To verify your device configuration, use the device test panel in MAX to generate simple digital data using the PXIe-6544/6545/6547/6548.
- Remove any signal connections to the device.
- Right-click the device under the appropriate Chassis, and select Test Panels.
- Select the Dynamic tab on the side of the pane.
- Click Select All to select all of your channels. The digital waveform now appears in the graph.
- Enter the frequency in the Clock Frequency control, located on the left side of the test panel.
- Enter values for the generation and acquisition voltages in the controls below the Clock Frequency control. You can enter High and Low values to create your own custom levels for the device.
-
Choose a fill pattern. The following figure shows the pattern control and the first few signals in the window.

Note When generating a Marching Ones or Marching Zeroes waveform, 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.
Because the data channels on the PXIe-6544/6545/6547/6548 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 document for information about the setup and hold times and propagation delays associated with generation operations of the device. At some frequencies, generating data on the same channels when no cable is attached to the DIGITAL DATA & CONTROL connector violates these timing parameters and results in incorrectly sampled data. For information, refer to the NI-HSDIO User Manual.
