a pop–up window with print options. The printable copy can be filtered

Alarms can be assigned or removed. The pop–up window may take a

window by checking the desired boxes.
To set a Log Trigger, select a DID/SDID value from the dropdown menu
on the left and then choose a specific event type from the adjacent drop
down menu. One of the following events can be chosen: "Present,"
which triggers when a particular packet is present in the video stream,
"Absent," which triggers when a packet is not present in the video stream,
"Change," when the packet presence changes from being present to
not present or vice versa, and "DataChange," which triggers when the
packet presence remains the same, but the data within the packet has
changed. The events are evaluated on a per–field basis. After select-
ing a value for DID/SDID and Trigger On, click Add to begin logging
occurrences of the Log Trigger.
To set any of the Alarms, click the box to the left of the desired Alarm.
After selecting all Log Triggers and Alarms of interest, click Apply and
then OK to begin logging the selected Log Triggers and Alarms and to
return to the Log Viewer. To disregard the changes made, click Cancel
to return to the Log Viewer.
The available alarms are grouped into three categories: General Alarms,
Caption Pair Alarms and Error Alarms. There are five alarms in the
General Alarms category that can be used to get an overview of possible
problems.
