Crosstalk
Crosstalk is defined here as the influence of one channel upon another when scanning two channels at the specified
per channel rate for a total of 50000 samples. A full scale 100Hz triangle wave is input on Channel 1. Channel 0
is tied to Analog Ground at the 100 pin user connector. The table below summarizes the influence of Channel 1
on Channel 0 and does not include the effects of noise.

System dependent. Using the Universal Library programmed output
function (cbAout) in a loop, in Visual Basic, a typical update rate of
400Khz can be expected on a 300MHz Pentium II based PC.
