Adjusting Code Domain Power
The tasks in this procedure build upon the previous procedure. This procedure teaches you how to perform
the following tasks:
• “Scaling to 0 dB” on page 581
• “Setting Equal Channel Powers” on page 582
Scaling to 0 dB
After changing the relative power level for a channel, the ESG automatically scales the total power to 0 dB,
while preserving the relative channel power levels. Although the displayed total power changes in value as
channel powers are adjusted, the actual total power is maintained at 0 dB. The displayed channel power
levels remain unchanged, reflecting only user-assigned values, so the user can complete the relative power
adjustments. This task teaches you how to update the display to show the normalized relative channel power
for each channel after completing the setup.
