An instrument driver is a set of software routines that control a programmable instrument. Links to complete examples demonstrating how to execute the Measurement method and read the measured value are provided at the end of this document. The best way is to open the sub-vi which appears to be what you want to do and run it. Message 6 of 7. Click on the block diagram to place the Initialize method on the diagram. An instrument driver is a set of software routines that control a programmable instrument.

The Configuration VIs- a collection of software routines that configure the instrument to perform the operation you want.
Instrument drivers labvieew instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument. Selecting a dotted property. I download directly from Agilent’s website. Saying that it is straight forward is not what you want to read, right?
Message 2 of 7. A dialog box appears, shown in Figure 1. Make sure that for each successful call to the Initialize VI, you use a matching Close VI to avoid maintaining unnecessary memory resources.
Figure 10 34401z the Context Help window for the AutoRange property. This tool searches IDNet to find the specified instrument driver. For other instrument driver types, the examples will be available from the Application Examples subpalette from the corresponding instrument driver. Viewing context help for AutoRange property.
Agilent 34401 Meter
Get acquainted with sub-vi’s. Most instrument drivers have menu palettes that include the following components. You should consider all driver choices available, and choose the driver that best fits your needs.
The 34401z figure shows this palette and some of the VIs and subpalettes that are shipped with it. The fastest way to get up and running with your instrument driver is to open one of the pre-built examples.
The native driver has help for each of the instrument functons if you use the F1 help mechanism.
This is typically the first interface in the list. Selecting help for Initialize method. In this example, serial communication is used.

Refer to the instrument driver help to labbiew the array data type. You also can use the Instrument Driver Finder to open example programs covering everything from analysis and presentation to using your instrument driver.
Message 6 of 7.
Les Hammer Complete Test. Once the measurement is complete, the Close VI is called which performs an instrument error query and terminates the software connection to the instrument.
Using an IVI-COM Instrument Driver in LabVIEW
You can create instrument control applications and systems by programmatically linking instrument driver VIs on the block diagram. Place a checkmark in the Show Creatable Objects Only check-box to display only objects that you can create. After you call these VIs, the instrument is ready to take measurements or to stimulate a system. Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument.
Many instrument drivers have a VI Tree VI you can use to view the entire instrument driver hierarchy.
