Appendix F. BER Test Procedure
The Bit Error Rate (BER) Diagnostic Test is used to execute BER tests of the MC-Series
system. The Diagnostic Test supports multi-channel RadioBlade (MCRB) transceivers in
both the 900 MHz band and the 800 MHz bands and also two-port, 800-band
RadioBlade
®
(RBD2) transceivers. BER testing gives a pass/fail determination for each
blade and should be performed on all blades in the RadioBlade shelf (RBS).
The most common testing scenario involves acceptance-test plan (ATP) execution during
incoming inspection and commissioning. The MC-Series system can be taken out of
service for testing during a maintenance window. The RadioBlade transceivers can be
locked as a group and then unlocked one-by-one for the BER tests.
F.1 Prerequisites for Testing
These procedures presume that the MC-Series system is in place at its site of service
and operational. Therefore, the prerequisites for operation will already have been
satisfied:
• The T1 is live and has been tested.
• The datafill has been completed, including BR cabinet and position
assignments, and conforms to the recommended datafill.
• All site cabling and installation work has been completed and all punchlist items
corrected.
• The system is powered and operational.
• The software is at least Revision 14.x.xxx.
In addition, the following conditions are required for BER testing:
• The BER test requires that the RadioBlade Shelf be connected to an ISC.
• The RadioBlade transceiver under test must be in the active state and
unlocked (UEA).
F.2 Test Tool
• Signal generator (sig gen)
A Motorola R2660 Communications Analyzer can be used as the source of the test
signal for the MC-Series system during the BER test.
F.3 Testing Strategy
In the MC-Series system as in the Motorola Enhanced Base Transceiver Station (EBTS),
BRs are identified by cabinet and position, with frequencies assigned in the datafill. BRs
in the MC-Series are logical instances that map to physical RadioBlade transceivers.
RBD2 and the MCRB transceivers can be mixed in a system (on a single RBS), and both
the RBD2 and the MCRB can operate in a Quad BR configuration. Like the EBTS, the
MC-Series system can be organized as a single sector (Omni), or as two or three sector
site.
The basic BER testing strategy is to record the Base Radio (BR) and corresponding
RadioBlade configuration of the MC-Series system, and then test each blade across the
power spectrum in its assigned range(s) of frequency.
