RF Connections
Important
The PA may be damaged if the load is removed or switched
while the PA is transmitting.
The RF input to the TB9100 is via the lower BNC/TNC connector on the
rear panel of the reciter. The RF output is via the N-type connector on the
rear panel of the PA (refer to
Figure 4.8 on page 52 ).
We recommend that you use dual-screened coaxial cable such as RG223 for
the BNC/TNC connections, and RG214 for the N-type connections.
External Reference
For K4 Band, the internal frequency reference accuracy is inadequate, and
an external reference (eg. Tait T801-02)
must be used. The external
reference frequency can be 10MHz or 12.8MHz, with an input level of
300mV pp to 5V pp. The stability of this reference should be better than 50
parts per billion.
If an external reference is required, the CSS must be programmed to select
10MHz or 12.8MHz (“Configure > Base Station > Miscellaneous”), and
the external reference “Enable” and “Invalid” alarms can be enabled
(“Configure > Alarms > Control”).
