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

Front panel operations to output high-current pulses
You can use the Pulse Settings screen to configure the Model 2461 for pulsing from the front panel of
the instrument. It is important to set the digitize range to a level that will fit the pulse limit magnitude
before you make changes to the Pulse Settings screen. In this example, the instrument is configured
to source current and measure voltage. The source range is set to auto and the measure range is set
to 20 V.
To access the pulse settings screen:
1. Press the MENU key.
2. Under Source, select Pulse.
You can set all of the pulse specific settings used in this example on this menu screen, including the
type of pulse (Pulse Train, Linear Sweep with Steps, Linear Sweep with Points, or Logarithmic
Sweep). This example uses the Pulse Train option to generate the pulse.
Enter all of the parameters from Define the pulse train test parameters into the option fields. The
pulse setup is not saved until the Generate button is pressed. The Generate button notifies the
instrument to save all of the source, digitize, and pulse settings in configuration lists and the trigger
model.
To create and run the pulse configuration lists and trigger models:
1. Select Pulse Train from the list of pulse types.
2. Enter all pulse parameters into the applicable boxes.
3. Press Generate at the top of the screen to save the configuration.
4. Press the Trigger button to execute the pulses.
