Use the Configure Source Type dialog to configure the fundamental settings of your simulated source waveform. Once your waveform is defined, click Output Enable button to turn on the waveform. The button is green when the waveform is enabled. To view the waveform on the oscilloscope, click the channel button in the Configure Simulation Source dialog. Select Invert Signal to invert the waveform.

Open this dialog from the Configure Simulation Source dialog.

Always perform an Auto Scale after configuring the source waveform.

Source Waveform Type

Use the Waveform Type field to select a Data, Clock, Function, or Load from File. The Format can be selected from NRZ or PAM4. For Function waveforms, you can select from the functions: Sine, Cosine, Square, Triangle, and Sawtooth.

For Data waveforms, use the Format field to select the type of simulated data format: NRZ or PAM4. Select the Pattern from one that is shown in the following table. If you select Load from File, you can click Browse to select a pattern waveform file. Both .wfmx and .csv formats are supported. This feature allows you to work offline with your data. It is recommended that you also save a FlexDCA setup file when you save your original waveform. When you load the waveform file, also load the setup file to ensure that the FlexDCA settings match those of your waveform file

Use the Waveform Data Rate field to enter the waveform's symbol rate or click Select From List to choose a standard symbol rate.

Waveform Amplitude and Offset

Use the Amplitude and Offset fields to enter the simulated waveform's amplitude and offset in volts for electrical waveforms and Watts for optical waveforms.

PAM4 Level Adjustment

Use the Level 1 and Level 2 fields to create a PAM4 waveform that has non-linearity. You can perform a Linearity measurement on this waveform in Oscilloscope mode, Eye mode, and Jitter mode. By default, level 1 is set to 33.3% and level 2 is set to 66.7%.

The ability to adjust the amplitude of PAM4 levels requires the Research and Development Package License.
