Close full duty cycle (93% in attached images) the DMC60 pulses through zero to -12V and upon trying to recover causes an over voltage failure on the power supply. This happens unloaded and with a small load of 4Amps. Anyone else have this issue? Cheers, matt The onset of this behavior can be seen as you increase the duty cycle you get an occasional incorrect extra pulse as shown in the following figure
My trusty AD 1 seems to have developed a fault. If I connect the AD to the USB and run Waveforms and use the spectrum view I see some peaks at 13.02kHz, 26.04kHz, 39.06kHz on channel 2 that are not present on channel 1 and are not present on a different AD unit that I have. The units are both Rev C. Take a look at the attached screen capture. There is another peak at 52kHz but this is down in the noise. I have also noticed that if I generate a signal on the AWG2 with no external connections, say 50kHz, this then appears on the spectrum of the channel 2 input. If I do the same with AWG1, t
