The top line of the display indicates the log entry number, and the time and date
of the entry. Note that in accordance with international convention, the date is
shown in DAY-MONTH-YEAR format.
The bottom line of the display shows the statistics data which has been measured
and recorded.
The meaning and format of the numbers is as follows:
Minimum Eb/No, Average Eb/No, Maximum TPLI, Average TPLI
(where TPLI means Transmit Power Level increase, if AUPC is enabled).
The user defines a measurement interval (see MONITOR, STATS,
CONFIGURE) and during this interval, Eb/No and TPLI are observed, at a one
second rate. At the end of this period, the average Eb/No is calculated and
recorded, and the minimum value seen in the interval. Similarly, the average
TPLI is calculated, along with the highest value seen in the interval.
