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. Note that the full Analog Graph functionality is also available in ‘’Mixed mode’’įile:SelectLA.png Logic Analyzer main screen Simply open up the main menu, and select ‘’Digital mode’’ to bring up the Logic Analyzer Graph. See the Connectors pinout article to find out which pins are reserved for the Logic Analyzer. Spikes/Transients outside this range are OK, as we have hi-speed bidirectional TVS diodes on each input.Applying voltages beyond this range can permanently damage the input channel!.3.3V, 5.0V: Up to 50MHz digital signals.4.1 Changing the trigger position (panning).1 Logic Analyzer - Hardware specifications.
