content: Is the power supply the same as the other Rigol instruments of this generation?Looks like Rigol have moved from AD Blackfin to Freescale i.MX. Interesting choice.And one quad ADC chip instead of two dual ADCs, rare to see that in a 4ch scope, this is a budget model though.

content: I have to admit, that's a pretty crusty looking scopeThey should have added 4-channels to the DS2000-series. This business of making different models for every possible configuration instead of just choosing a single useful configuration for each price range is annoying. Soon, Rigol will have 200 active products on the go if they keep this up

content: Quote from: olsenn on August 14, 2013, 04:00:05 pmYep, on the DS4000 you can move from 2 ch to 4 ch for $400 at 100MHz and from 2 ch to 4 ch at 200MHz for $300. Rigol should offer the DS2000 series with 4 channel increments at same type of pricing increments rather than forcing you upstream to the DS4000 series with more Mpts and wfm/s than some users need/want, or downstream to the DS1000 series.Seems like test equipment product managers sometimes spend more time thinking about playing chess with the competition than satisfying the customers. Kind of like a restaurant that says you can only have this bun with that burger and these dressings, and no substitutions – might be easier on the kitchen and in theory more profitable for the time being, but longer term – maybe not so much.You don't need every option at every price point and infinite flexibility (although with decreasing hardware costs and software invoked features we're headed in that direction), but you need a gracefully incremental growth path that anticipates what the market wants. The winner will be the company that can best anticipate and execute.Overall, Rigol is doing a fine job but there is room for improvement, and the same with Agilent (especially with their approach to serial decoders and LA functionality limitations on the 2000) – just thresholds and walls that frustrate or annoy customers.It's like it's all sitting there for the first one of these two to see who really figures it out, Rigol or Agilent. The longer each waits the more they lose some customers to the other (that's the nature of competition no doubt), but I think at the low low end (around $500 and under) and at the high low end (around $1k) and at the low middle (around $1500-$2k) Rigol is very likely taking share from Agilent.So, while Rigol could improve a few things I think doing so might maybe enable them to run the table on Agilent in the lower realm of the market. For Agilent they either have to abandon the lower realm or step up. Agilent probably doesn't care about the lower realm as they are happy to live with the pro "commercial", "industrial", and "enterprise” markets. Agilent's challenge might be that once Rigol firmly embeds itself at the lower realm Rigol will only getter hungrier to move upstream.I think there is still a ton of opportunity to figure out how to better leverage the integration of traditional "electronics" and "digital" technology - both in terms of managing users’ digital signals (serial decoding, LAs, etc.) and in terms of how to use digital technology to better monitor, analyze, and manage with test equipment (such as what Rigol is doing with the control and programming features they are bringing to $400 power supplies vs. what you currently get from Agilent for 2x the price).Without a doubt equipment operating precision and reliability and service and support are huge - especially in the pro markets but it will be a race to see if Rigol can figure this stuff out before Agilent figures out how to embrace the use of digital technology in way that brings more feature richness and better price performance. Clearly, more competition is good for users (by the way, anyone hear anything new from Tektronix lately? Sure would be nice if they came back to play at the level they once displayed.) Just sayin'

content: Tek has been REALLY disappointing in the low end lately. Their TDS and TBS series almost have laughable memories. 2.5k points? Are you kidding me? Their DPO2000 series aren't especially compelling either, and they refuse to lower their prices. A better price for Tek's 25MHz TBS1000 would be around $100, looking at the other products that the Chinese are making. Why must I pay over 1000 dollars for a DPO class scope, when I can go buy a perfectly good, 4 channel, Rigol DS1074Z for $600, and add on a whole bunch of goodies, like serial decode/triggering, waveform gen, etc. I miss the days when their 2247's and 2467's were trailblazing. And remember the TDS210/220? Those scopes practically invented the DSO market. Tek just isn't what it used to be. *sigh*

But who knows, Rigol had already chance to make it better on other models and they didn't.but they didn't ^^Quote from: crt on August 14, 2013, 03:07:53 pmOn the other PCB side there must be NAND i think, the Freescale i.MX is ARM9 based so maybe even Linux running.There is JTAG connector, if you can made a dump of the NAND.Quote from: crt on August 14, 2013, 03:07:53 pmthe first one can be easily identified over JTAG, the second one (the 4ch ADC) is HMCAD1511 from Hittite.

I have the 70MHz model and:Rigol 350MHz Probes (RP1300) - I mostly get 1.7ns rise time, but have seen a 1.6ns.Rigol 150MHz Probes (RP2200) - I mostly get 1.9ns to 2.0ns rise time, but have seen a 1.8ns.I am not using a decent rise time pulse generator - just a tactile button with some capacitors that switches from ground to +5V.Shouldn't this rise time be MUCH slower for this model as in 5ns?Is it possible the 1104Z and 1074Z are the SAME unit just with a different sticker on them?

content: Quote from: HarleyYan on August 31, 2013, 06:34:04 amI received my DS1074Z-S today, with the firmware version 00.02.00.SP1I have emailed Rigol about firmware update since this one has some bugs. Where am I suppose to request firmware by the way? (I just emailed their European sales office, it was the only email I could find)- I can not enter the advanced system info menu either with this firmware.- I can't save waveforms or CSV with large number of points, limited to very small memory, gives error otherwise.- If I turn the scope off with the signal generator turned on, it will boot up with it turned on as well (remembers settings), but the status LED will not be on (signal is enabled but no indication that it is on).- All advanced math functions (integrate, abs, sqrt etc.) only work when 2 channels are enabled (even though they should only need one channels), seems that you need to have specific combination of channels enabled: Ch1, Ch3 or Ch2, Ch4. Other combinations of active channels results in error message.- In menu: Utility -> System, there is option "VerticalExp", with no explanation in the manual or in the help menu in the device. Can be set to "Ground" or "Center", which determines the reference when you zoom in on a vertically offset signal. Ground is standard, Center means that the entire trace shifts vertical position when you change vertical gain.This was a few things I found during the first 2 hours of testing.

content: Quote from: alank2 on November 26, 2013, 10:07:48 pmSorry, I don't think this conclusion is valid. The BW = 0.34/tris only valid if the scope has a gaussian response. For example the DS1102E doesn't. SeeJump to 15:20. Measured 2ns rise time which would be 170MHz. But the real bandwidth is 136MHz.I made tests with a 74AC14 based oscillator into a 50ohm coax and a feed-through terminator. This is from my 100MHz DS1052E. The ringing is symmetrically around the top. My 100MHz analog scopes shows the same.This is from my DS1074Z. The existing overshoot is reduced. It's slower.Here with a RP2200 probe connected at the feed-trough terminator. First with the ground lead. Second with a BNC to probe adapter. The probe overshoots and therefore the measured rise time is lower.Measuring the bandwidth by rise time may not work and measuring the rise time with a probe may not work too.Edit:I doubt that it's possible to measure <2ns time times with only 1GSa/s correctly. What you see is the result of interpolation.

Even if you take 350/1.7=205.9 and then multiply it by 80% (like the error in the DS1052) you still get 164.7MHz. Far exceeds what I would have expected.

I could only save the screen image, even slower than connecting a thumb drive to the scope, and pressing the hardcopy button... The CD found in the scope's box contained only the manual, and an almost useless frontend that only can be used to send some commands which aren't described well.Is there any possibility to remote control this scope from a PC?
