I am using NI PXIe-5668 Vector Signal Analyzer to perform EVM and ACLR measurements using 5G NR and LTE profiles. I am able to execute the measurements through LabVIEW examples but the NI-RFmx Soft Front Panel is not loading. I do not get any error but the Soft Front Panel window just doesn't open. As a result, we are unable to manually debug and check/arrive at the settings necessary.
There can be many possible reasons for the NI-RFmx Soft Front Panel not able to launch. You can refer to the below troubleshooting steps to see if these resolve your issue:1 - If you are trying to launch the NI-RFmx Soft Front Panel from NI-MAX, you could instead try launching it from Start»All Programs»National Instruments»RFmx Soft Front Panel. If you are able to successfully launch it from here then NI-MAX could have some issue and an NI-MAX repair might help to resolve this.2 - This could be caused by incompatibilities between different RFmx driver components installed on your system. To verify this you could run the Version Compatibility Checker utility located at <NIDir>\RFmx\niRFmxCompatibility_Checker.exe & see whether any incompatibilities are reported.3 - If you are logging into a Windows PXI(e) controller remotely via VNC or Windows Remote Desktop, please check whether there is a display monitor connected to the controller & whether it is switched ON. If a display monitor is connected and is switched OFF, then the RFmx Soft Front Panel might be automatically loading onto it. Powering ON the display monitor or disconnecting it might solve the issue.4 - If none of the above steps solves the issue then the NI-RFmx drivers might have gone corrupted. Try repairing NI-RFmx components using NI Package Manager.
