You have now modified the reverse fundamental channel parameters so that the radio
configuration is 4, the data is a fixed 4-bit pattern of 1010, the relative channel power is
−10 dB, and EbNo value is 12 dB. Figure 8-13 shows what the display should look like when
this task is completed.

Note that the ESG allows you to set the relative channel power for each active channel. To
display the normalized relative channel power after completing the setup, it is recommended
that you perform the steps in “Adjusting Code Domain Power” on page 232. Also note that
varying the EbNo value on one channel will affect the EbNo values on all active channels.
Refer to “Managing Noise” on page 234 to learn how to make final noise adjustments.
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 232
• “Setting Equal Channel Powers” on page 233
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. The displayed power levels
