It's a Hitachi V-422. I have been bidding on these forever and never managed to win any. I'm too cheap, I guess! This one looks like it will do everything I need it too! It has 2 inputs and supports up to a 40MHz signal. I have a few pet projects that require some waveform analysis of PFN's. I'm very excited about this! CAN YOU TELL??!?!?!
