VISION UNIT Menu / VF GAIN
Parameter Remark
CONTROL MODE
Selection of the VF gain control mode
(SYNC / WHITEALL / TESTLINE /
MANUAL)
ON GAIN CONTROL FAIL
Selection for the gain control fail
handling:
AUTO - in case the control mode fails to
work properly the transmitter tries to
recover the signal by modifying the gain.
MANUAL - There is a plausibility check
for the white/sync ratio. The white/sync
values are adapted as needed to regain
a useful signal. If however the control
fails, the transmitter switches to the
manual mode in the end.
