You can use the Limits settings to set pass and fail limits for several measurements.
With the Limits setting for a measurement set to Off, the measurement result is
displayed in black in the Metrics portion of the screen.
Setting the limits On for your selected measurement can affect the way the result is
displayed. If the measurement result falls within the bounds set by your limits
settings, the numeric result is displayed in green, and “(P)” is displayed beside the
result If the measurement result falls outside the bounds set by your limits settings,
the numeric result is displayed in red, and “(F)” is displayed beside the result.
In addition, the words “ALL PASS” (in green) or “FAILURE” (in red) are displayed
in the bar at the bottom of the screen. This message refers to all limits which have
been turned on. In other words, if one or more of the results for which limits have
been set to On has failed, then the “FAILED” message is displayed; the “All PASS”
message is displayed only if all measurements have passed their limits tests.
NOTE No summary “All PASS” or “FAIL” messages are displayed if either of the Pilot
Dominance or the Multipath Power limits are not being met.
If the OTA PN Scanner is turned On, and either the Pilot Dominance Limit is not
being met, or the Multipath Power Limit is not being met, all metrics will be
displayed in gray text. This indicates that because either one, or both, of Pilot
Dominance and Multipath Power have not met their specified limits, all the results
being displayed are inaccurate to an unknown degree, and are therefore unreliable.
Ensure that your signal meets the Pilot Dominance Limit and the Multipath Power
Limit to ensure you collect accurate results.
Regardless of your limits settings, no indication of a pass or a fail for individual
measurements is given if
CDP and Metrics are turned Off (see “Metrics Provided
by the 1xEV-DO Tx and Over Air Analyzer Measurement” on page 104).
Similarly, the “ALL PASS” or “FAILURE” messages are not displayed if
CDP and
Metrics
are switched Off. The single exception to this rule is the Time Offset
