Pass/Fail Measurement Indicators
After completing an autotest, to view the measurement results from any location, select the
corresponding Results softkey. The following tests can be executed at each location:
• Channel Plan Scan – This measurement scans each channel in the selected channel
plan and compares the results to the selected limit set. This test includes: Level, Tilt,
C/N, MER, and BER.
• Modem Test – This measurement performs a modem login and compares the results to
the selected limit set. This test includes: Pre/Post Bit Error and Modem Launch Levels.
• Spectrum Test – This measurement performs a return spectrum test and compares the
results to the selected limit set. This test includes: Maximum Ingress Level.
A Pass/Fail status will be displayed at the top of the results screen along with detailed test
results for each test. When any of the individual measurement parameters of a test fail, the test
as a whole will indicate a Fail status.
Each individual test will indicate its status using the following icons:
This icon indicates that this
measurement was skipped. This
only applies to measurements that
are not enabled.
This icon indicates that all of
the measurements for this test
have passed the measurement
thresholds.
This icon indicates that one or
more of the measurements for this
test have failed the measurement thresholds.
