I've tested power amplifiers while driving a dummy load in place of a loudspeaker; and preamps, similarly with an appropriate load, the inputs in either case being fed a low distortion signal to which the resulting output is compared (as to frequency response, THD, etc).
My question is, can one test the linearity/distortion characteristics etc of a mic's preamp/impedance converter in a similar way - that is, without the transducer - by substituting ...something... for the capsule, applying a very (very) low-level signal across it, and testing the output?
Am I off-track here...how does one normally do this test? Obviously I mean to take the non-linearity of the capsule out of the equation in order to find out the frequency response and distortion characteristics of the electronics alone.
Thanks for any feedback!
