Marker mode ON/OFF ratio
Similar to "Pulse" but with independent lengths of the On and Off periods. The length of
the periods is entered as a number of symbols/sample periods.
Example:
In the following example, the marker signal is defined by an "On Time" = 1 and "Off
Time" = 2.
Marker mode CList
This is not one of the most common modes.
The instrument generates a marker signal that is defined in the selected control list.
The R&S
SMBV100B provides a graphical interface for convenient definition of control
signals among others also for the marker signals.
Delaying Marker Signals
on page 94, the marker starts at the
beginning of the first generated sample/symbol (sample/symbol no. 1). It is possible
though to delay the start of the marker by an integer number of symbols/sample peri-
ods.

Baseband Trigger Signals
The R&S
SMBV100B provides several trigger modes, different trigger sources, and
some additional trigger settings to suppress or delay the trigger events. This section
provides an overview of the provided baseband trigger settings and the impact of the
trigger settings on the signal generation.
The current signal generation status ("Running" or "Stopped") is continuously dis-
played in the corresponding dialog, indicated in the header of the tab and in the block
diagram of the instrument. This indication is important when an external trigger is
applied.
For information on the trigger signals used in the RF domain, see
nal Generation and Triggering in the Sweep and List Modes"
Trigger
The trigger signals are internally generated or externally supplied signals which start
signal generation at a particular point in time. However, signal generation can also take
place without triggering. In this case, the signal generation stars immediately after the
modulation is enabled.
