Balancing the Reverse Path
If yes, proceed to step 5.
If the output level is more than the design output level, replace the reverse
output pad with a higher value pad.
If the output level is less than the design level, replace the reverse output pad
with a lower value pad.
4 Repeat steps 2 and 3 until the output level is correct.
5 Remove the test probe from the reverse output test point, leaving other
5 Remove the test probe from the reverse output test point, leaving other
equipment connectors intact.
To Set Up the Equalizer Values for Reverse Path
42 MHz Platform
The reverse output tilt can be adjusted using the Reverse Equalizer (EQ). Each EQ
The reverse output tilt can be adjusted using the Reverse Equalizer (EQ). Each EQ
has a range of values. The EQ value is set by installing the corresponding attenuator
pad. There are two types of reverse EQs for the 42 MHz Platform: 0 dB to 5 dB, P/N
4034465; 6 dB to 10 dB, P/N 4034466. See the table below for the full range of
configurations for the 42 MHz Platform EQs.
