In this example, a Keithley 2450 to generate 1V and then sweep between 0 and 1V.

First the necessary blocks were added:

• CONNECT_2450
• BEEP_2450
• RESET_2450
• SOURCE_2450
• MEASURE_SETTINGS_2450
• MEASUREMENT_READ_2450
• IV_SWEEP_2450
• BIG_NUMBER
• LINE

The instrument address was set for each 2450 block. The SOURCE_2450 block was changed in order to source 1V. The parameters in the MEASURE_SETTINGS_2450 block were changed as necessary. The MEASUREMENT_READ_2450 block was connected to the BIG_NUMBER block in order to view the reading.

The IV_SWEEP_2450 block output was connected to the LINE plot to show the output of the sweep.

The blocks were connected as shown and the app was run.
