Setting the Pass/Fail Limits
The measurement limits settings allow you to alter the values of a range of upper
and lower test limits. All of these settings, with the exception of Channel Scanner
Power, affect the metrics color display: red represents fail, green represents pass.
You can switch each measurement limit On or Off independently of all other limits.
If one or more measurement limits is turned On, and they all pass, the summary text
“ALL PASS” is displayed below the numerical results of the screen. If any limit test
fails, the summary text “FAILURE” is displayed in the same area.
NOTE A pass or fail of the Channel Scanner Power Limit does not affect the summary
status.

Setting Channel Scanner Power Limits
You can set upper and lower Channel Scan Power Limits to determine which of the
channels scanned are valid. Channels whose power falls within your specified limits
are displayed in green on your graphics display, and are further indicated with a “P”
for “Pass”. Channels whose power either falls below the lower limit, or exceeds the
upper limit, are displayed in red on your graphics display, and are indicated with an
“F” for “Fail”. A pass or fail of this Channel Scanner Power Limit does not affect
the summary status message. If Channel Power Limits are set to Off, the channels
are displayed in blue on the screen, and no Pass/Fail indicator is shown.
If Chan Scan Pwr Limits are set to On, the limits you specified are represented on
the graphics display with two yellow lines. The High Limit line is indicated with
“H>”, and the Low Limit line with “<L”.
