Available Features (cdma2000/1xEV-DV)
89601B7NC cdma2000 provides the following cdma2000 and 1xEV-DV signal modulation capabilities:
Digital Demod vs. cdma2000/1xEV-DV features
cdma2000 features
These features are applicable to cdma2000 modulation analysis:
-
Standard presets for
-
cdma2000 Reverse link
-
cdma2000 Forward link
-
-
1.2288 MHz Megahertz: A unit of frequency equal to one million hertz or cycles per second. variable (user definable) chip rate
-
Single code domain layer or composite code domain power and code domain error trace data displays (the composite trace data shows all code layers simultaneously). Code domain power can be normalized to display the code domain power relative to the total signal power in the code domain.
-
Code domain Offsets table which shows time and phase offset of each active Walsh code channel
-
User selectable Walsh code QOF assignment.
-
Optional multi carrier tolerant measurement filter.
-
Variable active channel threshold setting.
-
Single channel time-domain displays, such as IQ measured, IQ reference, IQ magnitude/phase error, and error Vector traces.
-
Composite time-domain displays, such as IQ measured time, IQ reference time, IQ magnitude or phase error, and error vector time traces.
-
Mirrored (flipped) frequency spectrums used to remove the effects of high-side mixing or complex conjugation mismatches in simulated data.
-
Measurement offset and interval (similar to time gating) used to select specific data PCGs for analysis
-
Time gating is not available (does offer measurement offset/interval feature)
-
Averaging is available only for code domain data and is applied to numeric error data in the symbol table, as follows:
-
rms (video) computes an 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.
-
peak hold/continuous peak hold keeps track of the peak rms error of each update in the table.
-
Time and time exponential averaging are not available.
-
-
The following average types are available for the pre-demodulated spectrum result:
-
rms (video)
-
rms exponential
-
peak hold/continuous peak hold
-
1xEV-DV features
These are the additional cdma2000 features that are applicable to 1xEV-DV modulation analysis (
property is selected):-
Automatic modulation scheme detection for F-PDCH channels
-
Automatic active channel identification, and optional predefined F-PDCH active channel configuration for adaptive modulated signals.
Digital Demod vs. cdma2000/1xEV-DV features
-
Features that are applicable to Digital Demod but not available with cdma2000 demodulation:
-
User selectable Measurement/Reference filter.
-
Pulse and Sync search
-
Equalization Filter
-
