Can someone help me identify some behavior of my scope? I'm new to scopes, but was playing with my DS1054Z last night. Data plotting only occurs after the graph gets past the "0" y-axis. Let's say i set the time-scale to 10-seconds per segment. There are 6-segments to the left of the 0-Y line, and 6-segments to the right. With this time scale, I must wait 60-seconds before I see anything graphed. Once it passes the 0-Y, line everything on the left 6-segments instantly shows up, and the next 6-segments plot in realtime. Once the graphing gets to +60-Y, I must wait another 60-seconds before the graph is updated.
If I set the scale to 1-second per segment, I must wait 6 seconds before I see anything, then I get real-time data plotting for the next 6 seconds.
If I move the horizontal marker to the edge of the furthest-left segment, I get plotting in realtime across all 12-segments. I figured this was some setting I accidentally enabled somewhere, but I can't find such a feature.
Does anyone have any ideas? Is this just the way that this oscope works?
