Good Morning
First post so be gentle , I am slowly trying to learn about electronics and adequate measurements. I bought Pro version while ago mainly to help me with turntable and cartridge setup but I’d like to learn bit more about , so far I have used built in measurements but I bought function generator and oscilloscope. I’m trying to check frequency response but the best I can do is spot frequency check. I’ve tried built in frequency response measurements using linear sine sweep of 300sec from external generator but results are way off my spot test , any way for a step by step instruction how to set it up , I’d like to run frequency response test in the typical 20-30kHz range using external generator .
Probably quite trivial but I got stuck on this

It looks like that you used the preconfigured panel setting "FRswph" to perform the frequency response test. In this method, the signal generator sweeps from 20 to 22050 Hz linearly over 300 seconds. The spectrum analyzer is set to peak hold mode with an FFT size of1024. The following screenshot below shows a loopback test of a sound card using this method.

To run the test, simply click "FRswph" in the second toolbar to load the preconfigured panel setting file, then start the oscilloscope and signal generator. The sweeping process can be observed in real time. After more than 300 seconds, the final frequency response curve will be displayed.

Feel free to upload your test result here so we can help to diagnose the issue.

Thank you for the quick reply, does it apply if I use external generator to do the sweep?
I started using external one as USB card I use seems to have some 50Hz and harmonics and headphone out some 1kHz noise, anyway I need around 1V RMS signal and soundcard is not capable of outputting that much
Thank you again

I've tried again and it works , thank you.
Great software
