Remote control
No command, screen configuration only.
Rel
The Rel. 2 hotkey switches the delta marker 2 on or off (use the ON/OFF key).
Functions and remote control are analogous to delta marker 1.
D-Line
The D-Line hotkey switches the D-line in the test diagram on or off.
The D-line is a horizontal, colored auxiliary line in the test diagram and is used for
marking a level value and for measuring level differences. The level (ordinate) is
determined in the input field
D-Line and indicated on the D-line. The permissible
value range is the diagram area, the default setting is Off.
The switch D-Line Config. is opened by pressing D-Line twice and determines
whether the D-line level is expressed in absolute units (in dBm, setting absolute) or
relative to the Max. Level (in dB, setting relative).
Remote control
No command, screen configuration only.
Display
Marker
The Display/Marker softkey zooms or shifts the graphical display. It is selected by
pressing the Marker/Display softkey twice. If pressed once again, the selected
Display/Marker softkey changes back to the Marker/Display softkey, see above.
Display
Area
The Display Area hotkey selects the displayed screen area.
It is possible to select either the complete burst (see Fig. 4-11 ), or zoom in to a
particular area:
Full Range Display of complete burst in the time range –10 symbols
to 157 symbols and levels between –80 dBc and 10 dBc
Useful Part Full time range, measurement curve magnified around the
reference level
Left Upper Corner Measurement curve magnified around the left upper
corner
Rising Edge Full level range, time axis from –10 symbols to 10
symbols
Right Upper Corner Measurement curve magnified around the right upper
corner
Falling Edge Full level range, time axis from 139 symbols to 157
symbols
The screen setting and the measurement do not affect each other.
Remote control
No command, screen configuration only.
Timing
Offset
The Timing Offset hotkey shifts the burst by the entered number of symbols.
The burst is shifted relative to the time axis and the tolerance template for the burst
analysis, see section
Limit lines (Power Configuration – Limit Lines) on page 4.32 .
Therefore, the value of Timing Bit Offset affects the result of the tolerance check.
