[:SEGMent]:MARKer
[SOURce:]LIST[1][:SEGMent]:MARKer <marker_list> defines, for each voltage
point of a waveform segment, whether the Agilent E1445A may output a marker pulse.
To actually output a marker pulse, the marker enable list value for the segment
sequence entry for the segment must also be set to 1.
[SOURce:]MARKer:FEED must
be set to “
SOURce:LIST” to output the marker pulse on the “Marker Out” BNC;
[SOURce:]MARKer:ECLTrg<n>:FEED must be set to “ SOURce:LIST” to output the
marker pulse on the corresponding VXIbus ECLTRG* line.
Parameters The <marker_list> may be either a comma-separated list of values or an IEEE-488.2
definite or indefinite length block containing the values in 16-bit integer format. A
value of 0 generates no marker pulse; any non-zero value enables marker pulse
generation.
MINimum and MAXimum cannot be used with this command.
Comments • If block format is used, the most significant byte of each value must be sent first.
• Marker pulses are one sample period wide (nominally 25 nS at 40 MHz clock
rate). To widen the pulses, enable marker pulse generation on consecutive points.
• Usually, marker pulse generation is enabled on no more than one point of a waveform
segment. The
[SOURce:]LIST[1][:SEGMent]:MARKer:SPOint command is the most
efficient way to enable marker pulse generation on a single point.
• The waveform segment’s marker pulse list length must be the same length as its
voltage point list or must have a length of 1. If not, executing the
INITiate:IMMediate
command generates Error +1104,"Segment lists of different lengths".
• A marker pulse list of length 1 is treated as though it were the same length as the
voltage point list, with all marker pulse values the same as the specified value.
• The marker pulse list length must be no longer than the reserved length specified by
[SOURce:]LIST[1][:SEGMent]:DEFine. If the marker pulse list length is less than the
reserved length, only the number of points specified by the most recent marker pulse
and voltage point lists is generated when the waveform segment is output.
• Changing marker pulse values preserves the waveform segment’s voltage point
list, and vice versa.
• Executable when Initiated: No
• Coupling Group: None
