Identifying Items in the Time Domain Display
The items shown in the graphic below may appear in the display. Not all of these items are visible at any given time. Some
readouts move outside the graticule area when menus are turned off.
1. The acquisition readout shows when an acquisition is running, stopped, or when acquisition preview is in effect. Run =
acquisitions enabled. Stop = Acquisitions not enabled. Roll = roll mode (40 ms/div or slower). PreVu = The oscilloscope
is stopped or between triggers. You can change the horizontal or vertical position or scale to see approximately what the
next acquisition will look like. A/B = When using the average acquisition mode, B shows the total number of acquisitions to
be averaged (set this using the Acquisition Mode side menu), and A shows the current progress towards this total number.
2. The trigger position icon shows the trigger position in the acquisition.
3. The expansion point icon (an orange triangle) shows the point that the horizontal scale expands and compresses around.
To make the expansion point the same as the trigger point, push
Acquire and set the lower menu Delay item to Off .
