3. Enable the Supplies

This section walks through using the Discovery Power Supply (DPS3340) for the first time. We will use the +5V power supply to power an external device.

Power Supply Setup

1.

If you haven't yet, plug the Discovery Power Supply into an outlet, then plug the power supply into the Discovery Power Supply DPS3340.

2.

Plug the Discovery Power Supply into the computer via the USB cable.

3.

Flip the power switch on the left side of the Discovery Power Supply to the On Position and wait for the Discovery Power Supply DPS3340 to turn on.

4.

Plug in a set of banana plug connectors into the Output 1 port on the front of the Discovery Power Supply. Please connect the red banana plug to the red connector on the Discovery Power Supply DPS3340 and the black banana plug to the black connector. While theoretically you could use any color, keeping things the same will avoid confusion when working with your circuit. Use the alligator clip or minigrabber clips to connect the power supply to your Device Under Test.

5.

Launch the WaveForms application. Upon launch, WaveForms will automatically detect and connect to the Discovery Power Supply in the Device Manager. If the Discovery Power Supply is not connected to the host computer when WaveForms launches, plug in the device and turn it on, at which point it will appear in the Device Manager’s device list.

If your device doesn't show up, you can click the Refresh Stopped button to have WaveForms begin automatically refreshing the list of devices.

6.

In WaveForms, open the Supplies instrument by clicking on the Supplies button in the instrument panel on the left side of the screen. Set the voltage and current from the dropdown menu. Turn *off* the +15V and -15V power supplies, since we only are hooking up the 5V supply. Click Master Enable to turn the Power Supply on.
