To Adjust Sweep Speed And Horizontal Position - Agilent Technologies 54831A User's Quick Start Manual

To adjust sweep speed and horizontal position

• To stretch the waveform horizontally, turn the sweep speed knob
clockwise. To shrink it horizontally, turn the knob counter-clockwise.
The sweep speed knob is the larger of the two horizontal control knobs. It is
marked with a set of sine wave symbols. Stretching the waveform means there
are fewer seconds displayed per division. Shrinking the waveform means there
are more seconds displayed per division.
• To move the waveform to the right, turn the horizontal position knob
clockwise. To move the waveform to the left, turn the horizontal
position knob counter-clockwise.
Moving the waveform to the right shows more of the pre-trigger data (data
acquired before the trigger event). Moving the waveform to the left shows more
of the post-trigger data (data acquired after the trigger event).
The horizontal position knob is the smaller of the two horizontal control knobs.
It is marked with a set of arrows. There is a detent programmed into the
software so there is a momentary pause at zero while you are turning the knob.
Continuing to turn the knob will move the horizontal position through zero.
