The type of equivalent-time sampling the instrument uses is called random equivalent-time
sampling. Although it takes the samples sequentially in time, it takes them randomly with respect
to the trigger. Random sampling occurs because the instrument sample clock runs asynchronously
with respect to the input signal and the signal trigger. The instrument takes samples independently
of the trigger position and displays them based on the time difference between the sample and the
trigger.
FastFrame Setup Control Window
Access the FastFrame Setup from the Acquisition tab of the Horizontal Setup control window.
Control Window Overview
Use these controls to capture a series of triggered acquisitions at high resolution without wasting
acquisition memory on the dead time in-between the trigger events.
FastFrame mode combines multiple acquisitions into one large 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 done on each frame.
FastFrame provides the following features:
