Hi all,

On my bench I use a 100mhz dual trace digital scope.  I also own a 15mhz NS
215 miniscope. As a general rule, figure you need 10x bandwidth to
effectively use a scope. You can get by with 5x bandwidth. I find this to be
true regularly.  Recently I was working on a project with a 15mhz to 20mhz
oscillator and found although my scope was adequate, it was definitely
pushing it as the trace was not as clean and precise as I like. The signal
was not even readable on my 15mhz scope.

So, a 5mhz scope, in practice, is VERY usable up to about 500khz, and usable
up to about 1mhz.  Considering, that in most cases, you are working with
signals below about 30khz, 5mhz should be adequate.

Looking at the pdf, it has a knob for trigger, so, I assume that it IS a
triggered sweep scope, which is good. I think if you want something that
will have a chance at fitting in your rack, this is probably the only
choice.

My only caveat would be that if you think you may want to build modules, or
use a scope for other reasons, this is a fairly limiting model.  But, as a
module to make it easy to see what's happening, it will work just fine.
