2.2.21 RLC Throughput Measurement
The WCDMA Signaling "RLC Throughput" measurement provides the total data
throughput (PDU) and the useful data throughput (SDU) in the downlink and in the
uplink.
RLC Throughput Dialogs
The R&S
CMW provides a separate tab and configuration dialog for RLC Throughput
tests, to be accessed from the "Measurement Controller" dialog, entry "RX Measure-
ment...".
2.2.21.1
Performing RLC Throughput Measurements
You can perform the measurement either with an end to end data connection or with
an RMC test mode connection.
The required steps are described below for both alternatives.
Measurement with end to end data connection
You must set up an end to end data connection and generate IP traffic. For these tasks
you need a Data Application Unit (DAU) and related options.
1. Set up an end to end data connection as described in
The required options are also listed there.
2. Use the DAU to generate IP traffic in the direction to be measured (uplink and/or
downlink). You may for example perform an IPerf measurement. Or you could
transfer data via FTP.
For details refer to the DAU documentation.
3. Start the "RLC Throughput" measurement and evaluate the results.
Measurement with RMC test mode connection
You must set up an RMC test mode connection with specific loop settings. A DAU is
not required.
1. Set up an RMC test mode connection with the following settings:
● parameter
= "Loop Mode 1 RLC"
● parameter
= "Acknowledge"
2. Start the "RLC Throughput" measurement and evaluate the results.
