QA402 measurement specifications

I am using the QA402 to take classic audio measurements of a mic preamp I’m designing for a uni project. I was wondering when taking for example a THD measurement the number of harmonics that are being measured? Or when doing THD+N and/or SNR/EIN what is the specified bandwidth of measurement ?
Thanks for the time !

Hi @noeh,

If you control + click (or right click) on the RMS, THD or THDN box, you get the global settings for those measurements

By default, the measurement bandwidth will be 20 to 20K, but you can change it as needed. The measurement stop frequency also specifies the number of harmonics you will capture for THD and THD+N. This is also the place you specify how your fundamental will be determined.


Awesome ! thank you very much !
