(CABLE-RFS)”. Ensure that the information is recorded under the channel number that
is on the cable label.
Step 24. Repeat steps 5 through 8 for the remaining seven antenna cable inputs on the RFS.
Step 25. Change the frequency to the next test frequency (refer to Test Setup). Perform steps 1
through 9 until the RFS has been successfully tested at the frequencies given in Table
K4.
Procedures – TTA Base Station
Equipment Required
• Signal Generator - Agilent 8648D, or suitable alternative, tunable to the RFS center
frequency
• Spectrum Analyzer - Agilent E4404B, or equivalent
• QMA female to SMA Female adapter
• Three N-type male test cables.
• Two Female/Female N-type barrel connectors.
• RFS test box for RFS tests only (not required for cable tests) – see Figure K13
Figure K13: RFS & RFC Test Box
• JP1 - Cable port to be connected to the RFC or the RFS.
• M1/M2 - RFC DC output test points.
• Load Button - Tests RFC full Current load. Used in
conjunction with Power LED by JP1.
• RX/TX switch - Supplies power to the RX or RX circuit
in the RFS.
• RFC/RFS switch - Moved to the RFS for testing of the
RFS and to the RFC for testing of the RFC.
• 10.7MHz - Test point to measure the 10.7 MHz signal
output of the RFC.
• J1 - External control of switches. (Engineering use only)
• P1 - DC power supply connection. (Used for RFS testing
only)
• JP2 - Connection point for test equipment (DC blocked
port)
Equipment Set-up
• Spectrum Analyzer - connected to the test cable / QMA adapter on BTS end
