♦ SCXI-1120 Filter Jumpers
Two-stage filtering is also available on your SCXI-1120 module. The
first stage is located in the isolated section of the input channel,
whereas the second stage is located in the nonisolated section of your
input channel. Two-stage filtering eliminates the noise generated by
the isolation amplifier, producing a higher signal-to-noise ratio.
Furthermore, two filter bandwidths are available, 10 kHz and 4 Hz.
