PXIe 5830 Signal Generation with Spurs

[qingjie1908]

Hi guys,

I'm using VST5830 to generate a signal and analyze it by connecting a cable between IF port0 and IF port1. If I use the NI RFSG software panel to generate a 10dBm, 7125MHz signal from IF port0 and use the NI RFmx software panel to analyze it from IF port1, I find that the signal has lots of unwanted spurs. Is there any setting I could use to reduce or prevent them?

Thank you for your time and consideration in advance.😊

Have you tried applying filters?
