VISA or IVI drivers, example code?

[jto2]

Hello,

I have an Agilent DSO-X-2004A oscilloscope and I've downloaded two different set's of drivers that work. Here are the links to the drivers.

The first one is the Agilent 2000 3000 4000 X-Series drivers, that require only NI VISA-4.6

The second is the Agilent agx2k3k Oscilloscope drivers, that require NI VISA-4.6 or IVI Compliance 4.3

The second one has example codes, which are VERY helpful for me since I am new to LabVIEW. The first one does not have examples, but seems to have more thorough driver library with more scope options to set. Without the examples though, I will have a tough time. Can I find examples for those drivers somewhere?

When mixing blocks from different drivers, I get broken wires with the message "source is IVI session of class, sink is VISA session of class". Maybe if I could resolve that, I could mix the driver blocks.

Thanks

The answer is that both driver sets have example code in their .zip files. The first one (Agilent 2000 3000 X-Series) just didn't have the examples show up in the Instrument I/O palet, and the other one (agx2k3k) did. You can add the examples to the palet by following the instructions here:

The question of which set to use is still open. The Agilent 2000 3000 X-Series drivers are "Certified LabVIEW Plug and Play (project-style) Instrument Drivers", and the agx2k3k dirvers are "Certified Multi-Enviornment IVI Instrument Drivers"

For a new user like myself, it's very hard to know the differences and how they may effect me down the road. Hopefully someone with more experience can chime in.

Project driver examples are available in the same way as all other examples - Help> Find Examples.

IVI drivers from NI are written in C and you cannot easily edit them. Nor can you mix IVI and LabVIEW functions.
