Re: [casper] casper Digest, Vol 75, Issue 8
Hi Dan and all This looks very cool. There is something in the specs I don't understand: * Analog signal: 50 ohm single-ended configurable as three of: o 4 inputs at 250 Msps o 2 inputs at 500 Msps o 1 input at 1 Gsps How many analog inputs are there to feed the ADC's? 12? And some of them come in on the ZDOC connector? How many on board? Sorry if the answer is obvious, I didn't find the answer myself.
