Roll Mode
Press the Acquire button to enter the acquire menu and press the Roll Mode
softkey to enable the roll mode.
In Roll mode the waveform moves slowly across the screen from right to left. It
only operates on time base settings of 50 ms/div or slower.
In Roll mode there is no trigger. The fixed reference point on the screen is the
right edge of the screen and refers to the current moment in time. Events that
have occurred are scrolled to the left of the reference point. Since there is no
trigger, no pre- trigger information is available.
If you would like to stop the display in Roll mode, press the
Run/Stop button. To
clear the display or restart an acquisition in Roll mode, press the Run/Stop button
again.
Use Roll mode on low- frequency waveforms to yield a display much like a strip
chart recorder. It allows the waveform to roll across the display.
