Horizontal Controls
Roll Mode
2-29
Roll Mode
Roll mode continuously moves data across the display from left to right. It allows
you to see dynamic changes (like adjusting a potentiometer) on low frequency
waveforms. Two frequently used applications are transducer monitoring and
power supply testing. When in the Roll Mode, the oscilloscope is untriggered
and runs continuously. You can also make automatic measurements in the roll
mode.
The oscilloscope automatically enters the Roll Mode when the Horizontal Scale
control is set to 50 ms/div or slower and the trigger sweep is set to Auto.
