-=== 1.1 === +
-Plug in your <test & measurement device>, then start WaveForms and make sure your device is connected. +
- +
-If no device is connected to the host computer when WaveForms launches, the **Device Manager** will launch automatically.  +
- +
-Make sure that the device is plugged in and turned on, at which point it will appear in the Device Manager's device list (1). Click on the device in the list (“DEMO” devices are also listed, which allow the user to use WaveForms and create projects without a physical device) to select it, then click the **Select** button (2) to close the Device Manager. +
- +
-**Note:** //The Device Manager can be reopened by clicking on the “Connected Device” button in the bottom right corner of the screen (3), or by selecting “Device Manager” from the “Settings” menu at the top of the screen.// +

-//This section walks through setting up the //Pattern Generator// to generate a signal on a single channel.// +
-<WRAP group> +
-<WRAP column half> +
-=== 2.1 Software Setup === +
-On the left panel, select the "Click to Add channels" (1 in image at right) or the green plus button ({{:learn:instrumentation:tutorials:analog-discovery-studio-logic-analyzer:symbol_plus.png?nolink}}). The menu that pops up allows signals to be added as individual lines, a bus, a standard protocol, or a custom protocol. To add individual lines, select "Signal" (2) and use CTRL and/or SHIFT to select multiple lines. For now, select DIO 0 and click "Ok". Under the **Type** column, choose "Clock" from the dropdown menu and leave the other settings in their default state.  +
- +
-Return to WaveForms' Welcome page by clicking on its tab at the top left of the screen and select //Logic//. Alternatively, press the green plus button next to "Welcome" in the tab to add the instrument (3). On the left panel, select the "Click to Add channels" button or the green plus button ({{:learn:instrumentation:tutorials:analog-discovery-studio-logic-analyzer:symbol_plus.png?nolink}}). From "Signals" select DIO 0 and click "Ok". For a detailed tutorial on using the //Logic Analyzer// instrument, click here (FIXME). +

-=== 2.2 Generate Data === +
-In the //Pattern Generator// instrument, click the Run button ({{:learn:instrumentation:tutorials:waveforms-buttons:waveforms-run.png?nolink}}) button in the control bar, and then click the Run button in the //Logic Analyzer// instrument (1 & 2, respectively, in the image to the right). The signal being generated by the //Patterns// instruments should appear in the //Logic Analyzer// instrument. +

-==== 3. Pattern Generator User Interface Overview ==== +
-//This section walks through the wide variety of controls and features available in the //Pattern Generator// instrument// +
-<WRAP group> +
-<WRAP column half> +
-=== 3.1 Control Interface === +
-The bar near the top contains several options for controlling the pattern generator.  +
- +
-The //Run/Stop// button starts and stops the pattern generator. +
- +
-The //Trigger// dropdown allows for selection of trigger sources from other instruments. For more information, please see the **Cross-Triggering Guide** FIXME link. +
- +
-//Wait// allows for configuration of a delay after pressing Run (or the trigger event occurs). The value can be selected from the dropdown or typed in. If typing, be sure to enter a unit (ns, us, s, ms, ks, Ms) to avoid defaulting to the wrong order of magnitude. +
- +
-//Run// determines the period of time the pattern generator will generate a pattern for. It also automatically changes the horizontal time axis in the plot (unless manually overridden as shown in section 3.2), making it so the //Pattern Generator// plot always shows a single period of the pattern (if "continuous" is selected) or the the entire pattern that will be generated (if a time period is selected).  +
- +
-//Repeat// is available if the //Pattern Generator// is set to run for a finite amount of time, and will cause the instrument to generate the pattern the set number of times. In "continuous" mode this option is greyed out and set to "infinite". +

-=== 3.2 Pattern Signal Controls === +
-Starting from the left, the plus ({{learn:instrumentation:tutorials:analog-discovery-studio-pattern-generator:minus.png}}) and minus ({[learn:instrumentation:tutorials:analog-discovery-studio-pattern-generator:minus.png?nolink}} buttons can be used to add or remove channels. +
- +
-The //Show// icon ({{learn:instrumentation:tutorials:analog-discovery-studio-pattern-generator:show.png?nolink}}) selects which parameters are shown for each channel. The first four parameters (//Output//, //Idle//, //Type//, and //Parameter1//) are available for every type of signal, while the last 2 parameters are type-specific. The selections available in different parameters will change depending on the signal type. +
- +
-//Output// changes between four output behaviors: **PP-Push-Pull**, **OD - Open Drain**, **OS - Open Source**, **TS - Tri-State**. +
-  +
-  * PP: possible output values are 0 and 1. +
-  * OD: possible output values are 0 and Z. Bus values are computed by treating Z as 1. Requires a pull-up resistor +
-  * OS: possible output values are Z and 1. Bus values are computed by treating Z as 0. Requires a pull-down resistor  +
-  * TS: possible output values are 0, 1, and Z. Bus values containing Z will be displayed as a question mark. +

-=== 3.3 Plot Controls === +
-If the plot needs to be set to show a specific point in the pattern, this can be achieved using the dropdown menus directly below the control bar. The menu with "Auto" it it by default needs to be set to "Manual" to change the other two menus. +
- +
-//Show// dropdown will determine how much time per division to display. +
- +
-//From// will determine what the start point will be on the plot. +
