Hi all,
Cool Edit can be used to generate white noise and mix it with
your test signal at a desired S/N. Or you can record "real" noise
off the air and mix it in desired ratio with signal. And it can
do FFT analyses, measure RMS power, generate interfering tones, etc.
It lives up to its name! http://www.syntrillium.com
I have no connection with Syntrillium - just a satisfied customer.

... look for a shareware called Cool Edit 2000, it comes with limited
features unless you pay for it, but it will do what you plan. It is a very
good graphic type editing file for all kinds of audio files. I use a
(licensed) copy to edit the music files we create (see www.piperswine.de
-hi-), but also for exactly what you plan to do, sending WAV BPSK files in
a loop.
