SOURCE_2450

Set the source output settings. Use the OUTPUT_2450 block to turn the output on or off. Requires a CONNECT_2450 block to create the connection. Params: connection : VisaConnection The VISA address (requires the CONNECTION_2450 block). function : select, default=voltage The type of output to use. level : float, default=0 The fixed voltage or current to output. limit : float, default=1 Output limit (if function=voltage, current is limited and visa versa). terminal : select, default=front The panel to output from. protect : select, default=NONE The overvoltage protection value. Returns: out : String Source settings

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.
