Hello Kirbi,

Depending on which sa_api version you are running, real-time functionality has changed recently. You will want to check out the programming manual for your version to find a full C example in the appendix for setting up real-time mode. This should help you set up Labview.

I’m trying to run the updated version, but am getting an Error Code 13 right out the gate after saGetSerialNumberList. I have my SA44B connected and it works fine with Spike. I’ve unplugged to power on an off the SA several times, but can’t get the project to run.

Any ideas with error 13 is?

Thanks!

After further investigation, Error 13 is a general LabVIEW error: File is not a resource file. “Failed to load dynamic library because of missing external symbols or dependencies, or because of an invalid file format.

The VI is pointing to the correct location of the Spike DLL. Any thoughts?

Thanks!

Hello rmaso,

Someone else might be able to assist you further. I don’t have experience with Labview but I found this response earlier in this thread.

If you have installed the Signal Hound Spike application, look in this folder.
C:\Program Files\Signal Hound\Spike\api\sa_series\labview
This is a Labview example we distribute. Another forum member was able to verify this worked out of the box. If this example works for you, then maybe you can determine what is causing issues with your setup.

Check that both Labview and Spike have the same bitness (Both are 32 bit or both are 64 bit). It will not work otherwise.

How to do peak search using Signal-hound-LV2009??
I need the peak frequency from the obtained waveform.
I got it in spike software, but not in labview vi.
Can anyone help me??

Hello Ncnteam,

You will need to find the peak manually. This can be as easy as finding the maximum value in the array. A quick search shows a simple vi is provided for this type of functionality.

And it looks to be available in the base version of Labview.

Let us know if you have additional questions or if this didn’t answer your question.
