Here is an IQ plot application, tune a transponder (ie using tune-s2) then run this app and you'll get a constellation plot output. You *can* run the app while a tp is attempting to tune but honestly the stv0900 jumps around so fast trying various attributes that almost certainly you wont get usable data from it.

This is an example of an 8psk plot, my cband dish is pretty small so the signal isnt very clean, but gives you an idea.

here is the link to the src for the app as well as the required kernel patch's
