Well, none of the board I saw there can handle the voltage range we're required to support. Here's the gain table from the hardware we're replacing: Index +/- voltage 0 INVALID 1 10.24V 2 5.12V 3 2.56V 4 1.28V 5 640mV 6 320mV 7 160mV 8 80mV 9 40mV 10 20mV 11 10mV 12 5mV 13 2.5mV 14 INVALID 15 INVALID We don't need to be precise, and not all are truly needed, but the +/-10.24V and +/-10mV ranges are critical to our customer, so both must be supported (or at least as close as we can get, like +/-10V will do, if it must). > You may also be able to use the TS-7800 high res timer to measure the > exact time your sample was taken and interpolate to get the value of > th e reading for the time you want. Don't wait on the timer, just read it. That'd be great, except we need the timer so that we can wait for a short period in order to allow the hardware to do its job after we tell it what to do. __._,_.___
