The Pulse Composer is a great tool for creating and editing pulses
without the need to think about sample clock, number of points and
complex equations. Pulses are created on the screen, simply and
efficiently in a special dialog box by typing in the width and level, or
by using the "rubber band" method to place straight line segments
with the exact amplitude and time duration. The pulse composer
can also multiply pulse sections to create pulse duplication along
lengthy time intervals.
When you finally have your pulse design on the screen the program
determines if the pulse design will fit in one memory segment or use
multiple segments and employ the sequence generator for
repeatable segments. In either case, bear in mind that if you
already have some waveforms stored in memory segments, these
will be erased to make room for the new pulse design. If you insist
on keeping arbitrary waveforms and still download complex pulses,
you can check the "Force pulse to one segment" option and the
2074 will do some extra "muscle flexing" to fit the pulse as required.
To launch the pulse composer point and click on the Pulse tab in
the Panels bar. Figure 4-43 shows an example of the pulse
composer. The Pulse Composer has three main sections:
Commands bar, Toolbar and Waveform screen. Refer to Figure 4-
43 throughout the description of these sections.
The commands bar provides access to standard Windows
commands such as File and View. In addition, there are
ArbExplorer-specific commands such as Edit, Wave and System.
In general, clicking on one of the commands opens a dialog box
with an additional list of commands. Then, clicking on an additional
command, may open a dialog box, or generate an immediate
action. For example, Clicking on File and then Exit will cause an
immediate termination of the Pulse Composer. The various
commands in the Commands bar are listed and described below.
