2.7.1 Horizontal Control Knob
You can 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 time of the trigger as zero. 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.
■“S/div” Knob
1. Using 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 S/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.
■ Display Scan Mode：
When the SEC/DIV control is set to100 ms/div or slower and the trigger mode is
set to Auto, the oscilloscope enters the scan acquisition mode. In this mode, the
waveform display updates from left to right. There is no trigger or horizontal
position control of waveforms during scan mode.
2.7.2 Window Zone
Use the Delayed option to define a segment of a waveform to see more detail. The
Window time base setting cannot be set slower than the Main time base setting.
You can turn the Horizontal Position and SEC/DIV controls to enlarge or minish
waveforms in the Window Zone.
“M” Mean main time base, “W” mean window time base.. It is also a arrow on the
scale top to show the vertical position.
