1
Connect the test point probe to the forward output test point.
2
Consult the design print to find the proper output tilt.
3
Measure the output signal levels at the frequencies you used in To Verify the
Forward Input Level (on page 3-3).
Forward Input Level (on page 3-3).
4
To determine the actual output tilt, calculate the difference (in dB) between
the levels of the lowest and highest specified frequencies.
the levels of the lowest and highest specified frequencies.
5 Proceed
to To Set Up the Output Tilt (on page 3-5).
To Set Up the Output Tilt
862 MHz Equalizers
The forward output tilt can be adjusted using the Forward Equalizer (EQ). Each EQ
has a range of values. Each EQ value is set by installing the corresponding attenuator
pad value. There are three forward EQ’s for the 862 MHz Platform: 0 dB to 4 dB,
P/N 4034450; 5 dB to 9 dB, P/N 4034451; and 10dB to 14dB, P/N 4034452. See the
table below for the full range of configurations for the 862 MHz EQs.
