Choose a fill pattern. The following figure shows the pattern control and the first few
signals in the window.
Tip
When generating a Marching Ones or Marching Zeroes waveform, it is
convenient to make the waveform size a multiple of the number of selected channels.

Click
Play
to generate the waveform shown in the graph on the selected channels. The
default generation option is Continuous, but you can toggle this setting using the control
below the graph.
The Play and Stop buttons are shown in the following figure.
Because the data channels on the NI digital waveform generator/analyzer are bidirectional,
while the data is being continuously generated on all of the channels, as in the previous step,
you can acquire the data being generated.
Note
Refer to the specifications for your device for information about the setup and
hold times and propagation delays associated with generation and acquisition
operations. At some frequencies, generating and acquiring data on the same channels
when no cable is attached to the DIGITAL DATA & CONTROL (DDC) connector
violates these timing parameters and results in incorrectly sampled data. For
information about proper signal acquisition, refer to the
NI Digital Waveform
Generator/Analyzer Help
.
To acquire the waveform, complete the following steps:
1.
Click the
Acquisition
tab.
2.
Click
Play
. The device acquires the digital data that you generated in the previous steps,
and the data is displayed on the graph.
