- | === 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** drop-down allows for selection of trigger sources from other instruments. /* For more information, | ||
- | |||
- | The **Wait** drop-down allows for configuration of a delay after pressing Run (or the trigger event occurs). The value can be selected from the menu 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. | ||
- | |||
- | The **Run** drop-down 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 // | ||
- | |||
- | The **Repeat** drop-down 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 " | ||

- | **Output** switches between four output behaviors: | ||
- | |||
- | * //PP (Push-Pull):// | ||
- | * //OD (Open Drain):// possible output values are 0 and Z. Bus values are computed by treating Z as 1. Requires a pull-up resistor | ||
- | * //OS (Open Source):// possible output values are Z and 1. Bus values are computed by treating Z as 0. Requires a pull-down resistor | ||
- | * //TS (Tri-State):// | ||
- | |||
- | **Idle** determines if the line is set the //initial// value, //0//, //1//, or //Z// when no signal is being driven through | ||
- | |||
- | **Type** determines the output types. Since the **Parameter** columns depend on **Type**, they will be described alongside the signal type: | ||
- | |||
- | (NOTE: Not all parameters are used for all signal types.) | ||
- | * // | ||
- | * //Clock:// generates a clock signal. The frequency is set by **Parameter1**, | ||
- | * //Pulse:// generates a pulse signal. **Parameter1** determines if the signal is active high or low, the number of data points to hold the signal low is set by **Parameter2**, | ||
- | * //Random:// generates a random pattern of outputs at a frequency determined by **Parameter1**. | ||
- | * //Custom:// generates a custom pattern with frequency determined by **Parameter1**. The contents of the custom signal can be loaded from a file or set by hand by clicking the Parameter Editor button (see below) | ||

- | Each signal can be further modified by clicking the Parameter Editor button ({{learn: | ||

- | The **Show** drop-down will determine how much time per division to display. | ||

- | The **From** drop-down will determine what the start point will be on the plot. | ||
