This is a long shot, but I figured I might as well ask!
Anyone have access to a spectrum analyzer? 
There is a ton of noise on my current board and I am trying to figure out what frequencies I need to filter the most. It should mostly be in the sub 5MHz range.

I’ve got a reliable USB model. FFT spectum analysis, decent detail, SNR, SINAD, THD, Bode Plot, etc. Nothing spectacular, but works for me. It’ll get up to 5MHz.
Haven’t tried it, but folks can turn their rigol scopes into an analyzer using the FFT output and python script (via USB) http://hackaday.com/2012/10/10/giving-the-rygol-ds1052e-scope-a-spectrum-analyzer/

I have 3 HackRF Blues. You can borrow one or more of them.

There’s a hack rf at the hive in the drawers under the bench where prototyping, evaluation kits, and eprom burners live.
