vibometer

[Koye88]

Hi All,

Plz, I am looking for LabVIEW drivers for a polytec scanning laser vibrometer (using NI-5133) and

a Physik Instrumente (PI) 2-axes motor (with PI C-863 motor controller) system.

This system have to be able to perform scanning at defined intervals and

record the frequencies and amplitudes (data acquired) at each point.

I do have NI-Scope and some VIs from PI for C-863

But can NOT synchronize the motion and acquire data as defined above.

Cheers

Hi Koye88,

Thank you for contacting National Instruments. Once again, as a general tip, try to only post one issue at a time. This will make resolving your question faster as the groups effort will not be spread to lots of different people. If you find that you are not getting a satisfactory answer to your question try replying to the original post and rewording it. 

Anyway, on with trying to solve this problem. I am afraid I have no idea what a polytec scanning laser vibrometer is, do you have any datasheets? Website links? Any data that you have on this piece of equipment will help people with your issue. 

Do you have any details on the PI C-863 controller as well? As a general guide, this is the sort of information that we would like to see when trying to help you especially when using third party equipment

1. how are you communicating with these devices (RS-232, GPIB, Direct digital lines)

2. What sample rates do these devices require? E.g. what frequency is coming out of your vibrometer, what clock rate is the motor controller?

3. Do you have any documentation that came with these devices when you got them?

4. Do they have a specialised driver/programming API?

5. Are there any example programs that we could see?

If you can give us some idea of these factors we will be better able to support you. 

You mentioned that you have NI-Scope and some Vis for the C-863. I presume then you have a program that uses both of these, you should attach this to this thread so people can see what you are working on. Also, if you have a specialised library for the C-863, post a link so other people can get this and try and run your code.

You say that these devices will not synchronise; in what way? Do you mean they need to share a common clock and do the acquisition and generation at the same time? Do you simply want to start the acquisition and generation at the same time using independant time bases? Do you want one device to clock the other?

Always try and provide as much detail as possible in a forum post, particularly if it concerns non NI equipment.

Please post up some answers to these questions and your code and we shall try to help

Many thanks
