My AD2 gets a "No Device Detected" from Waveforms. It was working fine until I didn't disconnect the scope and wave gen from tube amplifier before powering down the amp. I tried the AD2 on a windows box and linux box and with different cables and in all cases the get the no device detected. Is there a reset switch or circuit protection switch I can do to get the AD2 working?
Hi @ad2user2019
If you want to troubleshoot the device, you could verify the ferrite beads are ok.
You should measure about zero ohm when the device is unpowered, and about 5V between VBUS and GND when connected to USB.
The next to verify would be the USB controller power rails.
Analog supply switch, IC20, when the device is detected but you get error during connection to the device.
Internal rails, in case the oscilloscope reading and/or AWG outputs are wrong:
