The instrumentation amplifier on the SCXI-1100 board fulfills two purposes. The PGIA converts a differential input signal into a single-ended signal with respect to the SCXI-1100 ground for input common-mode signal rejection. With this conversion, the module can extract the input analog signal from a common-mode voltage or noise before the data acquisition board samples and converts the signal. The instrumentation amplifier also amplifies and conditions an
input signal, which results in an increase in measurement resolution and accuracy. Furthermore, software-selectable gains of 1, 2, 5, 10, 20, 50, 100, 200, 1,000, and 2,000 are available through the SCXI-1100 instrumentation amplifier. The instrumentation amplifier is made up of two
cascaded stages with independent gain control as described in Chapter 5, Programming. The first stage has gains of 1, 10, and 100 and the second stage has gains of 1, 2, 5, 10, and 20. The choice of first-stage and second-stage gains affects the settling time of the PGIA. For example, to achieve a settling time of 5.6 ?s at an overall gain of 100, you must set the first and second stages to 10 and 10 and not to 100 and 1.
