IRIG timestamp translator for use with GPIB or VXI?

[drfunk]

Thanks in advance for looking at my question,

I have a control system consisting of a VXI mainframe, GPIB bus, and a laptop running Labview that I need to loosely synch up with another system.  The technicians are able to provide an IRIG signal, but so far I am baffled as to how I will convert it into something usefull  (I don't think I have the overhead to decode IRIG on the fly with a analog input).

In my mind I'm looking for an:

IRIG receiver that is gpib equipped,

a VXI card that acts as an IRIG decoder,

or a PCMCIA card acts as an IRIG decoder.

Any suggestions?

IRIG is so common, I have to be making this harder than it is, right?

Thanks again...

drfunk,

To decode IRIG-B, we offer the NI PXI-6608. This device allows you to perform either software or hardware timestamping. In software timestamping, a function call returns the current value of the IRIG-B signal. In hardware timestamping, a clock (or some other TTL signal) causes the current timestamp to be buffered for later software reads. There are 2 such decoders on the 6608, allowing you to timestamp 2 TTL signals with the same IRIG-B source, or to have 2 independent IRIG-B sources. I would use the 6608 in a PXI chassis with a VXI to PXI, MXI-2 bridge.

Hope this helps,

Thanks for the reply,

That is a solution, albeit a prohibitively complicated and expensive one.

The closest thing I've found to a simple VXI solution is from a 3rd party vendor:

it also seems like many mil-spec-1553 cards often come with IRIG translators.

Still looking for a cheap and dirty solution though...
