TRACe
DATA
These commands set the values of a user-defined waveform table.
The first parameter is the name of a waveform that was previously defined with
TRACe:DEFine. Following the name are 1024 data points that define the relative
amplitudes of exactly one cycle of the waveform. The first data point defines the
relative amplitude that will be output at 0 degrees phase reference. An error will
occur if exactly 1024 data points are not sent with the command.
Data points can be in any arbitrary units. The ac source scales the data to an
internal format that removes the DC component and ensures that the correct AC
rms voltage is output when the waveform is selected. When queried, trace data is
returned as normalized values in the range of 1. You can query the predefined
SINusoid, SQUare, or CSINusoid waveform shapes, but you cannot use the
predefined names as names for your waveform.
Waveform data is stored in non-volatile memory and is retained when input power
is removed. Up to 12 user-defined waveforms may be created and stored. The
*RST and *RCL commands have no effect on user-defined waveforms.
A waveform can be selected for output using the FUNCtion:SHAPe,
FUNCtion:SHAPe:TRIGgered, or LIST:SHAPe commands.
