Decoding IRIG with Labview 8.0 Full Development Version

[mlnair]

I have a series of data files in which I have an IRIG time code recorded as an analog signal.  I am wondering if there are any existing VI's to decode that signal into regular time using Labview 8.0 full development version.  Let me know if anyone has any information on this one.

Thanks

I have to develop a similar program where I have input time tag given to the IRIG board and I have read this input time tag and also the time elapsed from the IRIG board to display in LAbVIEW. My idea is that I can use the Event time tag to create a event each time a time tag is inputted. But how does this board interact with LAbVIEW. I am a beginner in LAbVIEW. Please help.

Thanks in advance,

I too have a series of data files in which I have an analog IRIG B time code recorded.    I am wondering if there are any existing VI's to decode that signal into regular time using Labview 8.0 full development version.  mlnair, did you complete or find a code?  Let me know too if anyone has any information on this one.

Thanks,

Hi Yeske,

Unfortunately, I am not aware of any VI's specifically tailored to this purpose. I did, however, find an example program on Dev Zone that implements IRIG B in LV FPGA -- perhaps this could give you some insight?  Here's the link:

My only other thought (other than programming from scratch) would be to physically output the IRIG B signal and then decode it using hardware. I realize this is a pretty-involved workaround, but it might be easier than writing the code (provided you have the hardware of course!)

Hope this helps,

The last post in this thread was in July of 2006.  Does anyone have a LabView VI to decode an IRIG-B signal recorded as an analog signal and stored in a file?

Thanks,
