I accept that, also that it's correct. So anything above my ADC's 0dbfs level (around 1.339v) will be shown as +dbfs I did know that...

Hi... A ran some test, to try the two different calibration techniques out. All test is with Victors 998Hz oscillator @ 2.1V sine. The...

This is really great... After some hour's with trial and error I finally got it right. (Notch is dual fliege OPA1662) This is the way...

Yes... this is excatly how I use my passive notch ----> My other thread regarding passive notch This methoed is working as expected. I...

Great... So you suggest me to try it out adjusted so that the TOP of the notch (away from the notch) is adjusted to 0 SPL instead? -...

Hi here... As I said, proberly need to have some more cleared out. I created a "mic. calibration" / notch compensation file, as...

So this is solved now :) Allway's help John, thanks... Tried to do a couple of 4M / 48kHz sweep's... Notch is >70dB deep I will...

Will do for sure...

Perfect.... Thank's John.

When making your cal file bear in mind the notch centre will have some drift with temperature.

Is it the Decimate IR checkbox. Sry. I'am not knowing that much about that YET :T

Okay... That's something I did not know. I will post back with my findings. Jesper.

Hi trobbins. I did try to lower the span to 900Hz ---> 1100Hz, giving the same result. I tried to step through the notch with RTA / FFT...

Hi here. I'am trying to measure an active 998Hz notch, where the notch deep is around -70dB (very sharp). If i'am measuring it with the...
