QA40x Release 1.181

do the number look reasonable?

For the QA402, probably. The QA403 is quite a bit better. You have exported the notch it looks like. Can you try the measurement outlined at the link below? You have the output set to -0.3 dBV, which when balanced, would be 5.7 dBV. And then you’d have 26 dB of passband notch gain. So, you’d not use any user weighting, and enter your 0 dBr point at 31.7 dBV.

And then add a THD+N dBR
