Index = 4, Level = 0, Time interval = 0.1, (Cumulative Time = 0.6)
Index = 5, Level = 0, Time interval = 0.4, (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 and the specified point
is marked with a red dot. Also note that the Cumulati
ve Time
column is updated automatically with the cumulative time lapse
from the start of the pulse.
Section Structure
The term Section Structure is used to define the pulse train’s
common properties. There are four parameters that can be
programmed in this
group: Index, Level, Time Interval and
Cumulative Time.
Index –
Is added automatically as you program pulse segments.
The index line is highlighted as you point and click on pulse
segments on the Pulse Editor screen.
Level – Specifies that peak level of t
he programmed segment. As
you build the pulse, the level window is expended automatically to
fit the required amplitude range.
Time Interval –
Specifies the time that will lapse for the current
index level. You can program the time interval and the cumulative
time will be adjusted accordingly.
Cumulative Time – Specifies the time that will lapse from the start of
the current pulse section. You can program the cumulative time and
the time interval will be adjusted accordingly.
Section Properties
The Section
Properties contains a summary of properties that are
unique for the current section.
Design Units – Provides
information on the units that are used
when you draw the pulse segments. These units can be changed in
the Pulse Editor options.
Section Start – Provides timing information for the start of the
current section. If this is the first pulse section the value will always
be 0. Subsequent sections will show the start mark equal to the end
mark of the previous section.
Repeat – Allows multiplication of pu
lse segments without the need
to re-
design repetitive parts. After you enter a repeat value, press
the Apply button to lock in the repeat multiplier.
Duration –
Displays the time that will lapse from the start of the
pulse section to the end. The duration
shows the total time lapse,
including the repeated sections.
Control Buttons
The control buttons allow you to append, insert, or delete
one or all
index lines. The Undo button is useful in cases where an error was
made and restoration of the last operation is critical.
