content: I want to buy an oscilloscope.. I do not mind if it is used. I do mind it to be in excellent condition. It should work properly. If the chassis has a minor scratch it is ok.some desired specs:-BW=200Mhz or more-2 channels , 4 are highly prefered.-1 Gs/sec for each channel, sampling rate should not drop when i use all channels at the same time.- good math capabilities (FFT,etc)required:-must work properly- comes with its power cable of course.other highly desired features:-all buttons and the other movable parts must be fully healthy.-screen should be spotless, no deffects.-external trigger []this is anedited line[]I do not set a desired price, i want to exlpore the potential options. I cannot afford to buy expensive stuff(e.g. 1000 euro product).In case of a deal you make it available on ebay for sale. []Edit[] i will keep an open window to other offers without ebay, although ebay makes me feel safer.

content: For this sort of enquiry it helps to know where in the world you live, either by setting the relevant information in your profile or stating it in the post.It also helps a lot if you do state your budget more precisely than "I don't want to spend €1000 ".As you have asked for 1 Gs/sec per channel you are looking at a fairly modern 'scope - the Siglent SDS1202CFL can be had new for significantly less than €1000 - probably half that figureOtherwise I think we need a bit more info about location, budget and what you wish to use the 'scope for.

content: And prepare to add 10-20% on the price if you want to get the seller to list it on eBay for you.I'm out. Sometimes a potential sale just seems like it's going to be trouble...Good luck, but like Grumpy says I think you might be better off buying a new scope.

content: Quote from: grumpydoc on January 09, 2015, 09:42:58 pmI am an electronics graduate, sadly jobless,i leave in Europe(Greece), i will reduce my food to buy one oscilloscope and practise what i studied before i forget everything even the basics... the ideal price would be around the 300euro. Of course,i think i cannot go beyond the 500euro without getting into trouble.... but i hate to say a specific price tag because i want to have an open window to other suggestions....I just need one... i want to be able to use an oscilloscope for low frequency practice and for some higher RF circuit home practice. The more BW the better for me to practice( 100mhz is not useless but it is simply very little)thank you.

content: Don't think that it is possible to get something decent for 300 EUR in Europe. As of options, probably buy Rigol DS2072/2072A and hack it to 200 or 300 Mhz, 2GSa/s will drop to 1GSa/s when using both channels. Likely will exceed 500 EUR even if bought used in Europe. Otherwise maybe some cheap Chinese stuff with lower BW version and hack later, some models were hackable IIRC. There are cheap Chinese oscilloscopes with 200 MHz bandwidth below 500 EUR for example SDS1202CNL+, and it have 1GSa/s on both channels. However it have low memory and seriously sucks compared to that Rigol.

content: DS1054Z is hackable to 100MHz AFAIK, here is tread about it on this forum. Overall very decent oscilloscope for it's price. But only 100 MHz possible.

content: I am thinking of Dave Jones' Review of Rigol DS1054Z episode 674. It looks good but a lot below the 200Mz :-(I would love to have a feedback from people who bought and work with a decent DSO.I am looking on ebay every now and then for new or used oscilloscopes, but i cannot make up my mind. I would appreciate some help/advices.I am particularly focusing on the following 'need to have' features:- 200Mhz or more BW ( if it's less, possibility of software 'upgrade' ....)-external trigger-2 channels,( 4 channels is the ideal)- minimum 1Gs/sec sampling rate foreachchannel ,when all channels are being used at the same time , otherwise it will be a poor product.- enough memory to work smoothly.I read one reply above which suggests the 70Mhz Rigol DS2072A( around 800 euros i suppose) with the possibility to 'upgrade' it at home.Price is an issue for me. Thus, i am trying to find the lowest possible price for the above mentioned features. What is it going to be my options?Thank you.

content: You will struggle to find 1Gsa/s/Ch specs in alow cost4 Ch DSO.If 2 Ch's are acceptable, the choice widens.For basic DSO use the Tek that you have been pointed to or the Siglent will do the job.Otherwise you will have to increase your budget.
