In practice I can see the full edge of my 700 ps PG506 across some 4 full divisions (Fast Variable Persistence at Reduced Scan, or Fast Transfer Mode). It shows as about 1.1 nsec. Admittedly, these are very specific cases but I wouldn't call this mode particularly annoying to use, especially on a 7834 or (slower) on a 466.
same reason; it was the least expensive way to get 400 MHz single shot
capture performance. For repetitive applications however, variable
persistence mode is much easier to use.
Getting back to the original topic, if I was limited to one 7000
mainframe, then it would be one of the variable persistence models. If
I was limited to two 7000 mainframes, then one of them would be a
variable persistence model. But the fast transfer modes would not be
