Hi Jean-Jacques,
On TP2 I measure a nice sinus with the correct frequencies and also the correct voltage (2.7Vpp).
But on TP1 I measure a nice sinus with the correct frequencies (100Hz, 1kHz, 10kHz) with strange voltages:
100Hz: 1Vpp
1kHz: 2Vpp
10kHz: 300mVpp
I guess the "Overflow" message which I get means that the 2Vpp are too high.
U20 Pin 14:
100Hz - sinus 2.8Vpp - ok
1kHz - sinus 5Vpp - NOT OK
10kHz - DC 1.5V - ok
U20 Pin 1:
100Hz - sinus 2.8Vpp - ok
1kHz - sinus 3Vpp - OK?
10kHz - sinus 800mVpp - OK?
It looks like I have a problem somehow with my filters here.
Best Regards
Benjamin
