Hi all,
Please accept my applogies if this isn't the correct group in which to
post this question...
I am looking to purchase a entry/mid-level O-scope and have been eyeing a
BK precision 2125A (30Mhz, Dual Trace, Analog).
http://www.testequipmentdepot.com/bk-precision/oscilloscopes/2125a.htm?gclid=CKq61L7h2ZYCFQNvHgodDnLe2w
I have tried to find some reviews on the web (and other newsgroups), but
to no avail. All I find are retailer descriptions and specifications. It
seems like a good piece of equipment for the price. I was wondering if
any of you have any experience with this box and would be will to share
your experiences with it...good or bad. If I'm going down the wrong road
on this, would you recommend another path?
As an aside...
I will also be looking into a soldering/desoldering station at some point
soon. I am rather confused as to what would be a good mid-level system. I
do conventional board work, but hope to venture into the SMT arena.
Something in the $250 +/- range. Any thoughts?
Thank you for any help you can provide...
All,
Ah, this has been a wonderful (albeit it crash course) experience about
DSO's.
I have an old Tek 2235 (100Mhz/ analog) that I got a few years ago, but it
is showing it's age (dim display, pretty worn out probes). I was thinking
that instead of trying to bring it back to life that I would invest in a new
scope - with a warranty and all. As Phil pointed out, I'll probably keep my
analog around for it's useful characteristics. But the DSO's seem to posses
some features that will come in handy as I further my studies.
The two that I'm looking at right now are these:
http://www.testequipmentdepot.com/instek/oscilloscopes/gds-1042.htm
and
http://www.tequipment.net/RigolDS1052E.html
The Instek has a lower sample rate and point storage memory, but a far
better warranty (limited lifetime), versus the Rigol, which has a higher
sample rate and memory, but a much lesser warranty...3 years, from what I
can figure.
Since I'm not that versed in these, I may not be comparing apples to apples
here. Is "memory depth" the same as "memory length?" The Rigol has 1 Mpts
(points) as opposed to the Instek's 4 K (length). Seems like a HUGE
difference there.
Thank you for your time everyone. I really do appreciate it....

I have a Rigol DS1102C that I really like. Go for the deep buffer, Rigol
makes a nice scope. I suggest spending the extra $200 for the 100MHz
version if you can afford it.
Ok. I'm going to go the distance and get the 100Mhz unit - I was thinking"sbrehler" <sbrehler@mndspring.com> wrote in message

Wow, these things are just geeting cheaper and cheaper by the month it
seems.
50MHz 1GS/s and 1MB sample memory for $535 seems insanely cheap.
Yes, there is a huge difference in memory there, but reading the specs of
the Rigol you can figure out what they have done to keep the price down.
It only has 16KB of memory at the full 1GS/s (8KB/channel for two
channels) and 1MB of "slower" memory that works at 500MS/s and lower.
That's still going to be very very useful in practice.
Memory depth and memeory length are the same thing. But some like the
Rigol will divide that up among channels, the Instek does not do this.
The extra memory, extra sample rate, and extra bandwidth of the Rigol
would definitely be the tipping point for me if I was chosing. The extra
memory will serve you better in the long run.
Rigol are quite good, so good in fact that Agilent (HP) rebadge them.
Have not played with the Instek ones myself in-depth but have heard many
good reports (and no bad reports).
Warranty? It's nice, but I wouldn't let it sway my decision over the
features/usability. 3 years is good.
I'll throw another spanner in the works and also tell you to also consider
the "mixed signal" version of these scopes. They typically have a 16
channel logic analyser built in as well. Can be very handy for
microcontroller work, but it adds extra cost that you could put into say a
seperate PC based logic analyser.

Like all of them I have seen, there is no mention of a magnetic shield
being fitted to the CRT - this means the trace will wobble or shimmer
if ever you bring an AC supply transformer near the unit. Nearly ALL the
famous brand US or European brand scopes have magnetic ( ie Mu Metal )

Whether this matters to YOU depends on what sort of work you intend
doing and how you like to install the scope on your work bench.

Personally, I cannot bear to use a digital scope.
My 5MHz Heathkit scope has a mu-metal shield.
Or at least it has a shield of something that _looks_ like mu-metal.
Doesn't work for snot, though -- it wiggles all over in the presence of a
magnetic field. I think they just put something in there so it'd _look_
like it had a shield (either that, or there's something special about the
scope that makes it extra sensitive to mag fields, and it'd be tons worse
without the shield -- that's a scary thought).
