5.2 Horizontal Controls
Use the horizontal controls to change the horizontal scale and position of waveforms. The
horizontal position readout shows the time represented by the center of the screen, using the
trigger time as zero. When you change the horizontal scale, the waveform will expand or contract
to the screen center. The readout near the upper right of the screen shows the current horizontal
position in second. M represents ‘Main Time Base’, and W indicates ‘Window Time Base’. The
oscilloscope also has an arrow icon at the top of the graticule to indicate the horizontal position.
