The Waveform
Screen
Waveforms are created and edited on the waveform screen. Figure 4-
24 shows an example of a waveform created using the equation editor
and the anchors to limit generation of the waveform between points
100 and 900. The various elements of the waveform screen are
described below.
The waveform screen has two axes – vertical and horizontal. Both
axes are divided into points.
The vertical axis is labeled from –16, 383 through 16,384 for a total of
32,768 point. This number represents 16 bits of vertical resolution and
cannot be changed because it is critical to the range of which the
3156B operates.
The horizontal axis, by default has 1000 points (from point 0 to 999).
This number can be changed using the Wave Length field in the
Toolbar. The maximum length depends on the option installed in your
instrument. The wave composer will let you define the horizontal axis
to a maximum of 1Meg words).
