Roll Mode
Press the
Roll
button to enter 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 and slower. If the current time base setting is
faster than the 50 ms/div limit, it will be set to 50 ms/div when Roll mode is entered.
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 and 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.
