I am interested in getting a PCI MAX 3000+

I use Breakaway Broadcast as my sound processor

I want to use the PCI MAX's on-board sound card to have direct digital audio streaming with reduced noise.
But

How or where do I obtain an audio output to do the Tilt Correction test using 60hz Square Wave.

I have Oscilloscopes, two of these actualy...

I also have some qualifications in electronics engineering

Thanks in advance.
