Who can explain the differences between these two models?
Thanks in advance.
7904A (500Mhz BW) uses newer "feed-forward" amplifier technology,is
more
like the 7104 1 Ghz Bright-Eye scope but without the
image-intensifier
CRT,and the chassis can be split for easier servicing like the old
7704A.
The A model replaced the older 7904.It uses the same plug-ins,same
rated
specs as the non-A model 7904.
I would not be surprised to see the average 7904A vertical BW to
reach 1
Ghz.

Yes, the 7904A is very much like the 7104 except the MCP-tube. BW is
near 1 GHz, at least mine (serial 700627 Heerenveen model) makes a nice
1.07 GHZ with -3dB down.

Oh yes, that's absolutely a must for having a spare 7904A if you want
to have these units keep working in duty ;-)
hth,
Andreas
