Hoping someone can help with using this.

I was going through some boxes from a friend who had passed and left this for me. It doesn't have a manual, and I just wanted to test it to see how it works. I tried plugging it into my laptop via the USB cable that it had, but doesn't seem like it is plug and play and possible that could just be for charging. It has what appears to be a bnc connection as the only other spot that can plug into it. Any info would be great.
