Figure 4-50, Using the Pulse Editor
The Pulse Editor 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 in
the middle of a pulse 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 a 0V to 3.3V amplitude, a 50% duty
cycle, and a 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 that 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.
Time/Level Points –
programs pulse turning points using level and
time markers. This format is a bit more complex to use, however, it
allows the design of pulses with linear transition times. For
example, if you want to draw a simple square waveform that has a
0V to 3.3V amplitude, a 50% duty cycle, a 1ms period and a 100ns
transition time, you enter the following parameters:
Index = 1, Level = 0, Time interval = 0, (Cumulative Time = 0)
Index = 2, Level = 3.3, Time Interval = 0.1, (Cumulative Time = 0.1)
Index = 3, Level = 3.3, Time interval = 0.4, (Cumulative Time = 0.5)
