10 Arbitrary Waveform Commands
104 U2761A Programmer’s Reference
DATA:DAC VOLATILE
Syntax
DATA:DAC VOLATILE, {<binary block>|<value>, <value>, . . . }
This command downloads the arbitrary data in binary block or decimal
integer values from –8191 to +8191 into volatile memory. You can
download from 1 point (a DC signal) to 65536 (64K) points per waveform
in IEEE- 488.2 binary block format or as a list of values. The range of
values corresponds to the values available using internal 14- bit
Digital- to- Analog Converter (DAC) codes. The U2761A takes the specified
number of points and expands them to fill up the waveform memory.
Parameter
Remarks
• The values of –8191 and +8191 correspond to the peak values of the
waveform (if the offset is 0 V).
• The maximum amplitude will be limited if the data points do not span
the full range of values between ±8191.
• The DATA:DAC command overwrites the previous waveform in volatile
memory (and no error will be generated).
