Marker mode pattern
Periodic marker where each period is defined by a bit pattern with a maximum length
of 64 bits. A "1" ("0") in the pattern denotes an On (Off) signal segment with a duration
of one sample/symbol period.
Example:
In the following example, the marker signal is defined by a pattern
100100...
.
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 several symbols/sample periods.
Example:
In the following example, the marker signal is defined by an "On Time" = 1 and "Off
Time" = 2.
Delaying marker signals
on page 93, 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
SMM100A 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.
