For two tone alignments and power measurements they usually use 400 Hz and 1800 Hz IIRC. Just do not use two tones that are harmonically related.
I have some SG apps on my phone. Don't know about 2 tones though.
Interesting . . . why is that?
The harmonics of the lower tone will add to or subtract from the amplitude of the higher tone depending on phase. This will screw up your amplitude adjustments.
C.K., YOU ARE THE MAN!!!! This is why you are thruly one of my favorites here on the WWRF. I always like the way you can explain things to people who dont understand and ask and you explain it so they understand without taking jabbs or calling someone stupid or an idiot and this is how it should always be NOBODY SHOULD FEEL STUPID OR ASHAMED / AFFRAID TO ASK ANY QUESTION!! This is how everyone learns and thats what we are all here for. my friend
