Setting a Property in an IVI-C Driver

Properties such as Trigger Delay can also be set (and read) with a property node.

This is important in cases where a configuration function is not provided by the

driver.

For example we can replace steps 4 and 5 of the “Configure the Instrument”

section with:

1 From the Functions palette select Application Control and drop a Property

Node on the Block Diagram.

2 Connect the resource name and error information from Configure

Measurement VI to the Property Node.

3 Right-click on the Property Node and select Change All to Write.

4 Click on the Property field and select Trigger >> Trigger Delay.

Using IVI-COM

To use IVI-COM drivers in LabVIEW you will use the ActiveX functions and the

Class Browser that are built-in to LabVIEW.
