[SOURce:]ROSCillator
The source outputs the reference oscillator selected by
[SOURce:]ROSCillator:SOURce.
TRIGger[:STARt|:SEQuence[1]]
The source outputs a nominal 12 nS marker pulse for each point of a
waveform segment.
Arbitrary Generated Marker Pulses
To generate marker pulses for arbitrary waveforms, do the following:
• Select the “[SOURce:]LIST[1]” source for the front panel “Marker
Out” BNC connector using
[SOURce:]MARKer:FEED
“[SOURce:]LIST[1]”.
• Select the marker pulse polarity using [SOURce:]MARKer:POLarity
<
polarity>.
• Enable the AFG to output a marker list using
[SOURce:]MARKer[:STATe] <mode>.
• Define a marker list in a waveform segment using
[SOURce:]LIST[1][:SEGMent]:MARKer <marker_list> or
[SOURce:]LIST[1][:SEGMent]:MARKer:SPOint <point>.
• Enable the waveform segment in a segment sequence to output the
marker list using
[SOURce:]LIST[1]:SSEQuence:MARKer
<
marker_list> or [SOURce:]LIST[1]:SSEQuence:MARKer:SPOint
<
point>.
Generating Marker
Pulses for Arbitrary
Waveforms
The following programs show how to generate the marker pulses using two
different methods. The two methods are:
1.
[SOURce:]LIST[1][:SEGMent]:MARKer defines for each point in a
waveform segment where a marker is to be output. Likewise,
[SOURce:]LIST[1]:SSEQuence:MARKer enables (or disables) marker
outputs for each waveform segment in a segment sequence.
2.
[SOURce:]LIST[1][:SEGMent]:MARKer:SPOint defines a single segment
or point in a waveform segment where the marker pulse is to be output.
Likewise,
[SOURce:]LIST[1]:SSEQuence:MARKer:SPOint enables a
marker output for a single waveform segment in a segment sequence.
