PRELIMINARY

WARNING

1. All transmit connectors must be properly terminated for all

ATP tests.

2. Before the FER is run, be sure that one of the following is

done:

- All transmitter connectors are properly terminated

- All LPAs are turned OFF (circuit breakers pulled)

Failure to observe these warnings may result in bodily injury or

equipment damage.

TX/RX Antenna Connections

Starter (Stand-alone) Frames

Refer to Figure 1-7 or Figure 1-8 for identification of starter frame

transmit and receive antenna connections where measurements are to be

taken. All ATP test equipment connections for starter frames are made at

the ANTENNAS connectors on the RF interface panel.

Companion Frames

TX ATP Antenna Connections - Each companion frame at a site

connects independently to transmit antennas. Test equipment

connections for TX ATPs on each companion frame are made at the

ANTENNAS connectors as on starter frames. Companion frame

ANTENNAS connectors are shown in Figure 1-9 and Figure 1-10.

Antenna Connections for RX main ATP - Each companion frame at a

site uses independent receive antennas for main RX signals. The main

RX signals are either routed through TRDC RX ANTENNAS

connectors (Figure 1-10) or duplexed with TX signals through the single

DRDC ANTENNAS connectors (Figure 1-9).

Antenna Connections for RX diversity ATP - Companion frame

diversity RX signals are obtained from the RX main antenna of the

collocated companion frame. The main RX signals are sent from the

collocated companion frame through inter-frame diversity RX cables to

the RX EXPANSION 1B, 2B, or 3B connectors of the frame where they

are used for diversity RX (refer to Figure 4-1). Diversity RX ATP test

equipment connections are made at one of two different locations

depending on whether or not the companion frame under test is

connected to a collocated companion frame. Connection points for each

situation are as follows:

 Connected companion frames: When inter-frame diversity RX

cables are connected, connect test equipment for diversity RX ATP at

the ANTENNAS connectors of the collocated companion frame as

shown in Figure 4-1 and listed in Table 4-1. Be sure MPC is selected

before logging the LMF into the frame or FER will fail.
