Proceed as follows:
1. Set up a connection. The general procedure for connection setup is described in
the application sheet "LTE Combined Signal Path Measurements", see
ter 2.3.1.2, "Setting up a Connection"
For IP-based data tests, insert the following step after opening the configuration
dialog:
a) In section "Connection", set parameter "Connection Type" to "Data Applica-
tion".
This step enables the support of protocol stack layer 3 in the signaling applica-
tion.
2. In the main view of the signaling application, note the IPv4 address assigned to the
UE during attach. You need this information in the following sections.
Alternatively, if your UE is connected to a PC with Windows operating system,
open a command shell at the PC and type
IPconfig
to retrieve the IP address
information.
3. Open the "Data Application Measurements", e.g. from the task bar (press "TASKS"
to open the task bar).
If the application is not present in the task bar, enable it in the "Measurement Con-
troller" dialog (press "MEASURE" to open the dialog).
4. At the top of the GUI, select the LTE signaling application (parameter "Select
RAN").
The expected maximum throughput resulting from the current signaling settings is
displayed to the right for information.
2.3.2.3
Measuring the Latency with Ping
After completed test preparation, you may ping your UE and evaluate the reported
round-trip latency.
Proceed as follows:
1. Select the "Ping" tab.
2. For parameter "Destination IP" enter the IP address of the UE.
3. Press ON | OFF.
The measurement starts and the "Ping" softkey indicates the "RUN" state.
The graph shows the measured round-trip latency for each executed ping request.
