Channel Signal Processing
Parameters The channel signal processing parameters determine the signal processing that
will be performed on the input signals. Use these parameters to select the
output data units and the low cutoff frequency for each channel. There are two
instances of the signal processing parameters, one for each channel.
Full Scale The maximum signal level expected to be processed
by the channel. This value is used to determine the
programmable gain settings across each stage of the
channel’s analog signal processing circuit. Volt
Important: See Appendix D for further
guidance and recommended Full Scale
value settings.
Auto Full Scale (XM Serial
Configuration Utility only) Calculates a new Full Scale value based upon the
current input signal level. Enter a safety factor value greater
than or equal to 1.0.
The safety factor is a number that will
be multiplied to the current signal
level to determine the new Full Scale
setting.
