Roll Mode
The option for Roll mode operates on time base setting of 50 ms/div or
slower. This roll mode causes the waveform to move slowly across the
screen from right to left. If Roll mode is selected, there is no triggering
capability and the scope is acquiring data continuosly in auto trigger
mode. The Roll mode is useful in low frequency waveform to yield a
display in much like a strip chart recorder that allows the waveform to
roll across the display.
To enable trigger mode at 50 ms/div or slower time bases, go to User >
Acquire > Roll,Trig and select Trigger option to opt for triggering mode
instead of Roll mode. This enables triggering at these slower time bases.
NOTE
• The Zoom function is only applicable in Run Mode and NOT in Stop Mode.
• If Main function is selected during Zoom mode, the display will return to its previous
view before magnification.
NOTE
The spanning functions are not available for time base setting of 50 ms/div or slower and
125 ns/div or faster.
