Record the data in the RFS System Test Form under “TOTAL RX PATH LOSS (CABLE-
RFS)”. Ensure that the information is recorded under the channel number that is on the cable
label.
Repeat steps 5 through 8 for the remaining seven antenna cable inputs on the RFS.
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 O4.
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
?? SMA male to N-type male test cable (Note: The cable can be changed but additional
adapters will be required.)
?? RFS test box for RFS tests only (not required for cable tests) – see Figure O13
Figure O13: 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)
