Scaling and positioning a waveform
Use the horizontal controls to adjust the time base, adjust the trigger point, and to
examine waveform details more closely. You can also use the Wave Inspector
Pan and Zoom controls to adjust the display of waveforms. See
Using wave
inspector to manage long record length waveforms on page 96.
If you push the Horizontal Position knob and Delay is set to On, the horizontal
position is set to 0 seconds. If you push it and Delay is set to Off, the horizontal
position is set to 10%.
Original waveform Scaled horizontally Positioned horizontally
Use the vertical controls to select waveforms, adjust the waveform vertical
position and scale, and set input parameters. Push a channel menu button (
1 , 2 , 3 ,
or 4 ), button as many times as needed and the associated menu items to select,
add, or remove a waveform.
Pushing the Vertical position control will center the waveform on the screen
vertically, and pushing the Vertical scale control will switch from Coarse to Fine
scaling.

Quick Tips
■ Preview. If you change the Position or Scale controls when the acquisition is
stopped or when it is waiting for the next trigger, the oscilloscope rescales
and repositions the relevant waveforms in response to the new control
settings. It simulates what you will see when you next push the
RUN button.
The oscilloscope uses the new settings for the next acquisition.
You may see a clipped waveform if the original acquisition went off the
screen.
