 +===== Introduction =====
 +This guide explains the use of the Discovery Power Supply with other Digilent equipment, like the [[test-and-measurement:analog-discovery-pro-5250:start|Analog Discovery Pro ADP5250]] inside of //Waveforms//.  The Analog Discovery Pro ADP5250 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, launch //Waveforms//.  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 ADP5250 and the Discovery Power Supply listed. Highlight the Analog Discovery Pro ADP5250 first and click on the //Select +// button on the dialog box.

 +//Waveforms// launches with the screen you are used to seeing.  But you will noticed there is a new icon in the list.  There is a //Supplies// Instrument, but that controls the power supply on the Analog Discovery Pro ADP5250.  The Discovery Power Supply can be controlled by clicking on the Discovery Supplies icon.

 +=== Taking Measurements ===

 +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 the [[test-and-measurement:analog-discovery-studio:canvases:breadboard-canvas:start|Breadboard Canvas for Analog Discovery Studio.]]

 +You'll notice in //Waveforms// that there is a //Supplies// instrument and a //Discovery Supplies// instrument.  Be careful as you are working with your setup.  When you are in the //Supplies// instrument you are controlling the triple out supply on the Analog Discovery Pro ADP5250 in this setup.  When you are in the //Discovery Supplies// instrument you are controlling the triple output supply on the Discovery Power Supply.

 +You can control things like the //Waveforms// Wavegen and scope instruments on the Analog Discovery Pro ADP5250.  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.
