actually where can I find the material to sweep it with is what I really meant there.
There are probably a couple of ways to do this. One would be to find some recorded test tones that you could burn to cd to play while you measure and record manually. I have not done this, but I think a couple of other people here have.
The other way is to use a program called REW which has a tone generator built in and is able to automatically record sweeps it generates using an spl meter connected through the computer and receiver.
REW will initially be more difficult as there is some setup involved in connecting all the bits and a little bit of a learning curve to calibrate everything. Once its all set up though, it is dead simple to run.
REW can be found here,
