6.3 Function Details
6-7
[3] Wanted
Is the ratio between Output Level and W-CDMA modulation wave
power. This value is correct without a warning message "Power Un-
der 0 dB" displayed.
W-CDMA modulation wave power = Output Level + Wanted
[4] Noise
Is the ratio between Output Level and noise power within 3.84 MHz
bandwidth. This is not the ratio for power of all bands. The differ-
ence between this value and the display value for Wanted is the same
as the setting value for C/N.
Note the following points when using the AWGN internal adder function:
• When AWGN is set to On, the noise power and W-CDMA modulation
wave power are set to match the setting value for RF Level. When
AWGN is set to Off, W-CDMA modulation wave power is set to match
the setting value for RF Level. For this reason, the transmission
power for W-CDMA modulation wave changes when AWGN is switched
between On and Off.
• Setting values such as for C/N and the display value such as for Wanted
become correct only when the total level for W-CDMA multiplex
channels is 0 dB. Use the AWGN internal adder function under
conditions whereby a warning message "Power Under 0 dB" is not
displayed.
