Subject: | How to Select a Scope |
I've been considering purchasing an oscilloscope for hobby/trouble-shooting
use. It's been 30+ years since I've fiddled with scopes. I'm looking for
counseling/guidance/recommendations.
Some things I want to do:
1. Analyze the output of the crank angle sensor in my car - (currently
having some starting problems, but I digress)
2. I like to program micro-controllers and would like to do
trouble-shooting & analysis
3. Look at the wave-forms produced by an alternator
4. Get the best bang for the buck
Questions:
1. I see devises advertised that are combo oscilloscope & logic
analyzer. Are these as cool as they appear?
2. How do I decide which frequency range I need? (It seems the higher
the MHz rating of a device the higher the cost) Most of the
micro-controllers that I work with are clocked around 4 MHz. I once heard
that the rating of the scope should be 10x the signal you want to analyze.
Is that true?
3. What other criteria should I consider?
As always TIA, I look forward to learning something

Subject: | Re: How to Select a Scope |
I have one of these:
http://www.tequipment.net/RigolDS1102E.html
It's "good" -- it's a pretty good scope for $400. Digital, storage, USB
image and data capture, RS-232/USB computer control port.
You can also get a DS1052E for $350 if you want to drop down to 50MHz
bandwidth for $50 less. I ended up getting the scope case for $50 as
well.
There are definitely some glitches and usability hitches every now and
then, but overall it's great for the money. But, if I had tons of money
to blow, I'd definitely get an Agilent Infiniivision scope.
For the microcontroller work, you're going to get a lot more
productivity mileage out of a Saleae Logic:
http://www.saleae.com/logic
For $150 not only will it capture 8 channels in parallel, but you can
also assign channels to be decoded inline. Many serial formats are
supported out of the box. For digital work, I highly recommend it. It
will not read any analog inputs, however, so you'd need a scope for that
-- but getting that kind of serial decoding in a scope tends to be
expensive.
Good luck!

saelig.com is worth a look for value. I have an older PDS5022S which is
about all I need for playing with microcontrollers etc.

Thanks for all responses. Most have dealt w/ actual O-scopes.
What about scope/analyzers that connect to a computer via USB for control &
display?
