Short Display Lagging in Roll Mode (TBS2074B, 70MHz)

Hi Max,

This delay is caused by the fact that the TBS2kB isn't displaying the whole record length on the screen (you can see this at the top of the screen), which means about 0.5 to 1 s of record is off the screen to the right, which creates the delay you're seeing.
To reduce the delay I'd suggest decreasing the time/div.

Thanks for the reply, Afonso. Assuming I'll need at least 1s/div, would there be any way to force the scope display the whole record length? 

Hi Max,

It's possible to change the position with the horizontal position knob, but I did not see a significant improvement, which kind of disproves my theory.

I talked with our product line team but we were unable to come up with a workaround. For now, that's just the way it is, there's a bit of delay when capturing in roll mode.
