Action VIs are different from Configuration VIs because they do not change the instrument settings but order the instrument to carry out an action based on its current configuration.
After you call these VIs, the instrument is ready to take measurements or to stimulate a system. Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument. It would be extremely useful to show how to modify portions of instrument drivers for other use.
Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument. I don’t know which driver you are using, so it is difficult to send you an pabview. Get acquainted with sub-vi’s. Then the Configure Measurement VI is called to set the instrument up for the desired measurement.
I’m not sure about instructions, but if you installed the driver and opened 3441a library, you will get sub-vi’s which have a particular application purpose. Try the link below: Numerous Configuration VIs can exist, depending on the particular instrument.

In the following figure we have opened the Agilent Read Multiple Measurements. Generally, you need to call the Initialize VI only once at the beginning of an application. The Data VIs- transfer data to or from the instrument. The following figure shows this palette and some of the VIs and subpalettes that are shipped with it. labviea
I hope not to offend NI people http: The labviwe driver has help for each of the instrument functons if you use the F1 help mechanism. Open a blank vi.
The best way is to open the sub-vi which appears to be what you want to do and run labvies. Both of these drives are supported by Agilent and come complete with example code for common tasks. Most instrument drivers have menu palettes that include the following components.

Works like a charm. It is a nice icon with red lettering and a tiny picture of the multimeter. Message 7 of 7. These VIs include the majority of the instrument driver template VIs, such as reset, self-test, revision, error query, and error message.

Les Hammer Complete Test. Examples include VIs for reading a measured value or waveform and VIs for downloading waveforms or digital patterns to a source instrument. Message 6 of 7. This example shows how to configure a measurement and take multiple readings. Finally, the Simple Error Handler is called which indicates whether an error occurred. Most Active Software Boards: I download directly from Agilent’s website. After the instrument has been configured, the Read VI is used to read multiple points.
Back to Top 2. Overview of Instrument Drivers An instrument driver is a set of software routines that control a programmable instrument. Many instrument drivers have a VI Tree VI you can use to view the entire instrument driver hierarchy. This tool searches IDNet to find the specified labvuew driver.
