Agilent has oscilloscopes to 63 GHz /160GS/s. How is that possible?

JoeN:
What type of technology is used to make such a ($439,824) product? How do you sample at that rate? 160GS/s implies some sort of clock at 160Ghz. How is that done? I don't understand how this can be done at any price the speeds are so otherworldly.

Are you sure you don't mean a spectrum analyzer? I am at Agilent's site now and don't see any scopes like that.
