For other instrument driver types, the examples will be available from the Application Examples subpalette from the corresponding instrument driver. In the following figure we have opened the Agilent Read Multiple Measurements. Back to Top 2. This list can be long, so you might need to browse for keywords that match the driver, such as the vendor name or “IVI”. The class interface changes and a new set of properties and methods are now selectable, shown in Figure 6.

Examples include VIs for reading a measured lwbview or waveform and VIs for downloading waveforms or digital patterns to a source instrument. It would be extremely useful to show how to modify portions of instrument drivers for other use.
Message 2 of 7.
Using LabVIEW driver for Agilent A – Discussion Forums – National Instruments
Message 4 of 7. Generally, you need to call the Close VI only once at the end of an application or when you finish communication with an instrument. Try the link below: Message 5 of 7. Enabling autozero optimizes the instrument for accuracy, while disabling optimizes for speed.
You can create instrument control applications and systems by programmatically linking instrument driver VIs on the block diagram.
Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument 34401q palette. Message 7 of 7. Converting variant data to an array See Also: The Initialize VI- the first instrument driver VI you call, establishes communication with the instrument. The block diagram should now appear similar to Figure 2. Then the Configure Measurement VI is called to set the instrument up for the desired measurement.
Open a blank vi.
Both of these drives are supported by Agilent and come complete with example code for common tasks. Feel free afilent write us at les. Instrument Driver Organization Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette.
Back to Top 2. You should close references to all ActiveX sessions and interfaces when you are finished using them. They also have a CVI driver that can be converted. Most Active Software Boards: Works like a charm. Saying that it is straight forward is not what you want to read, right? Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument.
Don’t be afraid of experimenting.
It is a nice icon with red lettering and a tiny picture of the multimeter. Message 6 of 7. However, LabVIEW Plug and Play instrument drivers are distributed with their block diagram source code, so you can customize them for a specific application.
In this labivew, serial communication is used.
Using an IVI-COM Instrument Driver in LabVIEW
Place a checkmark in the Show Creatable Objects Only check-box to display only objects that you can create. Numerous Configuration VIs can exist, depending on the particular instrument. An instrument driver is a set of software routines that control a programmable instrument. Oabview on the block diagram to place the Initialize method on the diagram. Agilent IO Libraries Suite version The Configuration VIs- a collection of software routines zgilent configure the instrument to perform the operation you want.
