content: Edit 2: As expected it didn't happen. Ah well, I can get by without one.Hi.. just edited to note that I have been offered a nice deal of Old scope. Not seen it yet, hopefully within a week.. I hope it will be good enough.(old post follows)Looking inexpensive basic scope, normal desktop type. I know the pricing of normal Rigel,owon etc. At the moment woudl rather get something used.Equipment needed at Finland, so overseas delivery may be expensive.Joanna

content: I have 2) Agilent 54540A 4 Channel, 1 GS/s, 500 MHz Oscilloscope available for sale if you are interested. They were calibrated last year and have been sitting on my shelf ever since. I could offer one of these to you for $400 plus shipping and handling. There is some slight screen burn on this unit when powered off, but looks perfectly fine when powered on. This unit would come with a power cord, cd manual, pouch, and a 30 day warranty.

content: Sorry, even thoug that sounds nice, but can't afford those.I know i could perpaps get used digital ones around 200-220 Euros from Finland and that's most likely what i'd be looking for.

content: How set are you on getting a DSO?For around 200 euros,you may be better off getting an analog,as you would probably pick up a very capable Tektronix or HP unit for less than that.Remember that the early DSOs had less than startling performance,due to their very small memory depth.As always,I would suggest that you check to see if there are any Hamfests in your area,& have a prowl around.You may pick up something good!

content: Well.. It don't need to be DSO or even digital, but for some mysterious reasons basic analog scopes (like 20MHz/2ch) seem to be nearly nonexisting around here and what's available tend to cost more than these new china.dso:s.One alternative could be those tiny kit-like portable scopes, but I tend to doubt their usability when compated to real benchtop-machines.

What a shame!Have you tried asking one of the local universities? They have so much old crap in their shelves.

content: I have a Hitachi V665 - 60MHz, dual channel, delayed TB with readout cursors - nice 'scope for an analogue, smaller, lighter, more modern and better performance than the Tek 465's (though these are good 'scopes also) and I've run through all the calibrations so it's within specs on time base and amplitude.You can have it for €175 plus €45 shipping to FinlandI'll run a full performance/calibration report for you before sending it PM me if interested.

content: You should be able to get a Tek 2230 for that amount of money:http://www.ebay.com/itm/Tektronix-2230-Digital-Analog-Storage-Oscilloscope-100-MHz-2CH-10MS-s-/320913168734I sold mine a few years ago for €175. These are very nice scopes. The 4k acquisition memory is usefull for debugging I2C en SPI problems. The schematics can be downloaded for free and they are easy to diagnose & repair.

content: That particular auction probably isn't much use as it's "Ship to US only" - if the OP wanted a 2230 he might grab a bargain on the Italian ebay site, there's one currently at €14.50.http://www.ebay.co.uk/itm/Tektronix-2230-digital-storage-oscilloscope-/320912753644?pt=Attrezzature_e_strumentazione&hash=item4ab7e403ecI'm not so sure about "easy to diagnose and repair". Yes the service manual is easily available athttp://www.ko4bb.com/Manuals/Tektronix/Tektronix_-_2230/Tektronix_2230_Service_Manual.pdfbut the 2230 has quitew a few Tek specific ICs which are unavailable these days. Especially the CCDs which are prone to failure and critical to the digital section.The digital section is also pretty limited - 10 Ms/s per channel, not sure if you can combine that to one channel at 20Ms/s.

content: CCD's? The sampler in a Tek 2230 is a simple discrete diode sampler! I think you are referring to the Tek 2300/2400 series.BTW, most sellers from 'ship to US only' auctions are willing to send something overseas. Just ask. But I doubt the Italian seller will send it abroad since the description he wrote says 'italy only'.

content: Tek 2430A and 2440 have CCD.before I have sold many 2430A and some 2440.I have not meet any failed hybrids etc.But example after long time sometimes CCD need careful adjustment procedure (but also this rare).CCD is not used as picture sensor. It is used as analog fast memory before ADC. It was very advanced solution this time they have designed and manufactured. There was some advantages use these CCD's.2430 have 100MSa/s separately both channels and 2440 500MSa/s both channels.Excluding samplerate and memory these both are very well made equipments.But just as many 2400 models. If people do not know how to do service there is high posibility to damage these.(just becouse they do not study service manuabeforethey open it! )In worst case people take case open and shut power on. After short time he (maybe) have burned hybrids due to overheat. It is dsesigned so that airflow is ok if case is closed!)Building quality is super.Other weThese can easy find in eBay. (there read "as is" or not DOA. They are not DOA becouse there is some light when you turn it on)

