4.5.3 Working with Control and Marker List Editor
The control and marker signals for digital modulation and digital standards can be very
conveniently graphically defined in a "Control and Marker List Editor". The available
marker signals – and, with custom digital modulation, the CW, Hop, Burst Gate and
Lev Att control signals – can be defined in this editor.
While it is being processed, the file is continuously automatically buffered. Depending
on the size of the file, saving may take some time.
The various functions of the editor are explained in the individual menus. This section
focuses to the general use of the graphic editor.
Example:
The following figure shows the "Slot Marker Definition Editor" of the "GSM/EDGE" dia-
log as an example.
The upper area displays the signal for which the marker signals are to be defined. On
the left side, the available signals (marker and control signals) are listed and colour-
coded.
Auxiliary functions are offered in the lower editor area, e.g. presetting for the ramps in
the marker signal, cursor positioning by entering the bit position and possible editing by
means of value entries in a table.
The actual graphic definition of the control signals occurs in the center area of the edi-
tor. Each control signal is represented by means of a colored line along the bit axis. A
cursor can be shifted alongside this line and marks the position where a ramp is to be
set. The color of the cursor changes depending on the current function.
Use the ENTER key to switch over between the colors (and therefore functions):
●
black: marks the bit position on the marker line
●
yellow: sets a ramp
●
green: activates the marked ramp for shifting.
