Generating Waveforms Using the Equation Editor
Figure 4-50, Using the Pulse Editor
The Pulse Editor as shown in Figure 4-50 has four groups: Section
Structure, Pulse Train Design Format, Section Properties and
control buttons. These groups are described below.
Pulse Train Design Format
There are two methods (or formats) that can be use for designing
the pulse shape: DC Intervals and Time/Level Points. The design
format is unique for the current section and cannot be switched
during the section design.
DC Intervals – programs pulse duration using DC levels only.
Transition times for this format are at the maximum rate that the
generator can produce. For example, if you want to draw a simple
square waveform that has 0V to 3.3V amplitude, 50% duty cycle
and 1ms period, you enter the following parameters:
Index = 1, Level = 3.3, Time interval = 0.5 (Cumulative Time = 0.5)
Index = 2, Level = 0, Time Interval = 0.5 (Cumulative Time = 1.0)
Note as you build the segments that the pulse is being drawn on the
screen as you type in the parameters. Also note that the Cumulative
Time column is updated automatically with the cumulative time
lapse from the start of the pulse.
