Section 10: Capturing high-power pulse waveforms Model 2461 Interactive SourceMeter® Instrument User's Manual

Viewing the source and digitize waveforms simultaneously on the
front panel
In this example, you enable source readback to capture the current source waveform and the voltage
digitize waveform. You can plot the two waveforms together on the same graph to examine time
dependencies between the two waveforms. This technique is very powerful and enables you to get a
detailed look at the pulse response of your DUT.
To plot the source waveform stored in defbuffer1:
1. In the graph screen, select the Data tab at the top of the screen.
2. Select Add Trace on the right side of the screen.
3. Select defbuffer1 from the list of reading buffers.
4. Select Source in the list of Buffer Elements.
5. Select the Graph tab at the top of the screen to return to the graph.
See the Model 2461 Reference Manual for more information on graphing operations. Both the source
trace and the digitize trace are displayed on the graph. Pinching and zooming on the touch screen
manipulates the Y-axis of the active trace and the X-axis of both traces. To switch between active
traces, press the trace button on the lower left of the screen.
