82 Agilent E1441A SCPI Command Reference
Chapter 3
CARDIAC. If you specify one of the built-in waveforms, a +782, “Cannot
overwrite a built-in arb waveform” error is generated.
• If you copy to a waveform name that already exists, the previous waveform is
overwritten (no error is generated). The five built-in waveforms are protected;
you cannot overwrite any of them.
• Up to four user-defined waveforms can be stored in non-volatile memory. If
memory is full and you try to copy a new waveform to non-volatile memory, a
+781, “Not enough memory” error is generated. Use the DATA:DEL
command to delete the waveform in
VOLATILE memory or any of the four
user-defined waveforms in non-volatile memory. Use the DATA:CAT?
command to list all waveforms currently stored in volatile and non-volatile
memory.
Example The following statement uses the DATA:COPY command to copy the waveform
currently in volatile memory to non-volatile memory with file name ARB_1:
"DATA:COPY ARB_1, VOLATILE"
"DATA:COPY ARB_1"(optional "VOLATILE" parameter omitted)
:DELete
DATA:DELete <arb name> deletes the specified arbitrary waveform from memory.
You can delete the waveform in volatile memory or any of the four user-defined
waveforms in non-volatile memory.
Parameters • The arb name may contain up to 8 characters. The first character must be a
letter (A-Z), but the remaining characters can be numbers (0-9) or the
underscore character (“ _ ”). Blank spaces are not allowed. If you specify a
name with more than 8 characters, a +783, “Arb waveform name too long”
error is generated.
• The function generator does not distinguish between upper- and lower-case
letters for the arbitrary waveform name. Therefore, ARB_1 and arb_1 are the
same name. All characters are converted to upper case.
Comments • You cannot delete the arbitrary waveform that is currently being output. If you
attempt to delete the waveform being output, a +787, “Cannot delete an active
arb waveform” error is generated.
• You cannot delete any of the five built-in arbitrary waveforms. If you attempt
to delete one of the built-in waveforms, a +786, “Cannot delete a built-in arb
waveform” error is generated.
• Use the DATA:DEL:ALL command to delete the waveform in VOLATILE
memory and all user-defined non-volatile waveforms all at once.
If one of the waveforms is currently being output, a +787, “Cannot delete an
active arb waveform” error is generated. The active waveform is not deleted
but all of the other waveforms are deleted.
