Hi Dave,

Yep it looks like it's still available. I've seen discontinued on a distributor website which made me thinking the product wasn't available anymore.
I'll look what is the price for the HP53230A for comparison.

Cheers
Stephane

It still looks available to me
http://www.thinksrs.com/products/SR620.htm

There is also a Keysight 53230A with a slightly better (20 ps vs 25 ps) single shot resolution. It looks more modern, but I don't know how well they compare.

Dave.
