Waveform Editor
You can use the Waveform Editor shown in Figure 1-11 to create a custom
waveform. To launch the Waveform Editor, select Start»Programs»
National Instruments FGEN»Waveform Editor. You can select
waveforms from the function library, write equations, or draw them
manually. Each segment can have more than one waveform component in
it, and you can perform a variety of math functions on each component.

This soft front panel is resizable so you can view the waveforms you create
with as much precision as you wish. You can save the waveforms in the
following formats:
with as much precision as you wish. You can save the waveforms in the
following formats:
•
Voltage (
.wfm

•
Text (
.txt

•
Binary (

Text waveforms are the only format you can use with the NI 5401, and they
must contain exactly 16,384 samples to function properly.
