PCI-9524 ADLINK Technology Inc.

PCI-9524 is programmed to have 400-µs default settling time, and

this works best with low impedance transducers, such as 120 or

350-ohm load-cells. Insufficient settling time may causes inter-

channel crosstalk; the new signal will not be able to fully settle to

its final value, and some 'residual' signals in the previous mea-

surement will be present in the current measurement. Users may

increase the hardware settling time, to check if a lesser inter-chan-

nel crosstalk is perceived. See Table 4-1 for the equivalent Data

Rates versus ADC actual Sampling Rates, under different operat-

ing modes.
