What are you thoughts on this
I think you are trying to establish the frequencies that cause unwanted vibration in your turntable.

The simplest thing to do is to use the proper soundcard.cal file and use the signal generators 'frequency tracks cursor' feature to test for the worst vibrations.

If you want to make up a microphone.cal file that matches the RIAA curve, you could do that and test an REW sweep up to 200Hz and hope the cartridge is microphony enough to provide an appropriate level to satisfy the input line-in of the soundcard from your preamp. I just don't see how you could use a playing record to get any meaningful data to stop vibrations...
