On the marker output page, you can set the behavior and parameters of the Marker signal that is
provided at the front panel MARKER OUT BNC connector.
Marker Mode:
• Automatic: the marker has a behavior that depends on the Run Mode. In detail:
o Continuous: the instrument generates a Marker pulse of the duration of 8 sampling
clock periods, synchronous with the analog outputs, for each sequencer entry and for
each repetition.
o Single/Burst: each time a trigger event has been received, while the instrument is
waiting for a trigger event, a Marker pulse is generated of the duration of 8 sampling
clock periods.
o Triggered Continuous: at the start event the instrument generates a Marker pulse of
the duration of 8 sampling clock periods.
o Stepped: each time a trigger event is received, while the instrument is waiting for a
trigger event, a Marker pulse is generated of the duration of 8 sampling clock periods. In
case an entry with infinite repetitions is being executed, if a trigger event occurs, a
Marker pulse will be generated and the execution will skip to the next entry. In this case
the Marker pulse could be not synchronous with the waveform of next entry.
o Advanced: each time a trigger event has been received, while the instrument is waiting
for a trigger event, a Marker pulse is generated of the duration of 8 sampling clock
periods. The marker pulse is generated also each time a Jump event occurs; in this case
