Using the Oscilloscope
Adjusting the Horizontal Time Scale and Trigger Position
Use the horizontal controls to configure the oscilloscope’s horizontal scale
(time per division) and horizontal position of the waveform. You can also
view a magnified section of the waveform using the zoom window.
You can use the horizontal scale and position knobs, the horizontal GUI
controls, or the Horizontal Setup dialog box to adjust the horizontal scale
and position.
Adjusting the horizontal scale
• To stretch the waveform horizontally, turn the horizontal scale knob
clockwise. To shrink it horizontally, turn the knob counter- clockwise.
The horizontal scale 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.
Push the horizontal scale knob to change the scaling in finer (Vernier)
increments.
