memory) will be returned. “Volatile” will be returned when a built-in waveform is
currently downloaded to volatile memory. To remove a waveform from volatile
memory or any use-defined waveforms in non-volatile memory, use DATA:DEL
command.
DATA:NVOLatile:CATalog?
List the names of all user-defined arbitrary waveforms downloaded to
non-volatile memory. Up to four waveform names will be returned. If there is no
waveform currently downloaded, a null string “” will be returned. To remove any
use-defined waveforms in non-volatile memory, use DATA:DEL command.
DATA:NVOLatile:FREE?
Query the number of available slots for storing the user-defined waveforms.
DATA:DELete
Remove the specific arbitrary waveform from memory. It can be the waveforms
in volatile memory or the user-defined waveforms in non-volatile memory. You
cannot delete an arbitrary waveform that is currently output, or an error will be
generated.
DATA:DELete:ALL
Remove all user-defined waveforms from memory. All waveforms in volatile
memory and user-defined waveforms in non-volatile memory will be deleted,
but the built-in waveforms in non-volatile memory will not be deleted. You
cannot delete an arbitrary waveform that is currently output, or an error will be
generated.
DATA:ATTRibute:AVERage? []
Query the arithmetic average of all data points for the specified waveform
(-1≤≤) . The default waveform is the currently active one (FUNC:USER
command). If you query a waveform which is not stored in memory, an error
“Specified arb waveform does not exist” will be generated.
DATA:ATTRibute:CFACtor? []
Query the crest factor of all data points for the specified waveform. The crest
factor represents the ratio of the peak value to the RMS value of the waveform.
The default waveform is the currently active one (FUNC:USER command). If you
