Example Defining a Waveform Segment Voltage Point List
LIST:SEL ABC Selects waveform segment ABC.
LIST:DEF 8 ABC is 8 points long.
LIST:VOLT .5,1,.5,0,-.5,-1,-.5,0 Defines waveform voltages.
[:SEGMent]:VOLTage:DAC
[SOURce:]LIST[1][:SEGMent]:VOLTage:DAC <voltage_list> defines the series of
output voltage points that constitute a waveform segment. The points are specified
in terms of digital-to-analog converter (DAC) codes.
Parameters The <voltage_list> may be either a comma-separated list of DAC codes or an
IEEE-488.2 definite or indefinite length block containing the DAC codes in 16-bit
integer format.
The DAC code is a 16-bit two’s complement or unsigned number (see the
[SOURce:]ARBitrary:DAC:FORMat command). With
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] 5.11875 V set and a matched
output load, the least significant bit (LSB) represents 1.25 mV. The legal range for
the DAC codes is -4096 through +4095 for signed numbers, 0 through +8191 for
unsigned numbers.
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.
• The voltage point list length must be at least four points long but no longer than
the reserved length specified by
[SOURce:]LIST[1][:SEGMent]:DEFine. If the
voltage point list length is less than the reserved length, only the number of points
specified by the most recent voltage point and marker pulse list is generated when
the waveform segment is output.
• 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".
• Changing marker pulse values preserves the waveform segment’s voltage point
list, and vice versa.
