-This guide walks through the process of setting up WaveForms' Scope instrument and capturing some data. The user interface of the instrument is briefly described. 
  
-FIXME This guide only pertains to the Analog Discovery 2 and Analog Discovery Studio. Other Digilent Test & Measurement devices have a different UI for their Supplies instrument.

-//This section walks through setting up the power supplies and voltmeter to measure the DC output of the power supplies// 
-<WRAP group> 
-<WRAP column half> 
-== 2.1 Hardware Setup == 
-In order to measure the output of the variable power supply pins, these pins must be connected to something that can measure voltages. While a standard digital multimeter or voltmeter could be used, this guide will show how to use WaveForms' //Voltmeter// instrument to measure the supply voltages. 
- 
-Connect the <test & measurement device>'s positive programmable supply output pin (red wire, labeled "V+") to the device's analog input channel 1 pin (orange wire, "1+"). 
- 
-Connect the <test & measurement device>'s negative programmable supply output pin (white wire, "V-") to the device's analog input channel 2 pin (blue wire, "2+"). 
- 
-If the <test & measurement device> has differential analog input channels, make sure to connect the analog input channel negative pins, labeled "1-" (orange wire with white stripes) and "2-" (blue wire with white stripes) to the device's ground (black wire, marked with a down arrow).

-== 2.2 Software Setup == 
-With the loopback circuit set up, WaveForms' //Voltmeter// instrument must be set up to report measured DC voltages. 
- 
-From the //Supplies// tab, opened in step 1.2, return to WaveForms' Welcome page by clicking on its tab at the top of the screen. In the Welcome tab, open the //Voltmeter// instrument, then click the "Run" button ({{:learn:instrumentation:tutorials:waveforms-buttons:waveforms-run.png?nolink}}) in the control bar near the top of the window to begin capturing data. The DC voltage measured on each analog input channel is reported in the "DC" row of the table just below the Run button. 
- 
-In order to show both the //Voltmeter// and the //Supplies// instruments on the screen at once, click on the "Docking Windows" button in the top right corner of the screen. (To return to the default tabbed view later, click on the "Tabbed Windows" button adjacent to the Docking Windows button)

-== 2.3 Enable the Supplies == 
-When the //Supplies// instrument is first opened, the power supplies are disabled (FIXME grounded or floating?). 
- 
-The "Master Enable" button can be used to switch the each of the programmable supplies off or on at once. The "Positive Supply" and "Negative Supply" buttons can be used to enable or disable each of the two programmable supplies individually. While the Master Enable is off, each power supply can be set to a Ready or Off state, if the supply is ready, it will be turned on when the Master Enable is set to on. 
- 
-Make sure that both power supplies are ready, then click on the Master Enable button to turn both of them on.

-== 2.4 Individual Supply Controls == 
- 
-In addition, each "Voltage" field can be used to set the voltage output by that supply. This field can be set by either typing a voltage value, including units, into the text field, or by using the dropdown to select a value. When a value is entered that is outside of the possible range for the <test & measurement device>, the value is clamped to the nearest voltage that can be output. \\ 
-FIXME Set the Voltage field for the Positive Supply to 1V, then watch the Voltmeter instrument as the change is reported. 
- 
-The output voltage level can also be changed by adjusting the slider to the right of the voltage field. \\ 
-FIXME Click and drag the slider for the Negative Supply, then watch the Voltmeter instrument as the changes are made in real time. 
- 
-The gear button (FIXME) to the left of the slider allows the user to narrow the range of voltages that can be used for both the slider and Voltage field for that channel. 
- 
-As previously mentioned in step 2.3 of this guide, each power supply has its own enable/disable button. \\ 
-FIXME Disable the Positive Supply, and watch as the Voltmeter's Channel 1 DC voltage field changes to near 0V.

-== 2.5 Controlling both Supplies == 
-As previously mentioned, each supply can be enabled or disabled at once using the Master Enable button. 
- 
-The "Tracking" checkbox, between the two channels, when checked, mirrors any changes made to the voltage output by one channel on the other channel. For example, if the positive supply is set to output 2V, the negative supply will automatically be changed to output -2V.

-== 2.6 Menu Bar == 
-The "File" menu, in the menu bar at the top of the supplies instrument, allows the user to save and load //Supplies// instrument configurations. 
- 
-The "Control" menu exposes the same functionality as the Master Enable Button, and lists hotkeys that can be used to quickly stop and run the power supplies. 
- 
-The Window menu provides a fast way to switch to other tabs open in WaveForms.
