The security settings in the "Network" section of the configuration dialog must be in
accordance with the AT capabilities.
Order of steps
The measurements of the "1xEV-DO Signaling" application may be initiated before
turning on the forward signal. The measurement starts as soon as the preconditions
are fulfilled. An RX measurement for instance starts as soon as the connection has
been established.
If the measurement does not start
If the measurement does not start at all while the signaling application generates a
downlink signal, verify that the combined signal path scenario is selected in the mea-
surement.
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 2.3.12.5, "Data View (Tab)"
Or you can perform other measurements that do not require a DAU, e.g. TX measure-
ments or "PER" or "Throughput" RX measurements
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
