Cisco GainMaker Optoelectronic Node 1GHz with 65 86 MHz Split Installation Guide

To complete the balancing procedure, you will perform the following tasks: 

 

Determine the output tilt. 

 

Set the output tilt. 

 

Set the output level. 

This section provides instructions for performing each of these tasks. 
Note: Before you begin, make sure that you have configured the amplifier module 

according to the specifications in the design print, and that the amplifier has warmed 

up for approximately one hour. 

 

Complete the following steps to determine the output tilt of the amplifier. 
1  Connect the test point adapter to the Port 1 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 

Input Signal Level. 

4  To determine the actual output tilt, calculate the difference (in dB) between the 

levels of the lowest and highest specified frequencies. 

5  Proceed to the next section, To Set the Output Tilt. 

 

Equalizers (EQs) are available in 1.5 dB increments. A 1.5 dB change in value 

changes the difference between low and high frequencies by approximately 1 dB. 

 

Increasing the FWD I/S equalizer value reduces the level at lower frequencies,
