch from some other personality measurements to Demod measurements, it results in a higher EVM on PXIe-5668.
In 5668R, LO frequency settling does not happen as expected when there is a configuration switch from higher IF Filter (320M/765M) with frequency settling of 0.1 PPM, to Lower IF Filter (5 M) with frequency settling of 0.001 PPM.
Workaround: Call NI-RFmx Abort before initiating Demod measurements.
