If the test results are not what you expected
If the test results are not what you expected, it could be because of one of the
following:
CAUTION
Do not exceed the specified power input limit for the analyzer.
•I The input signal was not connected.
l Ensure that the signal is present at the analyzer input.
l Ensure that the coupler connections and rear-panel connections are
made. See Chapter 2 for more information.
l Ensure proper test signals, line location and field number were specified
for the Option 107 required tests.
q The input signal is too low to be measured.
l If the input signal is too low, use a preamplifier to boost the input signal
(ensure that the voltage and power of the input signal does not exceed
the specified input limits for the analyzer). See “Cable TV Measurement
Specifications and Characteristics” in Chapter 9 for more information
about the minimum carrier level needed.
q The wrong tune configuration was selected.
l Ensure that the correct tune configuration has been selected.
KI
The external pad function was selected, but an external pad was not used
l If you are not using an external pad, ensure that EXT PAD YES NO
softkey label has NO underlined. See “Step 1. Configure the test
