Solution
This is an expected behavior as under Analysis mode, the RFmx WLAN EVM measurement does not goes through any hardware settings. Hence, we would need to perform the following actions:
- When saving the waveform using the RFmx Waveform Creator, enabled the AWGN and introduce a Sample Clock Offset in the Impairments section.
- In the LabVIEW VI, add in the Configure Common Clock Source Enabled VI and disable it.
By doing the above, the EVM can be measured correctly.
