[sdiy] Owon scope oddity...

Its not just the oscilloscope.  x1 probes also have a much narrower 
bandwidth due to the capacitance Robin mentioned.  For example, looking 
at the ProbeMaster 3900 range, the x1 probe has a 26MHz bandwidth, the 
x10 probe has 100MHz bandwidth, and the switchable x1/x10 probe has 
10MHz at x1 and 100MHz at x10.

That's interesting...

...so is it possible to say whether it's my scope limiting the bandwidth or the probes when set to x1?

Or to put it another way -  if I was to upgrade my probes e.g. to the x1 3900 you've mentioned above - would I get the full 25MHz bandwidth of the scope back (or thereabouts) at x1 setting?

For the record, it's been a perfectly adequate scope - but I am interested in seeing if I can push it a bit further...

Thanks!
