Frame Setup
To Use
Click the FastFrame button to turn the FastFrame mode on and off. Use the multipurpose knobs to
select the number of samples per frame and the number of frames.
Click the Selection Controls button to display only the Selected Frame controls and the Reference
Frame controls adjacent to the full-screen graticule.
Select Average or Envelope from the Summary Frame list to replace the last frame with one that is
the computed average or envelope of all frames in the set.
Behavior
The Frame Length is the record length and defines the number of samples in each frame.
The Frame Count defines the number of frames to store in the acquisition memory of a single
channel. The product of the frame length and the frame count is constrained within the available
memory. If more frames are needed, the instrument will automatically decrease the record length;
if more samples are needed, the instrument will automatically decrease the frame count.
Note
Because of overhead associated with each frame, the maximum number of frames that can be
obtained from a given record length is less than what is theoretically calculated.
