Acquisition interval

The acquisition interval is the time between sample points. For mathematical purposes, it is the time covered by the waveform

record divided by the record length.

FastFrame control windows

From the Horiz /Acq menu, select FastFrame Setup.

Overview

Use the FastFrame control windows to capture and view a series of triggered acquisitions without wasting acquisition memory on

the dead time between the trigger events.

NOTE. On DPO70000SX instruments, FastFrame is not available in multiscope mode.

For information on the controls, click the buttons.

Behavior

FastFrame mode combines multiple acquisitions into one large data record. By carefully defining the trigger conditions, you can

use FastFrame to capture only multiple events of the waveform that you are interested in. Each captured event is stored

sequentially in its own frame. The frames are in the order they were captured.

FastFrame mode lets you jump to and view the desired frame. Time Stamps can display the absolute trigger time for a specific

frame and the relative time between triggers of two specified frames. FastFrame lets you compare different waveforms. Math is

performed on each frame.

FastFrame provides the following features:

■

Measure time between triggered acquisitions using time stamps in Sample, Peak Detect, and Hi Res mode.

■

Save and recall FastFrame waveforms.

■

Display waveforms in YT mode.

■

Apply math functions to FastFrame waveforms.
