Created attachment 537 [details] File showing triggered PulseView with no package that should have caused a trigger. Pre-Trigger Percentage is set to 20, but still trigger is at 0 Steps to reproduce: DSLogic Plus is connected to Computer running Pulseview. Setup DSLogic with 4 or less channels (to allow high sample rates support) Set Sample Rate to 200Mhz or 400Mhz Enable Rising Edge trigger on a channel with non-continous data (Like some sparse SPI packets) Click "Run" The DSLogic will trigger right away, even if no package is detected. Also the pre-trigger percentage will be ignored and the trigger will be at 0.
