The monitor’s built in Alarm system allows for simplified QC monitoring of signals with minimal overlap of active
video. The alarm monitoring system allows you to specify alarm parameters that will trigger onscreen and/or re-
motely monitored warnings when a specified condition is met and provide an unobtrusive QC viewing mode com-
pared to having onscreen scopes active at all times. Please note the alarm monitoring capabilities are limited by
the processing power of the monitor.
The signal will be sampled at a variable rate depending on other processing
loads placed on the monitor. With minimal additional processing demands the fastest sample rate is approxi-
mately every 2 to 3 frames. It is therefore possible that an alarm event occurring for only 1 or 2 frames may be
missed by the alarm monitoring system. The alarm monitoring system is a useful tool for quick analysis of content
to make sure no serious errors exist, but it should not be used as substitute for standalone legalizers and signal
level monitoring systems in ultra-critical level monitoring applications.
Alarm Menu Functions
Alarm
Selects the type of alarm events that will be monitored. This selection ONLY affects onscreen (visual) alarms
and does not change what alarm events can be monitored through the remote control alarm monitoring soft-
ware.
Safety Alarm: Will trigger an alarm if a loss of signal is detected, a full black field is detected, a full
blue field is detected, and/or embedded audio goes mute for the amount of time specified in the Au-
dio Trigger Time setting. The audio mute alarm will only trigger if audio is being embedded into the
signal and is mute for the specified amount of time, there will be no audio mute warning if audio is not
being embedded into the SDI signal.
Safety Video Alarm: Same as Safety Alarm minus audio alarms.
IRE Alarm: Will trigger an alarm if the IRE level specified in the IRE Trigger Level setting is exceeded.
RGB Alarm: Will trigger an alarm if any RGB Levels exceed 100IRE.
IRE & RGB Alarm: Combines IRE and RGB Alarms and will trigger an alarm if either or both exceed
their set parameters.
All Alarms: Will trigger an alarm if any alarm condition is met (Loss of Signal, Black Field, Blue Field,
Audio Mute, IRE threshold exceeded, RGB levels over 100IRE).
Visual Alarm
When set to ON a small box will appear on the monitor’s screen whenever the
alarm condition set in the Alarm menu selection explained above is triggered.

*NOTE: Onscreen Alarms are proc-
essing power intensive. When active
the monitor may respond more
slowly to user input via buttons/
remote control if a large number of
successive alarm events are occur-
ring. Switching to an unused input
with no video will allow the monitor
to respond quickly to user input
should the operator simply want to
turn Alarm monitoring off in scenar-
ios where monitor menu response is
slowed by such successive alarm
events.
