Power Steps...
These table rows provide a statistical evaluation of the measured power steps for
which the indicated step size has been expected.
In test step A a size of 0 dB is expected for all 60 power steps. In test step B (C) a size
of 0 dB is expected for 4 consecutive power steps and a size of +1 dB (-1 dB) for the
fifth power step. So there are 40 steps of 0 dB and 10 steps of
±
1 dB in step B and C.
The columns indicate the maximum, minimum and average measured power step
value. The column "Statistics" indicates how many power step values have been con-
sidered for the statistical evaluation.
Power Steps Group 0 dB A
This table row provides a statistical evaluation of the power step groups within test step
A. Each group comprises 10 adjacent power steps. The step sizes within a group are
summed up and result in a power step group value. Thus the total step sizes of power
step 1 to 10, 2 to 11, 3 to 12 etc. are calculated.
The columns indicate the maximum, minimum and average power step group value
determined in this way. The column "Statistics" indicates how many power step group
values have been considered for the statistical evaluation.
For the determined minimum and maximum value, the number of the first slot of the
group is indicated as "Beginning @ Slot".
Power Steps Group +/- 10 dB B/C
These rows consider all power steps within test step B or C. The sizes of all 50 power
steps of the test step are summed up and result in a power step group value. The
expected total step size 10 dB for step B: (4 x 0 dB + 1 x 1 dB) x 10. For step
C it equals -10 dB.
Thus there is only one power step group value for test step B and one value for test
step C. They are indicated in column "Maximum".

Inner Loop - Test Steps EFGH
This section describes the results in inner loop power control mode for the TPC test
step setups E, F, EF and GH.
The result view displays two diagrams and a table with statistical results.
