From your perspective, what makes the 2445 a better scope than the
2236,
aside from the number of channels and bandwidth?

Thanks, Michael


2445/65 series scopes were the most accurate analog scopes made.Better
triggering.It has nifty cursor measurement modes,too.The 2445/65 series
were essentially lab quality portable scopes.They were meant as a
replacement for the 485,with added features.

There also were some very useful options,and the counter-timer option was
more accurate than the counter in the 2236. The 2245/65 DMM option was far
better than the 2236 DMM. 2445/65 had a TV trigger option with line
counting.When it concerns counters,one has to consider the time-base
accuracy,otherwise all those digits are meaningless.


The 2200 series was intended as low-cost,high production volume scope,with
poorer triggering than a 465/475 series scope. The DMM counter module was
for field service people so they would not have to carry a DMM and a
counter with the scope,reducing their equipment load,reminiscent of the 213
1Mhz portable scope/DMM,but muuch more useable.
