Acceleration Frequency Response
The following table represents the frequency ranges for the 3500/42 under
different filtering options. Resources used for filtering are assigned based
on channel pairs. It is possible to select different filtering options for the two
channels of a channel pair. However, the frequency response for both
channels will be limited to the worst case frequency response of the
individual channels. If added frequency range is required, the 3500/42 can
be configured as a two-channel monitor (use channels 1 and 3). This lets
you combine the resources normally used for filtering of two channels and
use them for one. See page 48
