525 – Luma Max Exp.
This measure verifies that the luma content of the
video signal regularly traverses a nearly-white level.
This level is set by the user with the threshold slider.
Enable:
check to enable this test
Threshold:
set the level (in mV) below which this
condition will be flagged
Duration, Occurrence and Interval:
Set up the error
detection window using the sliders.

525 – Freeze
Detect whether selected portions of the video image
are static for a period of time. Four independent
zones are set up and checked, each accessed from
a tab.
Note:
these four zones are common between the
Freeze
and
Black
parameters, so they can be set
up in either panel.
Enable:
check to enable this test
Full Screen:
click this button to set the selected zone
to full screen size.
Start & Stop / Line & Pixel:
define the size of the
zone by identifying it’s top left corner (Start line &
pixel) and bottom right corner (Stop line & pixel).
Note:
you can also set the zone size and position
by clicking the Freeze tab in the display area, and
using your mouse to drag the outline of the zone
Signal Quality:
Select a quality level appropriate to
the signal being monitored, over the range “Noisy” to
“HiQ”, so that the Freeze algorithm will know how to
treat noise when attempting to detect a frozen
image. Some experimentation may be required.
Duration, Occurrence and Interval:
Set up the error
detection window using the sliders.
