Changing the horizontal scale causes the waveform to expand or contract
around the screen center.
• Horizontal “POSITION” knob
1. Adjust the horizontal position of all channels and
math waveforms (the position of the trigger relative
to the center of the screen). The resolution of this
control varies with the time base setting.
2. When you press the horizontal “POSITION” Knob,
you can set the horizontal position to zero.
• “time/div” knob
1. Used to change the horizontal time scale to magnify
or compress the waveform. If waveform acquisition is
stopped (using the RUN/STOP or SINGLE button),
turn the time/div knob to expand or compress the
waveform.
2. Select the horizontal time/div (scale factor) for the
main or the window time base. When Window Zone is
enabled, it changes the width of the window zone by
changing the window time base.
