TX/RX Antenna Connections
Starter (Stand–alone) Frames
Refer to NO TAG or NO TAG 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 NO TAG and NO TAG.
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 (NO TAG) or duplexed with TX signals through the single
DRDC ANTENNAS connectors (NO TAG).
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:
S 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.
