6.0 PERFORMANCE TESTING
6
This series of tests characterizes the receive performance of the Base Station in terms of
its absolute sensitivity and its sensitivity relative to the local noise floor at the installed
site.
The base station is capable of providing a raw discriminated output to support analog
receive testing. The output is provided on the "Q" Transmitter output of the BSC when
the base station is in output mode 0.
Required Test Equipment:
• PC running suitable console application
• Cisco “Black” cable
• Cisco RJ-45 to DB9 (F) adapter
• Or, 9-Pin Male to 9-Pin Female w/null adaptor
• HP 8920 Communications Analyzer
• 30dB Directional Coupler
• Parallel Printer & Cable
6.1 ANALOG RECEIVE TESTS (MANDATORY)
6.1.1 12dB SINAD Receiver Sensitivity
Objective: The 12dB SINAD test measures the effective receive sensitivity and signal to
noise ratio of the RF Channel. This test is performed at the RF input
connection, on the
BSX.
Compare the results with the staging area data.
STEPS ACTION MISCELLANEOUS
1.
Connect the PC to the Terminal port of
the DCX of the base station under test.
Note:
Requires Black Cisco cable &
adapter and a communications data
rate of 19,200 bps.
2.
Ensure that the Disable/Enable
switches on all HPA’s are
DISABLED.
