Agilent E1441A SCPI Command Reference 83
Chapter 3
: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”.
