3.5.2 Analog Notch Filter
The analog notch filter selection affects how the module attenuates the input signal at the
specified frequency. It also affects the update time of the input data which is reflected in
the minimum real time sample (RTS) rate that is available.

One setting applies to all channels in the module.
Value Units: NA
Value Limits: 1-7 (see Table 3-3 above)
3.5.3 RTS (Real Time Sample)
This parameter instructs the module how often to scan its input channels and obtain new
sampled data. After the channels are scanned, the module broadcasts that data over the
backplane.
Value Units: Milliseconds
Value Limits: 21-10,000 for IE2CH or 33 – 10,000 for IE4CH, actual minimum allowed
is based upon Module Filter selection Each module Filter selection will limit the
minimum value allowed, see Table 3-3.
