Changing this name may invalidate existing station configurations.
Connector: Describes the front-panel I/O Carrier connector assigned
to this input.
Application Attribute: Not applicable.
Filter Type: Used to select the type of filter used to filter the digital
output of the DUC. Selections include: Disabled, Bessel, Butterworth,
and Elliptical. (Default=Bessel, 300 Hz.)
Filter: This is the frequency where the filter, selected in the Filter
Type box, attenuates the signal by 3 dB. A setting of zero disables
the filter.

True=enables high-speed data acquisition. The high-speed rate is
determined by the system rate and a number of other factors.

clamp entry is omitted.
• Zero—Clamps the servovalve to zero—if valve balance is used,
it will clamp to this value.
• Positive—Clamps the servovalve to positive 50% spool opening
on a 2-stage valve driver, 50% outer-loop command on the
3-stage valve driver.
• Negative—Clamps the servovalve to negative 50% spool opening
on a 2-stage valve driver, 50% outer-loop command on a 3-stage
valve driver.
