Agilent Technologies E1441A user service Del:All, NVOLatile:CATalog?, NVOLatile:FREE?

:DEL:ALL

DATA:DELete:ALL deletes all user-defined arbitrary waveforms from memory. This command deletes the waveform in VOLATILE memory and all user-defined waveforms in non-volatile memory. The five built-in waveforms in non-volatile memory are not deleted.

Comments • The colon before the ALL parameter is required.

DATA:DELete:ALL

If you insert a space instead of a colon, the function generator will attempt to delete an arbitrary waveform with the name “ALL”. If no such waveform is stored in memory, a +785, “Specified arb waveform does not exist” error is generated.

•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 <arb name> command to delete stored waveforms one at a time.

:NVOLatile:CATalog?

DATA:NVOLatile:CATalog? lists the names of all user-defined arbitrary waveforms currently downloaded to non-volatile memory. Returns the names of up to four waveforms in non-volatile memory.

Comments • A series of quoted strings separated with commas is returned (see example below). If no user-defined waveforms are currently downloaded to non-volatile memory, the command returns a null string ( "" ).

"ARB_1","ARB_2","ARB_3","ARB_4"

•Use the DATA:DEL command to delete the waveform in VOLATILE memory or any of the user-defined waveforms in non-volatile memory.

:NVOLatile:FREE?

DATA:NVOLatile:FREE? queries the number of non-volatile memory slots available to store user-defined waveforms. Non-volatile waveform memory is divided into four 16k-point slots. The command returns the available memory slots to store user-defined waveforms: “0” (memory full), “1”, “2”, “3”, or “4”.
