GPIB newbie question

[Sreedhar Tatavarthi]

I am trying to write my first GPIB based application.
Can somebody give me some pointers to good examples of GPIB using
LabVIEW.(Could not find any on Development Library of NI)

I did have one example with me, which just reads data from
oscilloscope. This has some some commands like "READ, C2.DA" wired to
the "data" terminal of GPIB Write function. Similarly it also has
":TIMebase:DElay?". How can I know more about such commands? I
searched a lot for these, but could not find any resources.

Thanks
Sreedhar

Sreedhar,

Unfortunately, I can't recommend much in the way of GOOD GPIB applications, as I am wholly unsatisfied with the quality of National Instruments' instrument drivers for various instruments (with regards to style). However; instrument drivers are going to be your best bet for examples. Try the instrument driver CD that comes with LabVIEW, or download some from the NI website.

GPIB is merely a form of communication. As such, the applications should be very simple.

Hopefull that helps.

The first place to start is Chapters 18,19,20 of the LabVIEW Measurements Manual. This is a .pdf file that ships with LabVIEW. In the Development Library, there's a couple of links. Check out What is an Instrument Driver, Using IVI Drivers in LabVIEW , and LabVIEW IVI Class Sample Programs. The commands you mention are what are sent to the instrument to program it. The commands are unique to e
ach manufacturer and to each instrument. You need to look at the instrument's programming manual to learn the particulars of it's command set. It is much easier to start with an instrument driver because it hides a lot of the complexity and you won't have to do nearly as much debugging.

Sreedhar,
The first place I would look is the instruction manual for the instrument.
There should be a section on GPIB commands. All of the possible commands
will be listed. There may be a separate manual for the GPIB operation.
Hope this helps.
