4 - Programming Examples

Clipped Waveform

To select a clipped sine waveform use:

FUNCtion:SHAPe CSINusoid

To set the clipping level to 50%, use:

FUNCtion:SHAPe:CSINusoid 50

The clipping level is the percentage of the peak amplitude at which clipping occurs.

The clipping level can also be specified in terms of the percent total harmonic distortion in the clipped sine waveform by adding a THD suffix to the command. For example,

FUNCtion:SHAPe:CSINusoid 10 THD

sets the clipping level so that the clipped sine has 10% distortion.

User-Defined Waveform

To create a user-defined waveform, use TRACe:DEFine command to create a name for the waveform, then use the TRACe[:DATA] command to send the list of 1024 amplitude points. The waveform can then be selected using the FUNCtion command. For example, a waveform named "Distortion" can be created with:

TRACe:DEFine DISTORTION

TRACe:DATA DISTORTION, n1, n2, n3, ..., n1024

where n1 ... n1024 are the data points that define the relative amplitudes of exactly one cycle of the waveform. The first data point defines the amplitude that will be output at 0 degrees phase reference.

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. Waveform data is stored in nonvolatile memory and is retained when input power is removed. Up to 12 user defined waveforms may be created and stored.

NOTE: Because waveform shape commands are coupled with the voltage commands, changing waveforms without changing the programmed voltage may result in an error if the resulting peak voltage amplitude exceeds the maximum voltage rating of the ac source. Refer to "Coupled Commands" for more information.
