Subject: Re: 60MS/sec- is this possible? From: "Lewis Drake" <[EMAIL PROTECTED]> Date: Wed, 11 Feb 2004 10:30:23 -0500
Three different units are being measured simultaneously, which is why 3boards are necessary (they don't all start or stop at the same time, but they could all be on at the same time).
Why not use one board continuously acquiring data on 6 channels an 10MB/s and just discard the data not needed (i.e. when a unit is not active)?
Because I forgot to mention that each unit being tested can be measured at different sampling rates (as silly as this may sound, this is what they wanted).
And Mike Ross asks:
What could possibly be the point of taking data at 10 MS/s and then averaging it down to 2 seconds?
Well, they're expecting very large peaks on the order of microseconds and they were afraid that too low a sampling rate would miss the true peak.
Anyway, thank you to all who replied. The upshot is that they may decide that 50 kHz is enough. Nonetheless, I think it's interesting to think about the ramifications of having hardware that can sample at 100 MS/s but not necessarily have computers that can handle that much data for more than a couple channels....
