content: Hello EveryoneI'm interested in a new Oscilloscope.I searched quite a time now and the Tektronix 2024 looks interesting.http://www.farnell.com/datasheets/83460.pdfDownside is the price for a new one, but then you have the warranty which looks nice to mehttp://www.tek.com/service/warranties/warranty-18A Feature which i think is great is the "Mixed Signal Design and Analysis"also it has 4 channels.i searched a bit and found this oneOwon MSO8202Thttp://www.bestoscilloscope.com/digital-oscilloscope/owon-mso8202t.htmlUpside it only cost roughly a 3rd of the TektronixIt also has a logic analyzeri found it interesting according to the Datasheet the Owon has a faster rise time than the Tektronix (?1.7ns and the Tektronix 2.1 ns )but has only 2 channels.So I'm not quite sure if the Owon would be a good investment.The Tektronix is sure a good investmentBut it's expensive.If you know of a product that would be compareable to them pleas let me knowlast but not least what i imagine for a new scope:-bandwith at least 200MHz-Logic Analyzer is nice to have but I'm sure it makes things much more expensive-fast rise time-budget 3000€ would be really painful but it's a one time investment so I think it would be worth it.Cheers.

content: I haven't seen any reviews on the Owon MSO range. Given the firmware issues in the SDS series and the mediocre PDS series, I would much rather by a Tek (or Agilent or Lecroy) scope sight unseen than Owon.

content: Quote from: alm on March 20, 2012, 05:57:09 pmSure the firmware has issues but it's a cheap alternative .Yeah sure i like agilent but the last time i checked , a DSOX2012A is more then 3 times what i have to pay for a SDS7102VThe MSOX2022A is like 4 times more for 8 fewer channels then the MSO8202T . So yes , Agilent is a big notch more expensive for the MSOX2022A , but it's good stuff , the SDS7102V is good for starting out , but eventually pretty sure you will buy a agilent DSOX3000 .( OOPS , agilent's MSO addon for the 3024A is like 1800$ )

content: I agree with the hameg 2024... I would choose this one with a logic adapter and some software (i2c spi ...)I would love to see a rigol alternative to a small logic analyzer but with software pattern recognition like i2c or spiI have a open logic sniffer, it's enought for my needs, but the user interface is pretty "crude" ...someone to make a decent lcd interface to clip on a logic sniffer ?my 2 cents...

content: The Tek MSO is a decent scope (different beast to the TDS ).But I'd consider the Agilent and Hameg MSO units as well.Mixed signal scopes are nice to have, and if you have the money, go for it, but I think that if you have to ask the question, you probably don't need it, and it may be better bang-per-buck to get a non MSO scope and a separate logic analyser. In this respect, the scope that you pay extra for the logic analyser kinda make sense. Buy the analyser only when/if you need it.The Agilent 3000X is probably just out of your price range.BTW, the rise time simply matches the bandwidth. So all 200MHz scopes should be effectively the same rise time.The Owon? Well, it's an Owon...3000€ is a lot of coin for a scope, so make it a good one.The Hameg HMO looks like a good deal at < EUR 2200200MHz, 4CH, mixed signal.http://www.distek.ro/en/Product/Digital-Oscilloscope-4-x-200-MHz-Hameg-HMO2024-1093https://www.buerklin.com/default.asp?kwd=Digital-memory-oscilloscopes-type-Hameg-HMO-2022HMO-2024&event=ShowDvNr(K101580)&l=eDave.

content: Thank You for the replies.Yesterday I had a look on the HMO2024.Looks also good, but i decided to go for the MSOX2024A costs about 400€ more but i think it may be worth it.i simply posted i wanted a fast rise time because i did see there are some differences in the rise time (OK only some ns)It's just wanted to go sure^^ (and yes it's my first buy of a Digital Scope)@ Dave after watching your blog about the Agilent one, it made me exited.I don't need an Analyzer right now, but there is a high possibility to need one for future projects. So i might get one right now.A big Thanks to allCheers

content: I have a Tek TDS684 with options 13/1F/2F and a Tek TDS784D with options 13/1F/HD/2M/2F/2C available if you are interested. The TDS684C is available for $3,300 USD and the TDS784D is available for $4000 USD. Both of these unit's have been calibrated with data, and come with a manual on cd, power cord, and a 30 day warranty. I can send you photo's if you are interested.

content: sorry to interrupt, but it seems that the agilent 2000 serie is not capable of interpreting logic serial busses like i2c or spieven with a costly option...and to me a logic analyzer without these features is useless, better buy an inexpensive logic sniffer...if you want a decent logic analyzer, you must go to the agilent 3000 series, which is quite 2x the price of the 2000 plus options...no definitely the hameg 2024 is very good ratio features/price range and has options to interpret serial signals...the other dont have the option or are much expensive.please correct me if I'm wrong !

content: Yeah, like most of them, the decoding for different comms are optional. If you're set on the Agilent 2000 series, you might well be better off with a DSO and a USB logic analyser, unless you're mostly working with parallel busses or willing to decoding in post processing. Review of the HMO2024 if you're interested, with serial decoding on the analog channels,

content: Thanks for the Video.I might really go for only the Scope without the logic analyzer.But for the price of the agilent I can get the HAMEG without the Serial Bus feature, but it would have the logic analyzer.Hmm it seems I must really give it more thought -.-

content: Quote from: Write_to_Smokegenerator on March 21, 2012, 08:12:08 pmYou get 25 times more wfrm updates per second ... invaluable .The smaller memory depth is due to the faster update rate , really , buy the Agilent , the quick wfrm update will pay off for itself .Now , if you want a logic analyzer ... Get a separate logic analyzer .Or the logic sniffer from seeedstudio which can support up to 32 channels , 32 CHANNELS ?!

content: It depends what you're planning to do. If you're working with analog electronics, then you probably won't need the digital channels. As most people end up playing with embedded systems at some point though, the digital channels become pretty useful.The digital channels on the MSO scopes are typically higher performance sampling than the standalone sniffers. This can be essential if you start working with high speed digital, FPGAs etc. Having said that, for playing with general embedded stuff, you aren't likely to need that. And the standalone units generally have excellent software, which can decode lots of protocols for no more money, as opposed to the upgrade approach on mixed signal scopes.As well as being higher speed, capturing the signal on a scope also has the advantage that the signals will be correlated in time with your analog signals, which can be extremely useful for mixed signal systems.As for waveforms per second, it's nice, but I wouldn't get hung up on it as the deciding factor, whereas factors like memory depth is absolutely critical for long single shot captures, the need for which comes up extremely frequently

content: Quote from: DaveW on March 22, 2012, 01:36:32 pmReally important is the update rate , easy to catch glitches .Memory depth , if you want that over update rate the hantek is fine .but if you memory depth and update rate , hoho , X3000 .But mind you the open logic sniffer has a sampling rate of 200Msps on across all 16 channels .And 100 Msps across 32 channels .Now how about 8 channels , yep , 400Msps . I think .