content: QuoteMea culpa - yes, I think I was thinking of the 2430. There's still Tektronix custom stuff in it (the 2230, that is) e.g. the input channel multiplexor. However I suppose that's true to an extent for all 'scopes past the mid 80's designs to one extent or another. That said I don'tthinkthere's anything except generic parts in the Hitachi v-665 - mind you sourcing the quad-in-line micro-controller these days might be fun!QuoteIt never hurts to ask I suppose. However the Italian vendor has specifically marked his auction for international shipping - I don't speak Italian all that well but I'm pretty sure the "Italian purchases only" referred only to Italian postal orders as a means of payment.Edit: Had enother look at the auction - definitely has "Post To: N. and S. America, Europe, Asia, Australia", though postal rate calculator only offers Italy as the destination country. I see that i's now up to €129 though.Generally it will be much easier for the OP to import a scope of any kind from within the EU as there will be no VAT or import duty to pay on top of the ebay price - not only is shipping from the US frightening for something the size and weight of an oscilloscope but there will be VAT to pay on import which is 23% in Finland, plus possibly import duty as well (in the UK it would probably be under the threshold for import duty, don't know about Finland). That $260 'scope would end up at least €360.

The DAS9200 cost me $66 the shipping for the US to NL however was about $350. It came in a big box on a pallet.

content: Hi Joanna!Here's some scopeswith no shipping costs to EU.http://www.batronix.com/shop/oscilloscopes/Low-Cost-Oscilloscopes.htmlRigol DS1052E 269 eurosOwon PDS5022S 220.17 eurosLauriedit. They offer free shipping for the Rigol function gen(that Mike did a teardown) so I tought it was their policy on everything. The shipping costs for scopes are about 14 euros to Finland (DHL package deliverytime 4-5 days). It's german company. I think the prices are reasonable.

content: Warning though, the PDS5022S might seem cheap but it's only 25MHz and it's reliable as with the rest of the PDS series or so what i heard and the 100MSa makes you feel like you have been teleported into the 90'sAnd the STN display is shockingly poor

content: Quote from: l4rtt-1 on June 29, 2012, 10:17:20 amOwon PDS5022 have been extremely reliable but first it is 25MHz and 100MSa (both channels separately).It can do just it. samplerate is enough for 20-25MHz sinewave and thats it. For square waves it need think what risetime need, but thumb rules it is ok for 2-4MHz pulse shape waves.But it have battery option and it have been on the markets really really long time and falure rate is very low.It have been also maybe more "school class roiom" scope than hobbyists home scope?It is ok in its class. Also its FFT BW is nearly flat to 50MHz (in FFT selected) (useable for 0-50MHz)It is simple, it have tiny features. Still some real stores sell it with 400 euro price.It is totally silent, no fan.But now big warning!PDS5022S have DST display... who want look it in real life. It is really poor display today!There is NEW model what have TFT display and it is PDS5022T launched some time ago.Double price there here locally can buy totally different class of Owon with full servoce and customer care without risk.(also it is good to know that PDS do not really use display full resolution as SDS series do... )But of course grass is always more green in neighbourg or sometimes with specifications or prices or tests reliability peoples very easy compare jackfruit to potato.Just example this:QuoteHow these can be considered as alternatives for the same purpose or same skill level peoples.?Imho.. Owon PDS5022S(T) EDU is simple robust straightforward use for A-B-C level. If I am teacher and slect simple and robust extremely clear to use machines to middle school class room maybe I select this Owon model still over rigol. But for electronic hobbyist who are clearly over blinking led level Rigol (and Owon SDS and many many others give lot of more... if PDS5022Sprice is 220 then SDS7102 price need be thousand and Rigol some hundreds for balance.

content: Quote from: aghp on June 29, 2012, 02:24:55 pmSimple. The OP wants a cheap scope. If she wants the cheapest possible option she goes for Owon. If she wants a good scope that's cheap as hell she goes for Rigol.I just put the Owon there because it's the cheapest I could find. But for 50 euros more I think everyone would go for the Rigol.Lauri

content: Quote from: l4rtt-1 on June 29, 2012, 10:17:20 amNormal people have to pay VAT too. So it is 262 euros for the Owon and 320 for the Rigol plus shipping.
