Agilent Technologies E1441A user service DELete

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.
