Audible 9kHz noise

Open wonkoderverstaendige opened this issue 10 years ago • 2 comments

Our acquisition board (v2.1, board 39) is emitting a very annoying high pitched tone once initiated from the GUI. It doesn't depend on the connected headstages, as far as I can tell, but slightly changes in frequency and amplitude when you start the acquisition, but won't stop afterwards unless you disconnect the power plug.

Waving the microphone over the board hasn't given me an exact source yet, but I could try to do so in a more systematic manner if needed.
