Feature Availability in W-CDMA
Most features which are available with other instrument modes are also available
with W-CDMA analysis, with the following exceptions:
l
You cannot include Wideband CDMA measurement data in math functions.
In addition, when the instrument mode is Wideband CDMA, you cannot display
math functions.
l
Averaging is not available for trace data in W-CDMA but may be applied to
numeric error data in the symbol table. Three types of averaging are available:
– rms (video)—computes an rms average of each rms error update in
the table
– rms exponential—is like rms (video) except that averaging continues past
the average count with an exponential weighting
– continuous peak hold—keeps track of the peak rms error of each update in
the table
Increasing Measurement Speed
Here are some tips for maximizing measurement speed.
l
Use fewer slots
l
Use the smallest frequency span
l
Use cardinal frequency spans
l
Enter the scramble code instead of specifying a scramble-code group.
l
Use the smallest possible value for mx WCDMA span (press [System Utility],
[memory], [
configure meas memory]).
