Subject: RE: Oscilloscope Recommendation
From: robert.jarratt at
ntlworld.com
I find myself in need of an oscilloscope to help me fix my PDP11 PSU
(I am being ably assisted by a member of the list, so don't worry). As
this is for occasional use only I can't justify spending a lot of
money. From previous postings on the list I think I need a minimum
spec of dual trace and 20MHz bandwidth.
Does anyone have any recommendations for what to buy? I suspect it
would be better to get a higher quality used one than a cheaper new
one. Perhaps someone in the UK on this list has one they want to sell?
Regards
Rob
Hi
You haven't stated what your intending to use it for.
In my original posting I said I wanted to use it to fix a PSU. Do you need
to know more details? If so, what do you need to know?
A couple of people have mentioned analog vs digital. I don't have strong
feelings either way. When I was a student I used analog, I have never used a
digital one, so I would be happy with whichever is going to be effective and
not too expensive. as this is only for occasional use
DSO are fine but there are good reasons to go with an
analog scope ( I
prefer
these ).
Delayed sweep and a minum of 2 channels is a must for most clasic
computer
work.

Thanks
