I recently got a new Saleae Logic 8 and I’m super pleased with it. The only slight disappointment was there was no way to replicate the repeated “Normal” trigger mode that you get on all oscilloscopes. I find this mode very useful for a range of situations, and judging from existing forum posts and feature requests I’m not the only one. The “Trigger View” mode comes very close to what I’m looking for, but I often want to just be able to repeatedly trigger on an edge rather than a protocol word.
I’ve found a relatively nice workaround that allows you to do edge based repeated triggering and made a video about it here:
It works by setting up the “Simple Parallel” Analyzer on the channel you want to use as the edge trigger. You set both the D0 and Clock signal of the parallel bus to be that same channel. You then select either rising or falling edge for the clock depending on what edge to want to trigger on. For rising edge set the query to 1, and for falling edge set the query to 0. You can use the holdoff setting to prevent re-triggering to early just like with a normal oscilloscope. It is also possible to set up a trigger on an edge change, but gated by other channels being in specific logic states.
Note that the workaround only works on digital channels.
Hope this helps some people get the most from their analyzer
