Hi Brusque,

the 407 was in development when I left, the 1507 was up for the first
"facelifting", they differ mainly in bandwidth of the analog section.
Now a 507 has surfaced, it will be doing 50 MHz of analog bandwidth.
The 407 (and the 507) will have 100 MSample/sec when only one channel is
used, and the 1507 has 200 MSamples, so it is not really 150 MHZ you see
in this digital mode. Both have 2000 points of memory for each trace. so
a long serial data stream would not fit very good. I have worked with a
stream of 203 bits, and for this it was OK, for longer bitstreams I
would use a PC - provided the basic voltage level and timing is OK - to
read them back.

Of course I would prefer the 1507 to the 407, but then I mostly use it
for analog measurements, and I value the bandwidth.
One more difference: The 1507 features a doubly accelerated CRT, the 407
a single accelerated CRT (with no 14 KVolts present).

Hope this helps...
