Latency between decklink studio SDI in en output?

I've search the entire website for this information, but can't find it.

Can anyone tell me what the latency is in video frames between the SDI input and SDI output connectors for the decklink studio card ?

If you are using the SDI output as a pass through from the SDI input, this is an unprocessed pass through, so the latency will essentially be nil. Keep in mind that the pass through only activates when you have compatible software open and accessing the card in a capture mode.
