Generating Waveforms Using the Equation Editor
3-61
The force pulse sections to multiple segments option will place each
section of the pulse train into a different memory segment and the
generator will automatically be set to operate in sequenced mode.
Select this option for the example we are going to build later.
If you are not sure what to do, select the freely select mode of
operation and the generator will do the work for you.
Design Units
As you design your pulse pattern, it will be easier if you design it
using the exact units as you would want to output to your load.
Select between
μ
s, ms and s for the pulse intervals and mV or V for
the amplitude level. Select ms and V for the example we are going
to build later.
Memory management
There are two options in the memory management group.
The do not override loaded segments option will make sure that
whatever waveforms you already stored for the arbitrary function
will stay intact after you save your pulse waveform.
The allow pulse design with no limitations option may overwrite
memory segments that you already used previously for the arbitrary
function however, this is the recommended option for the program
and for the example we are going to build later.
Pulse Transition management
The pulse transition management parameter defines for the
program how many waveform points will be used to step from one
amplitude level to another amplitude level. The longer the transition
time, the program will need more steps to smooth the transition. If
you select the limit increments and set a pre-defined number of
increments, you manually control how many waveform points will be
dedicated for transitions however, if you are not sure what is the
optimum number of increments, select the allow system control
option for the program to make the transitions efficient in terms of
memory usage and slope smoothness.
After you complete setting the pulse editor options, point and click
on OK.
Using the Pulse Editor The prime tool for building pulse patterns on the pulse composer
screen is the pulse editor. To invoke the pulse editor, point and click
on the pulse editor icon on the tools bar. The editor as shown in
Figure 3-46 will show. Refer to this figure for the following
descriptions.
