Basic Operation

Roll - Horizontal Mode

Roll mode causes the waveform to move slowly across the

screen from right to left.

Note: It only operates on time base settings of 500

ms/div or slower. If the current time base setting

is faster than the 500 ms/div limit, it will be set to

500 ms/div when Roll mode is selected.

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 pause the display after a full screen of

acquisition in Roll mode, press the SINGLE key. To clear the

display and restart another full screen acquisition in Roll

mode, press the SINGLE key again.

Press the horizontal MENU key and then press the Roll

softkey to select the Roll mode. The waveform will move

slowly across the screen from right to left.

The fastest time base is 500 ms in roll mode.
