5 CDMA2000 Measurements
The "CDMA2000 TX Measurement" (option R&S CMW-KM800) provides quick and
flexible TX tests on CDMA2000 reverse link signals. The tests cover the following MS
transmitter properties:
●
MS output power, channel power
●
Modulation accuracy (EVM, phase error, magnitude error, frequency error, transmit
time error, I/Q imbalance and waveform quality)
●
Spectrum emissions (adjacent channel power, occupied bandwidth)
●
Code Domain Power (CDP), Code Domain Error (CDE)
●
Channel phase offset and channel time offset
●
Open Loop Time Response (OLTR)
Many of the tests and conformance requirements are specified in 3GPP2 C.S0011,
"Recommended Minimum Performance Standards for cdma2000 Spread Spectrum
Mobile Stations".
Transmitting a well-defined forward signal to the AT facilitates many reverse link mea-
surement tasks. To generate modulated RF signals, the R&S
CMW must be equipped
with the ARB and real time baseband generator module. The following option enables
processing of CDMA2000 waveform files:

5.1 What's New in this Revision
This revision describes version 3.5.10 and later of the "CDMA2000 Measurements"
firmware application. Compared to the version 3.2.80, it provides the IQ offset compen-
sated IQ diagram, see
Multi Evaluation Detailed Views: I/Q
.
Software Version
To check your R&S
CMW software version, open the "Setup" dialog and click "HW/SW
Equipment". The initial software version for each remote control command is quoted in
the reference description.
