I just updated to the latest version of the software 126.96.36.199 Automotive, and it doesn't seem to matter what I do with the lowpass filtering - There is no effect in the display of the waveform. Occasionally, it will momentary look like it is switching on and then immediately back to unfiltered. And of course right after I update I need to look at a couple oxygen sensors on a car, which I need a printout for the customer. Very hard to show them what I'm talking about with all the noise. It was working before. Should I post a snapshot of what is going on?
I seem to remember reading something like this happening before to someone else. I just can't remember or find it again. Was it re-installing the device driver?
Appreciate any insight.
