d) P/Frame, P/Slot Graph, P/Slot Table
The results displayed in the measurement menu
Power
, applications
P/Frame, P/Slot Graph,
and
P/Slot Table
are analogous to the corresponding
Non Signalling
mode results; see section

ff. In
Signalling
mode, the PCL of the mobile phone under test is
indicated in the parameter line instead of the
Frequency Offset
of the RF input signal.
In
Signalling
mode, the burst timing and the numbering of the timeslots within a TDMA frame is known.
Therefore, the
P/Slot Graph
menu always shows a full TDMA frame (slot 0 to 7); the first timeslot
doesn't have to be determined with a trigger condition. In the
P/Slot Table
application, the first timeslot
displayed corresponds to the beginning (slot 0) of a TDMA frame. In the
P/Slot Frame
application, the
used timeslot in all consecutive TDMA frames is displayed.
e) P/PCL
The measurement menu
Power
, application
P/PCL,
contains a table of all measured average burst
powers.
Fig. 4-49 Display of measurement results (P/PCL menu)
PCL/Channel
The
PCL/Channel
table contains the average burst power for all PCLs supported by
the mobile, starting with the maximum output power (lowest PCL) and in the three
or seven channels selected via the
Channel
softkey. If the tolerance value defined
in the
Limits
card of the
Power Configuration
menu (see section
Limit Lines (Power
Configuration – Limit Lines)
on p. 4.112 ff) is violated, the result is shown on a red
background.
If more than 16 different PCLs are supported, the table contains a scrollbar.
