InfiniiVision DSO-X 2022A trigger line disappears

Question asked by shirakaba on Sep 12, 2013
Hello

I have an InfiniiVision DSO-X 2022A running firmware 02.35.2013061800 and I wonder if I have hit a bug or a feature.

Running the trigger in DC Coupling mode (Mode/Coupling, Coupling DC) the T with the little marker is shown to the left and whenever the trigger level is changed, a trigger line appears for a while and the trigger level voltage is also shown in a little box in the upper right corner of the display.

If the trigger coupling is changed to AC or LF Reject, the little T with the marker disappears and the line never shows up, but the level in the top right corner still changes accordingly. Is this a firmware bug or just me not understanding the basics of these trigger settings?



Regards,
Nicklas
