Info
Box
The hotkey Info Box switches the info boxes for all displayed timeslots on or off.
For a description of the info boxes see section P/t Multislot on p. 4.23 ff.
Remote control
No command, display configuration only
Timing
Offset
The Timing Offset hotkey shifts the burst by the entered number of symbol periods,
e.g. to compensate for a known, constant timing error of the MS. See section
Measurement Control (Power Configuration – Control) on p. 4.28 ff.

Modulation
View
The hotkey Modulation View defines the expected modulation scheme in all four
timeslots that can be measured and adjusts the power/time template. To obtain a
valid measurement result, the actual modulation in all measured slots (see
Fig. 4-3
on p. 4.18 ) must be compatible with the Modulation View settings. See section
Measurement Control (Power Configuration – Control) on p. 4.28 ff.

Level
Scale
The Level Scale hotkey defines a maximum RF level in dBm (Max) and a level
range in dB (Span) that will be displayed in the graphical diagram and thus
determines the scale of the y axis.
Remote control
No command, display configuration only
Time
Scale
The Time Scale hotkey defines the start time (Start) and the total time interval
(Span) that will be displayed in the graphical diagram and thus determines the
scale of the x axis.
Both values are expressed in symbol periods. 1 symbol corresponds to approx.
3.69
µ
s so that 1 timeslot comprises 156 ¼ symbols. Start is expressed relative to
symbol 0 of the measured timeslot (see Fig. 4-3 on p. 4.18 ). Time Scale only
configures the diagram; it does not affect the number of timeslots actually
measured but is modified as this number is changed (see
Slot Count hotkey on
p. 4.57 ).
Remote control
No command, display configuration only
Default
Scale
The Default Scale hotkey sets a default Level Scale and a default Time Scale , the
latter corresponding to the number of timeslots measured (see Slot Count hotkey
on p. 4.57 ) plus an appropriate display margin.
