Programmatically Enabling the Output on a NI PXIe-4610 Amplifier

Updated Jan 7, 2021



  • LabVIEW


  • NI-DAQmx

There are two ways to enable NI PXIe-4610 outputs. This article will go through how to programmatically enable the outputs using LabVIEW. 

You will need to have installed LabVIEW and NI DAQmx. 

To enable the output you need to use the DAQmx Physical Channel Property Node.

1. Place a DAQmx Physical Channel Property Node on the Block Diagram.
2. Drag it down to show 2 properties and set these as ActivePhysicalChans and AO.PowerAmp.ChannelEnable, as is shown in the image below. 
3. Right-click the ActivePhysicalChans input and select Create Constant.
5. Right-click the constant you just created and go to I/O Name Filtering...>>I/O Type and change the type to Analog Output.
6. Click the constant and select the correct output. 
7. Right-click the AO.PowerAmp.ChannelEnable and select Change All To Write.
8. Wire a true constant into the AO.PowerAmp.ChannelEnable.

After following the steps above, you can run the VI, which will enable the amplifier output. The VI should look like the image below.

If you would like to control a different output channel, duplicate the property node, and change the ActivePhysicalChans to the output channel you require.
