Same here, but then again, the 400 Hz is the maximum needed to get the full analog voltage. So no problem here.
The C11 board really needs a frequency, the pulse width is of very little influence on the voltage. >>> Geert >> I checked the siggen setup on my test system and 480Hz was the highest >> frequency I could get.
