Table 7-1: Possible Error Conditions to Produce a Fault

Upon hot-switches, a resulting glitch in the video signal can cause the
AVC-LB to momentarily report a video fault. This menu item allows the
user to set a minimum duration (in frames) during which the AVC-LB will
ignore such glitches and not trigger a fault alert.
