Component
Function
GPIB Connection
The GPIB connection between both test sets and a controlling PC are necessary if
remote control of the instruments in the system is required.
Ethernet Switch or
Hub
An Ethernet switch or hub is required to connect the following:
• UE to external servers
• PC running WPA (Wireless Protocol Advisor) to the 8960
•
PC running N6061A Protocol Logging and Analysis software
Only one 8960 and one PXT can be connected at any time.
Refer to the 8960-WCDMA Documentation
or (GSM/GPRS/EGPRS Documentation) for further setup
required on the Agilent 8960.
Setting the Software Parameters
The connection between the 8960 and PXT can be initiated from the 8960 or via the EPC interface within
the PXT.
Initiating Connection From:

Performing Cell Reselections
You must have already completed the two setup procedures above:
• Connecting the Hardware Components
• Setting the Software Parameters
and set all other 8960 parameters as appropriate for the DUT.
Cell Reselections from UTRAN/GERAN to LTE
With a UE camped on the legacy 3GPP network, it is possible to reselect to the PXT acting as the LTE cell.
For a typical network, the WCDMA cell will normally broadcast SIB19 LTE
neighbor information (refer to WCDMA SIB19 Setup
). Even though the UE may
require this, it is not essential from an operational perspective.
Likewise the SI-2quater information is transmitted to broadcast the LTE neighbors
on GERAN.
The PXT (LTE Cell) must be running a scenario (on the appropriate LTE frequency band and EARFCN) that
handles the TAU (Tracking Area Update) messaging.
