Does anyone happen to know when the follow Tek scopes were released?
-- The Tek 519, which I believe was the first Tek scope with 1GHz bandwidth; apparently released in the mid-60s.
-- The Tek 11801 along with the SD24 sampling head; apparently released in the early-'90s. I'm actually after when the first ~20GHz sampling scope become available.
Thanks,
