PXI-4065

[Cosmica]

I would like to know how PXI-4065 works. I was trying to do a function in labVIEW that reads information from a pxi-5412. Is that possible? I need to test if pxi-4065 is reading information. 

Thank you,

Hi Cosmica, If you just want to verify the cards are working the fastest way is using soft front panels. If you want to code your own application you can start with the example projects that exist in your CVI (or LabView) installation folder under "samples>niDMM" and "samples>niFgen". For these folders to appear you should install NI-DMM and NI-FGEN drivers first. It is generally a good practice to install drivers first and to install the hardware later. By the way, this is the LabWindows forum. You may get see more detailed posts in LabView forum. Hope this helps.

I am going to try that. Thank you!

I tried to run one of the samples of niDMM, but they are only compatible with pxi4072, they are not compatible with pxi4065. Is there anything I could change to run it?

Thank you,

Hello Cosmica,

Thanks for your post back!

The 407X series has a different mode that the 406X series did not have. The 407X can be put in a digitizer mode so that you can acquire at higher rates. So a good example to use for your 4065 is Cont Acq & Chart Multiple Samples.vi.  You can find this example by opening the example finder in LabVIEW by going to Help >> Find Examples. Navigate to  Hardware Input and Output >> Modular Instruments >> NI-DMM >> Multi-Point Measurements >> Cont Acq & Chart Multiple Samples.vi / Acq & Chart Multiple Samples.vi. Let me know if this works for you as I have used this program here on my machine with out any problems. 

Cheers!

Corby_B,

I did try running that vi, but it seems no to read the pxi 4065. Even when I unplug the input cable in the pxi 4065, it keep outputing the same thing. And, I did other testings and I reads the pxi 4065. Maybe I am just confused. What I am trying to do is to ouput a waveform graph.

Thank you,

Cosmica

Cosmica,

I could not understand your situation from what you have written.

Have you ever made a successful reading with your DMM? If yes, did you use a tool or write your own code for this?

If no, have you ever run the Measurement & Automation Explorer after you installed the DMM? If you did not, run it and check the device descriptor for your DMM.

The example suggested by Corby probably requires this device descriptor string to decide which device to operate on.

Corby may comment on the behaviour of the example weather it detects the device automatically.

I'm not sure you are experienced with PXI instruments or not. So if you clarify your situation, we may help you better.

Ebalci,

Sorry for the confusion, yesterday I figured out how to solve the problem. It is reading correclty now. Your are right, I am really trying to get familiar with the pxi drivers.

Thank you for your reply,
