Created attachment 351 [details] square-wave Using a dslogic plus on the latest version of pulseview. I am unable to retrieve a clean trace of data. I created a simple square wave to recreate the problem. Attached is a trace of data from the dslogic plus using sigrok, a saleae using sigrok and a dslogic plus using dsview.
Created attachment 352 [details] square wave from saleae
Created attachment 353 [details] square wave from dsview
