TRACe:CATalog?
DATA:CATalog?
These queries return a list of defined waveform names. The list includes both pre-defined waveforms such
as SINusoid, SQUare, and CSINusoid, as well as any user-defined waveforms.

TRACe:DEFine
DATA:DEFine
These commands define a new waveform with the name <waveform_name> and allocates storage for its
data. The waveform name can then be referenced by the TRACe:DATA command to define its data
values.
An optional second argument is accepted for SCPI compatibility although it serves no useful purpose in
the ac source. The second argument can be the name of an existing waveform, or the number of points in
the trace. When a second name is sent, tha data from the first waveform name is copied to the second.
When the number of points in the trace is sent, only the number 1024 is accepted.
Command Syntax
TRACe:DEFine <waveform_name> [, <waveform_name> | 1024]
DATA:DEFine <waveform_name> [, <waveform_name> | 1024]
Parameters
<waveform_name>
Examples
TRAC:DEF flattop
