How to connect Force Impulse hammer

[Panagis]

Hello,

I am a student and new to Labview. I am using Labview 8.5 which is installed in a NI PXI-1031. In the NI PXI-1031 there is installed the NI PXI-6132 multifunction DAQ which is connected to BNC-2110 connector. 

I started with the built in tutorials (from the getting started with Labview) and when I was doing tutorial 4: How to communicate with instruments, I faced a problem. The instrument I would like to use is Kistler 9724A5000 Impulse Force Hammer. I also have the Kistler 5108A Piezotron Coupler. When I reached the step that I had to open the ''Find Instrument drivers'' from the Help menu, there was no Instrument in the list. I had connected the hammer with a suitable cable to the coupler, I had an input  of 25V dc supply to the coupler and I had it connected to the AI3 input of the BNC-2110. I pressed F5 in order to scan for instruments several times, but the problem remained.

Could someone please tell me what am I doing wrong? Am I connecting the Hammer wrongly or am I doing something wrong with labview?

Thanks a lot

I have a suspicion that your system is outputting an analog voltage signal.

So I think you'll want to read that voltage and convert it to a relevant signal.

For that, you will probably not find an instrument driver.

You should look at the examples provided with labview, such as this one:

\examples\DAQmx\Analog In\Measure Voltage.llb\Cont Acq&Graph Voltage-Int Clk.vi

Just use the Example Finder to view other examples.

Thanks a lot Josborne, the example you told me to look worked for me after a few changes that I made. I was able to measure some impacts I did using the impulse force hammer.  I would like to ask one more question: Is there any tutorial or example or something like that concerning modal analysis on labview?

Thanks a lot

The NI website has a lot of information.  Whenever you get stuck, just go to www.ni.com and search.

Searching for "modal analysis" turns up some interesdting links like these:
