equivalent noise level and power supply rejection ratio

[popcorn]

I am using labview 8.2. I wanted to know if there are available power supply rejection ratio vi and equivalent noise level vi. The analysis done is sound pressure from microphones into pxi-4461.

The power supply rejection ratio is not something I am familiar with, but you can look at this link  with example and determine if Common Mode Rejection Ratio is what you are referring to.

As for an equivalent noise level vi, it is a vi that ships with the Sound and Vibration Toolkit (SVT).  Otherwise, it is a vi you will have to write yourself.
