Changes to panFFB.db_IN
The following line was changed
feedback PITA onc 1 bcm1 -> feedback PITA on 1 bcm1
but this did not correct feedback.
The following lines were added
feedback IA off 2 bcm1
feedback PZT off 20 bpm4b
and this started feedback working but the timescale for changes was about 8
seconds because we are at 240 Hz.
After the change
feedback PITA on 1 bcm1 -> feedback PITA on 16 bcm1
the timescale for feedback is 2 minuts, as expected.
the configuration at the moment is:
anatype fdbk
curmon bcm1
feedback PITA on 5 bcm1
feedback IA off 2 bcm1
feedback PZT off 20 bpm4b
PITAparam slope -1721
