The first screen that will appear is a tabular list that includes the video
and audio carrier levels along with the delta V/A for each channel.
Use the up and down arrows to scroll through the list. Indicators
appear within the list to flag out-of-limit conditions. The following
table relates each indicator with its meaning:
* adjacent channel limit violation (does not apply
to digital channels)
↑
over limit violation
↓
under limit violation
> over range measurement error
< under range measurement error
E unlocked measurement error
To view the data for the channel highlighted in the list press the
soft key or the key. Use the PASS/FAIL indicator to quickly
determine whether the channel has passed the limits check. If the
channel failed, you can identify the reason(s) for the failure by looking
at the symbols that appear in this indicator.
Press the soft key or the key again to scroll to the limit
check summary. To quickly determine the status of the overall limit
check, look at the PASS/FAIL indicator located in the upper portion
of the screen. This indicates FAIL if any channel is not within the
required limits. For each limit, the worst case value is displayed along
with a pass/fail status. You may have to scroll down the list to see all
the limits results.
