c) P/t Multislot
As shown in Fig. 4-6 below, the P/t Multislot measurement results are similar to the P/t Normal GMSK
results. The following differences occur:
•
The first parameter line shows the selected Trig. Slot Offset , see p. 4.18 .
•
The info boxes, the diagram and the limit lines differ from the single-slot configuration, see below.

Info boxes
The info boxes show the following properties of the individual timeslots:
Power Average burst power in dBm. The Power result depends on the
display mode as indicated in the upper right corner of the
diagram.
Timing Timing error of the burst in symbol periods (actual timing minus
the slot offset times the nominal slot duration). The actual timing
of the burst is given by the training sequence and measured
relative to the measured timeslot
(Trigger Slot Offset 0; see Fig.
4-3 on page 4.18 ).
Below the two measurement results, an error message is displayed if the burst is
out of tolerance. An info box is provided for each timeslot displayed (1 to 4; see
Slot
Count hotkey on p. 4.57 ). The boxes can be suppressed altogether by means of
the Display/Marker – Info Box hotkey.
Remote control
Settings are retrieved using the query corresponding to the setting command
(setting command with appended question mark).
