2 Using the Oscilloscope
Adjusting the Horizontal Time Scale and Trigger Position
Use the horizontal controls to configure the horizontal scale (time per division) and
horizontal position of the waveform. You can view a magnified section of the
waveform using the zoom window.
Use gestures on the touch screen to adjust the horizontal scale and position. You
can also use the horizontal knobs, horizontal controls, or Horizontal dialog box.
Adjusting the horizontal scale
• The horizontal scale knob is the larger of the two horizontal control knobs. To
stretch the waveform horizontally, turn the horizontal scale knob clockwise. To
shrink it horizontally, turn the knob counter-clockwise.
Stretching the waveform means fewer seconds are displayed per division.
Shrinking it means more seconds are displayed per division.
• Push and turn the horizontal scale knob to change the scaling in finer (Vernier)
increments.
