使用一个发现电源other Digilent Equipment

This guide explains the use of the Discovery Power Supply with other Digilent equipment, like theAnalog Discovery Pro (ADP3450)inside ofWaveForms. The Analog Discovery Pro (ADP3450) has a Power Supplies instrument already, but by adding the Discovery Power Supply you get three additional supplies and a 5V supply with higher current output. Adding a Discovery Power Supply to your setup expands your capabilities as you are designing circuits.

Launching WaveForms

With both devices hooked up to your PC via the included USB cables and turned on, launchWaveForms. At the Device Manager screen, you will see the list of Demo devices and the two devices that are plugged in. In this case, you see both the Analog Discovery Pro (ADP3450) and the Discovery Power Supply listed. Highlight the Analog Discovery Pro (ADP3450) first and click on theSelect +button on the dialog box.

Now you can select the additional device to add toWaveForms.

WaveFormslaunches with the screen you are used to seeing. But you will noticed there is a new icon in the list. There is aSuppliesInstrument, but that controls the power supply on the Analog Discovery Pro (ADP3450). The Discovery Power Supply can be controlled by clicking on theDiscovery Suppliesicon.

Working with Multiple Devices

The first step is building up a test circuit. Here we have a bunch of LEDs, a bar graph, a load resistor, and a capacitor we can charge with the press of a button, all on theBreadboard Canvas for Analog Discovery Studio.

You'll notice inWaveFormsthat there is aSuppliesinstrument and aDiscovery Suppliesinstrument. Be careful as you are working with your setup. When you are in theSuppliesinstrument you are controlling the triple out supply on the Analog Discovery Pro (ADP3450) in this setup. When you are in theDiscovery Suppliesinstrument you are controlling the triple output supply on the Discovery Power Supply.

You can control things like theWaveFormsWavegen and scope instruments on the Analog Discovery Pro (ADP3450). On another note, make sure you make the power supply grounds common in your circuit. You will notice errors in scope measurements if the grounds are not common.
