CDMA2000 Base Station Measurements (Option K82)
This section explains basic CDMA2000 base station tests by means of a setup with a signal generator,
e.g. an R&S SMU. It describes how operating and measurement errors can be avoided using correct
settings. The measurements are performed with an R&S FSL equipped with the CDMA2000 Base
Station Measurements option (K82).
The following measurements are described:
Measuring the Signal Channel Power
Measuring the Spectrum Emission Mask
Measuring the Relative Code Domain Power and the Frequency Error
– Synchronization of the reference frequencies
– Behavior with deviating center frequency setting
Measuring the triggered Relative Code Domain Power
– Adjusting the trigger offset
– Behaviour with the wrong PN offset
Measuring the Composite EVM
Measuring the Peak Code Domain Error and the RHO Factor
– Displaying RHO
Furthermore, the test setup for base station tests is given:
Test Setup for Base Station Tests
As the CDMA2000 Base Station Measurements option also supports the CDMA2000 Standard, the
examples are performed on an CDMA2000 signal.
General test setup:
The measurements are performed with the following units and accessories:
R&S FSL equipped with the CDMA2000 Base Station Measurements option
R&S SMU signal generator equipped with option SMU-B9 / B10 / B11 baseband generator and SMU-
K46 CDMA2000 incl. 1xEVDV.
1 coaxial cable, 50
, approximately 1 m, N connector
2 coaxial cables, 50
, approximately 1 m, BNC connector
This option is available from firmware version 1.90.
Measuring the Signal Channel Power
In the Power measurement, the total channel power of the CDMA2000 signal is displayed. The
measurement also displays spurious emeissions like harmonics or intermodulation products that occur
close to the carrier.
