In that respect the platform is pretty outdated. The new Rigol HD scope -for example- has a Rockchip CPU which does have a GPU to accellerate graphics and thus can deliver faster drawing of screen objects. --- End quote --- What are you talking about? --- End quote --- What Tautech pointed to ofcourse... |

So basically Xilinx is telling you the same as I was writing: Zync is outdated. |

Unfortunately many Youtube reviews are rather shallow so I really recommend getting test units before committing to buy. I have regretted not doing that in the past; it ended up costing me several k euro because the equipment dealer didn't want to take it back while the unit clearly wasn't delivering what was promised. --- End quote --- :-\ :-\ :-\I don't think that they will loan a unit for a hobbyist............ --- Quote from: 2N3055 on November 03, 2022, 11:25:04 am ---AFAIK SDS6034 H10 Pro 350MHz is based on platform that goes up to 1 GHz, with 2 ADC and different memory architecture. Worldwide SDS6000A are all 2GHz platform, common with domestic 2GHz SDS6206H8/10/12 PRO, with 4 ADC converters. Only that platform has support for Jitter/eye. So if you want to "reach" 2GHz, and have jitter/eye option you either have to buy any world release SDS6000A (8bit), or full 2GHz chinese version. Software wise (except eye/jitter)everything else is the same, FFT length and all. --- End quote --- May be the new problem now is does the 10bit ADC is important......? I see many post talk about ENOB....and two tone FFT..... So the RTM 10Bit really greater(useful?) than SDS6000 8bit...? And any one can tell the SDS6000A UI speed? I am using RIGOL DS2102A.....very slow |O |O and it only 2ch that i look to buy a 4CH scope..... --- End quote --- Let me just chime in a few words about SDS6000A. It is a fast scope with large touch screen. It is also very nice to use. If you get SDS6000A you can upgrade it all the way to 2 GHz. It is 8bit but has low noise front end and noise wise will perfom on par with R&S. How important 10 bit resolution is? Well it is not so much difference, from 8 bit to 12 bit it is visible difference. It depends if you are doing stuff where you want to squeeze every little bit. In general work god 8 bit ADC and good front end does the job, and in Siglent SDS6000A both are world class. I have SDS6000H12 Pro, and use it daily and love it. Visual design of R&S scope might be a bit more designed for a aesthetically applesque type of appearance, but Siglent GUI is logical, modern and does the job. Scope supports lots of stuff not being mentioned often: mapping of network drives, excellent remote control over browser (both great for documentation), 2 custom probes presets per channel, arbitratry math in 4 math channels (you type a complex mathematical expression and that is the channel). It supports eye/jitter package (RTM3K does not), comprehensive power analysis package, excellent FRA (Bode plot) analysis. It has 2 zone triggers, many advanced trigger options, many measurements, track and trend plotting, histogram analisys and histicons that are always running histograms on all measurements (I love this one, it's fantastic)... It is a very advanced mid range scope worth every cent. It is also a part of growing family of new touchscreen Siglent scopes that are their strategic platform. That means active maintenance and development. I personally thing that RTM3000 (while very nice scope) is no match to SDS6000 in its versatility. New R&S MXO4 might be, I don't know, haven't try it yet. But I'm confused as to what exactly would you do with the scope? Is 2GHz really necessary? |

I told you SDS6000 has advanced architecture that uses no Zynq and has a separate application processor that has not only advanced ARM cores, but DSP slices, graphics accelerators and more... And it uses Kintex Ultrascale. OP asked if SDS6000A is slow. In course of answers you pointed out that Siglent architecture is slow and that new Rigol is faster, based on false info what is inside SDS6000 would be same as old SDS1000X-E .. So I responded. Naturally Rigol brand new 4000€ scope has faster processor that 450€ Siglent that is now 5 years old. But SDS6000 has very different, very fast architecture with ultra powerful Kintex FPGA and separate application processor. SDS6000 is very fast. |
