2204 AWG
My audio power amp manual says; DC-VOLTAGE PROTECTION CIRCUIT TEST: separately test both pwr amp channels: *drive the pwr amp with a test signal (f=7Hz) and without load, *at an input of approx. 3Vpeak the protection circuit reacts...
How can I achieve 3Vpeak since maximum output of AWG is only 2Vpeak? Please help me. Thank you so much.

Re: 2204 AWG
I used a DC amplifier from aliexpress

It has default a amplification of 33 or so (don't remember exact) changed it to 10x chanting 2 resistors on the board.
works ok til 50kHz.
