Product Description
Optional Equipment
Optional test equipment and other optional items are described in the following sections.
GPS Time and Frequency Reference Receiver
The Test Software supports the Symmetricom 58503A GPS Time and Frequency
Reference Receiver for supplying the timebase signal normally taken from the Base
Station equipment.
When connecting to the Base Station SCT modules as the timing reference, the Test
Software uses the signals out of the modules as though those signals are correctly timed
to GPS time to provide the correct PN offset (see “Test Set to GPS Time and Frequency
Reference Receiver Connections” on page 50). If a problem exists in the Base Station
GPS reference or SCT modules, the Base Station PN offset will likely be incorrect.
Use of the 58503A provides a GPS-referenced timing signal that is independent of the
Base Station. This helps isolate problems associated with the Base Station own GPS
reference equipment and/or SCT module(s). An example of this is an “island cell”, where
the Base Station passes performance tests but does not properly interact with adjacent
cells during handoffs.
Accessory Kits
Several kits containing selections of accessories for connecting the Test Set to the Base
Station equipment are available from Agilent Technologies. These are described in the
following three sections.
Agilent Technologies E8300A 8935 Base Station Accessory Kit
The Agilent Technologies E8300A 8935 Base Station Accessory Kit (see Table 1-1)
supplies serial cables, RF cables, and adapters required to connect the Test Set for
testing Base Stations.
