I'm not sure if this is the right place to report what I think is a bug in waveforms.  I'm using version 3.16.3 64-bit on windows 10. I was having difficulty using averaging in the scope timebase controls to eliminate some noise.  When I click on 'single' acquisition, the scope appears to trigger the appropriate number of times (e.g., 100) before displaying a new trace. But the noise is not reduced, as if the scope is showing me just the trace from the first (or maybe the last) trigger.
