Remote Unit. The 305-xxxx system selects test tones at 2400, 2440 and 2483 MHz; the 306-xxxx

phase. As with the RF Calibration, System Check can be scheduled to reoccur in user-specified
maintenance windows or be performed on a one-off basis. The Full System check (includes antenna
cross coupling between multiple Remote Units) of a 64 Remote Unit system (i.e. maximum number of
Remote Units on a Primary Hub) should take approximately 15-20 minutes. It is recommended that the
Full System check is done during the original system commissioning. Select Omit antenna cross-
coupling if a more limited antenna scan with reduced run-time is required.
the TX-RX antenna isolation for an RU will be reported with '>=' (greater than or equals symbol)
Note:
pre-pended if the value measured was impaired by background noise/interference at the time of the
measurement. This occurs when the measurement with an active test tone is not at least 1dB above
the maximum background noise level recorded when the test tones were off. All we can be certain of
is that the TX-RX antenna isolation will not be lower than the value shown. It is also possible that the
TX antenna may be disconnected in this scenario.
When the symbol '-' is displayed in place of a TX-RX isolation number in the report, this represents an
unmeasurable TX-RX antenna isolation. The measured RX signal level was not sufficiently above the
RU RX noise floor. This could be due to either antenna being disconnected, or a very high TX-RX
antenna isolation condition, due to wide antenna separation or low antenna gain at the frequencies
used for the test.
It is important that the System Check is run when the building is as quiet as possible (e.g. 2am), to
minimize measurement errors due to background RF noise. The wide-band RU RX power
measurement cannot distinguish between wanted power for test (from RU Tx signal), and other uplink
background noise power received. Inconsistent antenna isolation or cross-coupling measurements
may occasionally be logged due to some background interference being present in that location at the
time of the test. Logging and comparing isolation measurements obtained over a number of System
Check runs should help highlight where to focus on-site attention.

Alarm Counts

This View lists all units/modules for which the count of any alarms is non-zero (the Alarm Count is a
cumulative number for all the instances of an alarm since the last system restart).
