content: Wow, up until now I thought an Agilent-Like scope from China was called a Rigol!Now it looks like Agilent has created another Rigol. Damn American companies need to stop being greedy and start making their products in their own country so they quit making new companies coping their products.

content: heyfirst - I want to vomitsecond - in my opinion rigol is not chinese , rigol is the US presentersin china( Kiethely yokogowa and Yamaha are good chinese companies which in my opinion are high end and some good value per $$ )rigol is some good company - they are good competitors and high value in my opinionunlike the others "chinese" stuff witch I call garbage !take a look at the iphone 4S fake and stuff like that , they cost nothing , and also worth nothing ,BTW - to make it clear , I am galaxy guy

content: Quote from: eevblogfan on May 17, 2013, 08:26:32 pmI think both Chinese and Japanese companies wouldn't really like you mixing them up together (Yokogawa & Yamaha = Japanese / Keithley = American)QuoteYes, thinking of them at this point as an Agilent-imitator is pretty ridiculous. The DS2000 and DSOX2000 are only alike in the bandwidths offered and the relatively similar maximum update rates. In virtually every other way they are significantly different.

content: yup sorry for mixing them up , stupide ADDanyhow , the rigol 2000 series and agilent's 2000 series are the same price range , BW , and many other things , aside of that the rigol gives you some advanced stuff , like that neat rotary encoder for scrolling the recorded waves

But can not find any review or video.And logic analyzer specifications?More info:Hangzhou Weibo Technology Co., Ltd(Hangzhou Jingce Electronic Co., Ltd. ) is a manufacturer established in 1999, specialized in research, development, design, manufacture, sales, installation and service of integrated professional Automatic Doors, digital storage oscilloscope, function generator, LCR meter, DC power supply etc.Our new factory building area 35, 000 square meter is under construction will finished in August 2013.

content: Quote from: Hydrawerk on May 18, 2013, 06:55:35 pmAn FPGA to emulate a complex ASIC would likely be a very expensive one (not counting development cost) - an ASIC uses silicon area efficiently, but because FPGAs are general-purpose, there will always be some unused silicon area which you are still paying for.If it was possible to get the functionality with a cheap FPGA, why would they have spent a fortune developing an ASIC?

content: Quote from: Fsck on May 19, 2013, 09:44:19 amI am actually surprised we haven't seen many cheap rubbish touchscreen-only (no knobs) instruments until now. There are these nano DSOs, but that's about it. Smart phones and tablets made touchscreens a cheap consumer technology. Stuff like thishttp://www.ebay.com/itm/360500650084(1080P 4GB 4.3" touchscreen video player) can be had for for $30. But for some reason the technology doesn't appeal to the cost-obsessed junk instrument manufacturers.

One reason for that is that they don't have knobs.But the point was that junk instrument manufacturers are cost-saving crazy, and don't care much about ergonomics. So it is a bit surprising that there is no wave of touchscreen-only instruments from these manufacturers.QuoteYes, I know, e.g. from R&S. But they have "everything", touchscreen, traditional knobs and allow to connect a keyboard and mouse.

content: They probably don't like to innovate all that much... "since the western scopes (Agilent, Tek, LeCroy, etc.) all have knobs, ours should too".Although pinch-to-zoom to adjust the timebase and V/div scales might not be all that bad for the iPad-using crowd... no, I'd still want knobs for everything else.

content: One may consider that e.g. for Android tablets, designers are looking at housing a generally generic PC that can run the OS, so most R&D is in ergonomics, size and power reduction; they can easily contract subsystems for bluetooth, wifi, USB etc.,. already used by other makers that in economies of scale, can make them affordable to include. But in T&M, a good fraction of a design budget is in fundamental measuring capabilities, say as a DSO, plus regulatory approvals are far more taxing to pass if not more numerous. Add to it, the T&M market is smaller, the device service life longer, and the actual experienced device designers for that type of gear, much less numerous.

You know, make some more money from people thinking they get a real 1080p player. It says it "supports 1080p". I guess they forgot to add it also "supports 4k UHD". Now it may choke on that bitrate, but hey it supports it. Still, $30 for a random 720p player isn't bad...
