b) P/t Normal 8PSK
As shown in
Fig. 4-47
below, the
P/t Normal 8PSK
measurement results are similar to the
P/t Normal
GMSK
results. The x-axis scale of both diagrams is equal because 8PSK and GMSK symbol periods
are of equal length. The following differences occur:
•
The default limit lines differ from the GMSK limit lines.

c) P/t Multislot
As shown in
Fig. 4-48
below, the
P/t Multislot
measurement results are analogous to the corresponding
Non Signalling
mode results; see section Measurement Results on page
4.20
ff. The following
differences occur:
•
The first parameter line indicates the PCL of the mobile phone under test instead of the
Frequency
Offset
of the RF input signal.
•
The actual TDMA timeslot
(Meas. Slot)
replaces the
Trig. Slot Offset;
