Spectrum Analyzer USB-SA44B - Peak, frequency & amplitude measurements of RF the signal

[dusl]

Hello

I'm using the Signal Hound USB-SA44B for RF quality measurements of our products.

I need to get basic main measurements like

1. Find the Peak
2. find Main frequency (per found peak)
3. measure Main frequency & amplitude

For instance get measured in the found peak point is: frequency 433.92 MHz and amplitude -21dBm?

Unfortunately manufacturer didn't provide simple examples for measurements.

My development environment:

• LabVIEW 2013

Attached the output graph that I receive during the test

Thanks in advance

Seems like this whitepaper on peak detection might be a good start:

Thank you for reply. Unfortunately your response  was in the spam folder of my mail, and I just today discovered it. I'll try to build provided algorithms, but I expected some working .vi, that was verified  . I tried several peak detection functions and configurations. they recognized the peak, but not automatically showed the time indicator. So I have to build it by my self .

There are also some example VI's bundled with LabVIEW that might do some or all of what you need.

Searching the NI Example Finder within LabVIEW for 'peak' shows a whole bunch of examples that deal with detection and analysis of peaks.

thanks, I'll check
