Section 1 TRACER Description

9Preliminary

Three SMA connectors, located on the RFC module, provide RF and IF connection points. A test point is

provided for monitoring the received signal strength indicator (RSSI). The voltage (relative to the GND

test point) present on this test point represents the level of the received signal. This signal is used to align

the antenna when installing the system and to verify the link is performing as designed. Another test

point is provided to monitor the transmitter output power during system configuration. The only

connections that must be made in the field are a coax connection between the baseband processor and the

RFC and a coax connection between the RFC and the antenna. These connections require male, type N

coax connectors.

The IF connector provides the connection between the baseband processor and the rackmounted or

mastmounted RFC. (An 8-inch IF cable [ADTRAN part # 3125RF027@A] is provided for rackmount

systems). The TO ANTENNA connection provides the connection between the RFC and the antenna. A

block diagram of the RFC functions is show in Figure 1-9.

The RFC module is enclosed in either a 19-inch EIA rackmount housing, or a weather-tight enclosure

suitable for mastmounting near the antenna for enhanced system performance. The RFC mastmount and

rackmount housings are illustrated in Figures 1-10 and 1-11.
