785 Specified arb waveform does not exist
The arb name specified with the FUNC:USER or DATA:DEL command
has not been downloaded into memory. Use the DATA:CAT? command to
list all waveforms currently downloaded. To download a waveform into
memory, use the DATA VOLATILE or DATA:DAC VOLATILE commands.
This error may also be generated if you insert a space instead of a colon
before the ALL parameter in the DATA:DEL:ALL command. The colon
before the
ALL parameter is required – otherwise, the function generator
will attempt to delete the arbitrary waveform with the name “
ALL”.
786 Cannot delete a built-in arb waveform
You cannot delete any of the five built-in arbitrary waveforms.
The following names are reserved and cannot be deleted with the
DATA:DEL command:
SINC, NEG_RAMP, EXP_RISE, EXP_FALL, and
CARDIAC.
787 Cannot delete the currently selected active arb waveform
You cannot delete the arbitrary waveform that is currently being
output. Either select a different arbitrary waveform or change to a
different output function.
788 Cannot copy to
VOLATILE arb waveform
The DATA:COPY command copies the arbitrary waveform from volatile
memory to the specified name in non-volatile memory. The source for
the copy operation is always “
VOLATILE” (you cannot copy from any
other name) and you cannot copy to
VOLATILE.
790 Arb waveform must contain at least 8 points
You cannot create an arbitrary waveform with fewer than 8 data points.
Redefine the waveform with between 8 and 16,000 data points.
800 Block length must be even
The function generator represents binary data as a 12-bit integers,
which is sent as two bytes (DATA:DAC VOLATILE command only).
An odd number of bytes is not accepted because the function generator
would not know how to interpret the last single byte.
810 State has not been stored
The memory location specified in the *RCL command was not used in a
previous *SAV command. You cannot recall the instrument state from a
memory location that was not previously specified as a storage location.
