If you can afford it get the HPS-40. The main limitation on any scope is the
sample rate. Eventually you will want to debug a problem that requires a
higher sample rate.
The other reason is that although the frequency you are looking at can be
handled by the 10MHz scope, you may say, have a glitch or noise whose
duration is shorter than the sample rate of the 10MHz scope.

Subject: [mach1mach2cnc] Oscilloscope question...
Hi,
I need some help from experts.
I have possibility to have handheld oscilloscope from Velleman.
There is two models:
HPS10 and HPS40
The difference betveen these two is maximum sample rate ( 10MHz
versus 40MHz ).
And also HPS40 have adjustable trigger level ( in 8 steps ).
My need is check encoder pulses ( TTL and Differential 5V ) and
DC voltage riple.
Any advise which one I should get?
HPS40 is more expensive but is HPS10 enough for use I descripe above?
Regards Mika
