Measuring the Relative Code Domain Power
A code domain power measurement on one of the test models (model 1 with 32 channels) is shown in
the following. To demonstrate the effects, the basic parameters of the Code Domain Power
measurements permitting an analysis of the signal are changed one after the other from values adapted
to the measurement signal to non–adapted values.
Test setup:
Connect the RF output of the signal generator to the input of the R&S FSL.
Connect the reference input (EXT REF) on the rear panel of the R&S FSL to the reference input of
the signal generator (coaxial cable with BNC connectors).
Signal generator settings (e.g. R&S SMU):
Frequency: 2.1175 GHz
Level: 0 dBm
Standard: WCDMA/3GPP
Test model: 1, 32 DPCH channels
Procedure:
1. Set the R&S FSL to its default state.
Press the PRESET key.
The R&S FSL is set to its default state.
2. Change into the 3G FDD BTS mode.
Press the MODE key and activate the 3G FDD BTS option.
