The eq in ProChannel has an analyser that shows the eq curve

My last comment I began to ramble a bit (as I often do ) But Mike had a good point about using the PC QCEQ. it wont return pinpoint data but still a great reference.
You did mention you owned Soundfordge and Sony Soundfordge does have a Spectrum Analysis.
(View > Spectrum Analysis, or Alt+8). So if you are H bent on doing some tests, that might be helpful .
Good luck.

I didn't know that - I looked but didn't find anything indicating as being an analyzer...Could you point me in the correct direction?
 
Chuck - I probably should have been more specific...I have the "non-professional" version of Sound Forge (SF Audio Studio v 10)...I didn't see the spectrum analyzer anywhere. 

In Platinum the QuadCurve EQ has a fly-out panel0 with a spectrum analyzer.

 
The new L-Phase EQ in Platinum and Professional has a spectrum analyzer too.

There is also the free VST plugin called SPAN by Voxengo.

Without post processing (or desire not to use it), the curve of a mic may come into play depending on application. But with the slew of post processing available (and cheap), there are not many limits to what audio can be morphed into.

Another test is to record the same thing on two mics simultaneously and EQ match one to the other; but in the end of the day, it is not that a mic cannot hear a frequency, and if present can be adjusted (within reason).

another option - room EQ wizard (REW) - normally used for measuring room acoustics - you can use it to baseline your room (e.g. use a flat mic like an ECM8000 or a better one) to create the "calibration", then using the sweep function, you can test each mic, and use the calibration to eliminate (mostly) the room effects, resulting in the net response of the mic. may be more complex than you need in which case using SPAN, etc would be likely be simpler _but_ you may still be impacted by room response...

fwiw if you have older sonars there's analyst:

not sure why stopped including this? (Pic is from x2 docs)

I keep hassling them about bringing it up to date, I agree it should be included - even for no other reason than the multiband envelope generation.
