Trigger Source for Multi Evaluation Measurements
In the 1xEV-DO "Multi Evaluation" measurement use an "1xEV-DO Super Frame" trig-
ger source to obtain valid transmit time error results.
2.2.3 End to End Packet Data Connections
The R&S CMW with the data application unit provides an end to end packet data con-
nection between the core IP network and the access terminal.
2.2.3.1 Data Application Unit (DAU)
To set up a WCDMA packet data connection you need the Data Application Unit (DAU)
in addition to the "1xEV-DO signaling" application. The DAU itself is available as option
R&S CMW-B450x and the DAU measurements as R&S CMW-KM050. For IPv4 option
R&S CMW-KA100 is required, for IPv6 additionally option R&S CMW-KA150.
For configuration of the DAU, e.g. for initial configuration of the DAU IP settings, please
refer to the DAU's user manual.
When the packet data connection has been established, you can use the DAU to per-
form IP-based data tests (see DAU documentation).
You can also perform "RX Meas Data", see chapter 2.4.12.5, "Data View (Tab)" ,
on page 117.
Or you can perform other measurements that do not require a DAU, e.g. TX measure-
ments or "PER" or "Throughput" RX measurements
chapter 2.4.12, "RX Measure-
ment" , on page 106.
Most measurements require the transmission of data. For a test mode connection the
signaling application takes care of forward link data transmission. For a packet data
connection the signaling application does not transfer data. So you must generate IP
traffic by other means, e.g. using the DAU. You may for example initiate an IPerf mea-
surement or an FTP data transfer. For details refer to the DAU documentation. Some
DAU measurements and applications require to enter the IP address(es) assigned to
the AT. You can retrieve this information from the AT info section, see
"AT IPv4
Address, IPv6 Prefix" on page 57.
Please refer to the DAU user manual:
●
for configuration of the DAU, e.g. for initial configuration of the DAU IP settings;
●
for limitations, if more signaling instances use end to end connections in parallel.
2.2.3.2 Packet Applications
The packet applications are part of the 1xEV-DO application layer and are used for
transporting user data between the access terminal and the access network, see
chap-
ter 2.4.8.1, "Application Layer" , on page 80 .
