Time interval arrows are shown between its rising and falling edges.

Its 0-level indicator has a darker color.

You can recognize the currently selected Active wave as follows: Use (shift+)Tab to Activate the (previous)next wave. In order to select another wave as Active wave, simply tap/click that wave.

This is only shown for the currently selected Active wave (see below) and for the wave underneath the mouse pointer. The Logic Analyzer contains a feature which indicates the time between various rising or falling edges. To re-activate a hidden wave, simply tap its indicator residing at the bottom-right corner. The wave will be hidden, and its indicator will be moved to the bottom-right corner. To hide a digital wave, tap its indicator as shown below, and select hide. When you hide a digital wave, the remaining signals will be enlarged. This is especially useful in Mixed mode, where the graph area can be small.

You can also hide inactive digital waves, which will free up graph space for other signals. When you release the wave, all waves will auto-snap to their optimal position. Repositioning is pretty straightforward: simply drag any digital wave or its indicator to wherever you desire. In some cases where you don’t need 8 digital inputs, you might want to reposition or even hide some of them as they can clutter the screen. The grid is split in 10 horizontal divisions, and the timespan of each division is displayed in the Timebase indicators, on the bottom-right of the screen. The grid can help you determine the timebase of your signal as well.

The image below shows how timebase zooming on can be done: By pinching you can continuously zoom in or out to an arbitrary value. Zooming by mouse or keyboard will switch between predefined values. This can be achieved using the following operations: Dragging the indicator has the benefit that it auto-snaps to the grid divisions.ĭragging will also occur when, while pinching, you move both fingers in the same direction.ĭepending on whether you want to visualize a fast signal or a slow signal, you’ll want to set the timebase accordingly. Using touch/mouse, you can drag your waves or the horizontal trigger indicator. You’ll also want to position your waves to your liking. These actions are described below in more detail. Change the timescale so the key part of the communication is fitting inside the graph.Move the trigger position (pan) so the start of the communication is shown on the graph.Since you’re probably using the LA for visualizing digital communication, you’ll want to Some elements are the topic of other articles:įirst you’ll want to make sure you have optimal visibility on your digital wave. This image can be used as reference for the rest of this text. The key parts of the Logic Analyzer screen are shown on the image below.
