CDMA Digital Modulation
cdma2000 Forward Link Modulation for Receiver Test
The power level displayed for each channel is now changed to show the normalized relative channel power.
Figure 10-11 shows the displayed power levels before and after the
Scale to 0 dB softkey is pressed.

Setting Equal Channel Powers
This task teaches you how to set the relative power level for all active channels to be equal, for a total power
level of 0 dB. The normalized relative power level of each channel depends on the number of active
channels. This task is an alternative to scaling to 0 dB.
Press
Adjust Code Domain Power > Equal Powers.
All active channels have now been set to equal powers. Figure 10-12 shows the displayed normalized
relative power levels after the
Equal Powers softkey is pressed with seven active channels.

Managing Noise
The tasks in this procedure build upon the previous procedure.
The following tasks teach you how to set the overall carrier-to-noise (C/N) ratio for the forward link
cdma2000 setup and to set the EbNo value for individual physical channels.
