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.
• Display scan mode:
When the Time/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.
Window Zone
Use the Window Zone option to define a segment of a waveform to see
more detail. This function behaves like zooming into a portion of the
captured waveform. The window time base setting cannot be set slower
than the Main time base setting.
You can turn the Horizontal Position and Time/div controls to enlarge or
minimize waveforms in the Window Zone.
If you want to see a section of the waveform in details, follow these steps:
1. Press the “HORI MENU” button to enter the “Horizontal menu”.
2. Turn the “Time/div” knob to change the main timebase scale.
3. Press the “Delayed” option button to select “On”.
