200 ksps ADC documented
Ross Millar, student at the University of Glasgow, has worked for six months at CERN to debug the 200 ksps ADC, write firmware for it and develop a new version of the circuit board.
09-08-2011: Successful Data Acquisition
There has been successful data acquisition on all input channels of the current 100ksps 16bit ADC FMC. The FMC now requires some redesign to ensure its full compliance with the FMC standard, however the current FMC shall be suitable for testing and further developing the firmware.
14-06-2010: Evaluating connector type
We are still looking for the right connector type to use to get ten or more differential channels in. One suggestion is to use the Camera Linkhttp://solutions.3m.com/wps/portal/3M/en_WW/electronics/home/productsandservices/CameraLink/ standard using individually shielded twisted pairs.
