FBS Dynamic Filters Tab
This tab contains the fifteen dynamic filters, with a scroll bar to display filters hidden due
to window size.
Dynamic filters are notch filters that are cut only, providing attenuation up to 30 dB at
the specified Q. The default Q is set in the menu, but can be changed on
Tools | Options
the settings tab prior to engaging the FBS dynamic filters. Changing the Q setting after
dynamic filters have been generated will clear all dynamic filters.

Frequency and cut values are read only. Dynamic filters are in auto-detect mode when the
FBS block is active (when Bypass FBS is off). If testing reaches a point where no further
changes are desired, the lock button may be engaged. The lock mode of operation is
temporary, and is intended to be used during setup of the FBS. When the FBS dialog
window is closed, lock mode is automatically disengaged.
If there are specific dynamic filters the operator wants to assure are not overwritten, press
the button to write the designated filter settings to the first available filter
