Filter Alpha
This key allows you to enter a filter alpha value for a Nyquist filter or
root Nyquist filter. The entered value appears in the active entry area
of the display. This key appears in several locations.
NOTE The Filter Alpha softkey appears only after you choose a root Nyquist or
Nyquist filter. If a Gaussian filter is used, you will see
Filter BbT. If any
other filter is selected, you will see a
Filter Factor N/A softkey
(grayed-out).
The filter alpha value is set to 0.220 at the factory. This value can be
user-defined. The value is not affected by an instrument preset or by a
power cycle.
Range: 0.000 to 1.000
