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 from 6ns to 12 ns
(depending on the sampling frequency), 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 from 6ns to 12
ns (depending at the sampling frequency).
o
Triggered Continuous:
at the start event the instrument generates a Marker pulse of
the duration from 6ns to 12 ns (depending at the sampling frequency).
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 from 6ns to 12 ns (depending
at the sampling frequency). In case an entry with infinite repetitions is being executed, if
a trigger event occurs, a Marker pulse will be generate and the execution will skip to the
next entry. In this case the Marker pulse is not synchronous with the waveform of next
entry
•
Fixed To Low Voltage/ Fixed To High Voltage:
the marker level is fixed to low level or high level.
•
Replicate Digital 0:
it means that The Marker Out will behave like the Digital line 0 output. This
choice is available only when the digital option is installed and the
Digital Channels
parameter
(Channel Settings -> DIG page) is > 0.
Marker Skew[s]:
defines the skew between the marker and the analog channels. The resolution is 78 ps.
The edited value is automatically rounded to the closest value that the hardware can implement.
Voltage Level[V]:
it sets the Marker high level Voltage. The Low level is fixed to 0V.
Sequencer Settings
The sequencer setting page contains some parameter to define the strategy to manage the length of the
sequencer entries in relationship with the length of the channel waveforms defined for each entry.
