Re: Odd ~17Hz noise in all channels

Hi Coen,

My EEG set-up is composed of 2 sets of 32 electrodes. They are plugged on ports A1-A32 and port B1-B32 of my AD-box. Set A includes pin-type CMS/DRL electrodes. Then, can I let these 2 pin-type electrodes unplugged, and use flat-type CMS/DRL instead ?

Many thanks for your help !

Re: Intermittent Error 5000

Dear Robert, Thank you very much for your reply. I am actually pretty sure that my AD-Box is working well - the LED are always on. There was actually a mistake in my last message (now modified) : i was talking about the USB Receiver, not the AD-box. Indeed, i noticed that when the Error 5000 occurs ...
