Test Signal Injection Option:
• Allows a closed loop RF check of the TTA system.
• Requires a second RF cable to be installed at site.
• Test signal is injected into this second cable at the PDU,
Test signal enters TTA RX path via a 30 dB coupler in
TMA enclosure.
• A test signal injection off/on switch on PDU controls a relay
in the TTA which allows the RX antenna to be disconnected
if desired from the system during test, or test can be conducted
with antenna to avoid disruption to system.
• Level of test signal can be measured at RX multicoupler output port.
• Top amp can be manually bypassed at PDU to measure closed loop
signal level with and without top amp in line to verify operation.
• Order TTA unit with “-R” for Test Port
• For DBSMCP PDU order with Alarm option that includes test port
(see DBSMCP Datasheet)
• “Test Port Injection Kit” For DBCNRX PDU order DBCN1NJKT separately
