Horizontal Delay and Horizontal Position
To Use
Use the multipurpose knob or the front-panel HORIZONTAL POSITION knob to set the
horizontal position when the horizontal Delay Mode is Off.
When Delay is On, use the multipurpose knobs to set the Horiz Delay (Horizontal Delay) and the
Ref Point (Reference Point).
Behavior
The Position control moves the trigger point within the acquired waveform. Use the control to
select the amount of data that appears before the trigger event.
The Horiz Delay and Ref Point controls only appear when the Delay Mode is On. Horiz Delay
enables the instrument to look for a trigger and then wait a specified time before acquiring data.
This is useful when you know that the data you are interested in occurs a set time after the trigger.
Use the Ref Point control to specify the amount of pretrigger data. The reference point is
represented on the screen by a small inverted triangle.
Use the dedicated DELAY button to turn the Horizontal Delay on and off. Or, use the Horiz/Acq
menu
Delay Mode On
command.
Toggle Horizontal Delay on and off to quickly compare signal details at two different areas of
interest, one near the trigger location and the other centered at the delay time.
Horizontal Position/Scale Control Window
Access this control window from the Horiz/Acq menu Position/Scale command.
Overview
Use the Horizontal Position/Scale control window to set the
horizontal position and scale of displayed waveforms. You can
also use it to turn on horizontal delay so the acquisition window
can be focused on events that occur at a fixed delay after the
trigger point.
The dedicated controls on the front panel also perform the same
functions.
For information on Delay Mode control see page 99, on Position
control see page 99, and on Scale control see page 99 .
