Hi everyone  
I’ve been using gnuradio for six months now, I wanted to ask if its  
possible to interface a signal hound spectrum analyzer to work as a USRP  
with gnuradio. Thanks

If it has an open API to the driver (and it looks like it does from a  
very quick glance), then yes, you can interface it with GNU Radio.  
You’d have to build your own wrapper for it (i.e., gr-spectrumhound).
