TB9400 Installation and Operation Manual

© Tait Limited March 2015

The requirements for an external frequency reference and a 1PPS signal are 
set out in the following table. 

An NTP source is also strongly recommended for P25 Phase 1 systems. 
This will ensure log timestamps are synchronized, which will assist the 
diagnosis of faults.

It is beyond the scope of this manual to list every piece of equipment that 
an installation technician should carry. However, the following tools are 
specifically required for installing the base station:

■

Pozidriv PZ3 screwdriver for the M6 screws used in the DC input 
terminals on the PMU; M6 (0.25in) screws are also used to secure the 
subrack to the cabinet in factory-assembled systems

■

Pozidriv PZ2 screwdriver for the M4 screws used to secure the module 
retaining clamps, and for the fasteners used to secure the front panel to 
the subrack

■

8mm AF spanner for the SMA connectors, and the subrack ground 
connector.

You can also obtain the TBA0ST2 tool kit from your regional Tait office. 
It contains the basic tools needed to install, tune, and service the base 
station.
