W-CDMA Uplink Digital Modulation for Receiver Test
Adjusting Code Domain Power
Setting Equal Channel Powers
This task teaches you how to set equal relative power levels for all active channels while
maintaining the code domain power 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.
Both channels have now been set to equal powers. Figure 15-55 shows the displayed
normalized relative power levels after the Equal Powers softkey is pressed with two active
channels. Depending on the entered channel powers, the displayed total power may show a
low residual value (such as 0.02 dB) due to decimal rounding.
