DATA Subsystem
DATA Subsystem
The DATA subsystem manages user-defined arbitrary waveforms:
l DATA:ARBitrary2:FORMat - specifies the order for bytes in a dual arbitrary waveform file (requires optional IQ
player).
l DATA:ARBitrary[1|2] - downloads arbitrary waveform voltages to waveform memory
l DATA:ARBitrary[1|2]:DAC - downloads arbitrary waveform DAC codes to waveform memory
l DATA:ATTRibute:AVERage? - returns arithmetic average of all data points for an arbitrary waveform or sequence
l DATA:ATTRibute:CFACtor? - returns crest factor of all data points in an arbitrary waveform or sequence
l DATA:ATTRibute:POINts? - returns number of data points for arbitrary waveform or sequence
l DATA:ATTRibute:PTPeak? - returns peak-to-peak value of all data points in an arbitrary waveform or sequence
l DATA:SEQuence - combines previously loaded arbitrary waveforms into a sequence
l DATA:VOLatile:CATalog - returns the contents of volatile waveform memory, including arbitrary waveforms and
sequences
l DATA:VOLatile:CLEar - clears volatile waveform memory
l DATA:VOLatile:FREE? - returns number of points available (free) in volatile memory
Examples
The following example uses DATA commands to set up an arbitrary waveform sequence. Note that the long
DATA:SEQuence command splits across lines for readability purposes.
Names of the form a## and ar##, such as a09 and ar27, refer to arbitrary waveforms.
