DATA:CATalog?
List the names of all waveforms currently available for selection.
Returns the names of the five built-in waveforms (non-volatile memory),
“VOLATILE” if a waveform is currently downloaded to volatile memory,
and all user-defined waveforms downloaded to non-volatile memory.
• A series of quoted strings separated with commas is returned as
shown in the example below.
"VOLATILE","EXP_RISE","EXP_FALL","NEG_RAMP",
"SINC","CARDIAC","TEST1_ARB","TEST2_ARB"
•Use the
DATA:DEL
command to delete the waveform in volatile
memory or any of the user-defined waveforms in non-volatile memory.
DATA:NVOLatile:CATalog?
List the names of all user-defined arbitrary waveforms downloaded to
non-volatile memory. Returns the names of up to four waveforms.
• A series of quoted strings separated with commas is returned as
shown in the example below. If no user-defined waveforms are
currently downloaded, the command returns a null string ( " " ).
"TEST1_ARB","TEST2_ARB","TEST3_ARB","TEST4_ARB"
•Use the DATA:DEL command to delete any of the user-defined
waveforms in non-volatile memory.
DATA:NVOLatile:FREE?
Query the number of non-volatile memory slots available to store user-
