Equivalent Input Noise Measurements

[koerschgen]

Hi, great Forum, first Post...
Couldn't find anything about the EIN topic.
Is it possible to measure the EIN of a Micpre with REW?
Any help is much appreciated!

Thanks,
Tilmann

Yes, you can read the levels on the RTA, there is a figure in the levels panel for the unweighted rms input level in the 22 Hz to 22 kHz bandwidth. The preamp input should be suitable terminated, usually with 150 ohm.
