The best way to prepare a threshold file is to start with a working sample. Contact Spirent to obtain a
sample.
You should never change a threshold name (first field), otherwise the threshold will become
unrecognizable and the unit will use a default instead.
If any value exceeds a theoretical limitation, the unit will reset it to a valid value. For example, if a
percentage value exceeds 100, it will be reset to 100 upon import. For fields that inherently require a
theoretical minimum or maximum, you can specify two hyphens (--) instead of an explicit value.
You can precede any line with an exclamation point (!) to restrict the setting from editing onboard the
unit, for example:
!Pass Loss Degradation (%),--,25,Yes
In this case, the threshold range will be viewable on the unit, but will not be editable. Note that this
condition cannot be undone except by importing another thresholds file to the unit.
5.6.4 Video > Video Monitor
The Video Monitor feature allows the unit to serve as a basic video display monitor, similar to a
television that is connected to an STB. The primary purpose of this feature is to allow video and STB
verification in the absence of an actual television; however, it may also be used for any situation where a
monitor is required for an analog video feed.
Using a required dongle, the unit accepts a simple analog video signal as provided by tuning devices
such as STBs, DVD players, etc. The dongle must be ordered from Spirent and should be connected as
follows:

With the dongle properly connected and a video signal active, the video should begin to display as soon
as you select Video Monitor. Note the following:
