Issue Details

I generate a WLAN 802.11b/g DSSS waveform by RFmx Waveform Creator for WLAN and load it to RFIC Test Soft Front Panel, but it shows an error "Error: Error -1074097882 occurred at niRFSG Commit.vi".

Solution

We've found this issue happening in RFmx 24.0d137 and RFmx 23Q1.
We're seeing this error since the IQ rate is less than signal bandwidth when default oversampling ratio of 1.25 is used. RD plans to fix it in April 2024 release.

Workaround:
Change the Oversampling Ratio in RFmx Waveform Creator for WLAN from default 1.25 to 4, the error would not show.
