Fast Power
Fast power is a faster method of measuring code domain power. A
number of internal values must be transferred from a non-fast power
measurement before fast measurements begin, or when changes to any
of the following fields occur: Data Rate, PN Offset, CDMA TB, Synth
Ref.
The Fast Power Synchronize measurement is designed to set these
internal variables.
The number of measurement averages can be entered in the Num Avgs
field on the FP Setup menu. This number is used to calculate and
display successive code domain power measurements.

Code Domain Power & Noise
The Power & Noise option displays the Code Domain channels along
with channel noise, shown as hatch marks within each channel area.
Noise and power are combined in supplemental channels to take into
account the relationship between channel width and noise power. For
example, a supplemental channel with a width of 2, in which each
individual channel has a noise power value of -15 dBm, will have a
combined noise power value of -12 dBm, or an increase of roughly 3 dB.
