Three marker output signals are available; they can be output at the User x connectors
or at the T/M 1/2 connectors.

Marker modes
Marker mode restart
The generated marker signal is a single "On" pulse. The rising edge of this pulse is
generated at the signal generation start and at each subsequent signal restart time.
This marker can be used to monitor the effects of the selected trigger, e.g. trigger caus-
ing restarts of the signal generation.
Marker mode pulse
Periodic marker with consecutive On and Off periods of equal length. The first On
period starts at the beginning of the first generated sample/symbol. The marker fre-
quency is defined by a "Divider". The frequency is derived as follows:
<Frequency> = "Symbol/Sample Rate" / "Divider", respectively
<Frequency> = "Sampling Frequency" / "Divider".
Example:
"Symbol Rate = 1 Msym/s", "Divider = 2"
The marker frequency is 500 kHz, corresponding to a marker period of 2 us. Each On
and Off period has a length of 1 us, corresponding to one symbol period. With a divider
of 4 (6, 8 ...), the length of each On and Off period is increased to 2 (3, 4, ...) symbol
periods.
