The BCCH Information test can be tailored to provide only certain information from the
BCCH decode (the default is to show all information). To do this, select the BCCH
Information tab as shown in Figure 65.

Control Description
Apply a BCCH Information
Type
If ticked, the settings of the other controls will be used.
If not ticked, all of the other controls will be treated as
though they were ticked.
RXLEV If ticked, the measured RXLEV will be reported.
RXQUAL If ticked, the measured RXQUAL will be reported.
Freq Error & Quality If ticked, the measured Frequency Error and
Frequency Quality will be reported. The Frequency
Error is a signed value measured in ppb. It is the
amount by which the nanoBTS’s timebase frequency
exceeds the monitored channel’s BTS timebase
frequency. The Frequency Quality value is a
monotonically increasing measure of quality of the
estimate of frequency error derived by the BTS. The
value zero is the lowest quality.
Frame Offset If ticked, the measured Frame Offset will be reported.
The Frame Offset is measured in units of quarter bits,
and is an unsigned 16 bit integer, which shall not
exceed 4999 (5000 being a complete frame offset). It
is the amount by which the nanoBTS’s frame timing is
in advance of the monitored channel’s frame timing.
