They have only one left, looks like it'll be discontinued. But at 200
Euros you almost can't go wrong if a simple low bandwidth analog scope
is
enough. Ships from the UK and says "Código classificaçăo fiscal:
90302010", not sure if there are still import tariffs within the EU.
I've noted just now: the price is exclusive of VAT :-( Them, to
Portugal is
200+21% of VAT, thats's aprox. 242 EUR.
That's a high VAT you guys have to pay. I just tried and it said:

Subtotal: 200,60 EURO
Portes: A confirmar
IVA: 0,00 EURO
Total: 200,60 EURO

Didn't go any further because I don't want to buy it. Probably they
calculate VAT after entering the address. I thought they had to show the
prices including VAT, at least that used to be the law when I lived in
Germany.

Anyhow, I don't know if you can buy a new scope for less than that
anywhere.

Looks like you can:

First hit on Froogle.de

Wow, indeed, says it even includes tax. I've never heard of the brand
Sako though.

Me neither. I guess you just take your chances with all these no-
namers.

Dave.

I just think you'd better buy a known brand used scope for that price...
just my opinion...

For more experienced users, definitely, but for a beginner it's not an
easy decision.
A new scope will be 100% guaranteed working and in spec, and has a
year or more warranty on it if something goes wrong.
Second hand scopes on the other hand are a lucky-dip, you just don't
really know what you are going to get. A "Tested and working" Ebay
unit isn't always as claimed. You can get ones that have been
professionally tested and calibrated, but they cost a lot more.

Dave.

Then there are places for used stuff where they give you a little more
security with used stuff. Such as Singer oder Flugversand Buescher in
Germany. Of course, there you also pay more.

Hello!

I wish to buy my first oscilloscope (for hobbyist). I have search some
information in the Internet, but I still have some doubts:

-I live away of the large towns and I have to buy it from an internet store,
from inside the European Union (to avoid import taxes). I have this one in
mind:

From german storewww.conrad.com, a VoltCraft 30 MHz oscilloscope 630

"Professional two-channel oscilloscope for service, laboratory, training and
DIY use. Outstanding in its class due to its reliability, technical
equipment and price. Clear, conveniently laid out operating elements. Even
the smallest signals can easily be read off on the 8 x 10 cm rectangular
screen. The max. vertical deflection of 1mV/cm means that even small signals
can be measured. The highly sensitive alternating triggering guarantees a
static screen image for both channels, even at different frequencies. The
TV-V and TV-H operating modes allow triggering of video signals. The XY mode
is useful for the 4 quadrant characteristic curve. A 50 W output (channel I)
is available for the connection of frequency meters."

- 30Mhz are ok for a hobbyist?

-Does the scope include any probes or I have to buy it apart. Cheap chinese
probes from Ebay are ok?

-Any additional avise?

Thanks

Personally, I'd go for a Rigol, to be more specific a Rigol DS1042CD or a
DS1062CD
http://www.rigolna.com

They are in fact rebranded to be "agilent", I believe they are the agilent
6000 series without the price tag and more standard options

Here in Germany it shows 292 Euro. Is there a discount for the USA? ;-)
For that money you can get a used scope with 3 times more bandwidth and
lot's of fancy trigger options.

The price at the bottom of the page is the price for an "alternative
product"


Yes, the GOS-620 price would be to the right of the last scope on this page:
http://pt.farnell.com/jsp/search/browse.jsp?N=4364+500005+1002079

Euro 200,60. I am quite happy with Instek, got their flagship scope
GDS-2204. The knobs and buttons somehow feel more robust than on similar
Tektronix scopes and so far the performance is great. But this is a fast
digital scope, very different ballgame. I don't know their analog scopes.

Doggone, that is pretty nice for under US$2000.
