RBS3202 Test with CMU300 and RNC/Iub SIM

1CM56_E 5 Rohde & Schwarz

4 Test Setup

Please create the test setup according to the following block diagrams.

Transmitter measurements:

The input RF 1 to the R&S CMU300 is directly connected to the transmitter

output. Continuous power of 47 dBm RMS (54 dBm PEP) is possible on

this input. Externally applied attenuator pads can be considered in the R&S

CMU300 when configuring the RF paths. We strongly recommend that you

deactivate any DC excitation voltages that may be hooked up to RF lines.

Note: If the BTS uses remote amplifiers (tower-mounted), these must be

taken into consideration in the test setup, that is, the R&S CMU300 must

be directly connected to the RF connectors on the amplifier.
