content: I search a new AWG with 2 channels, the maximum frequency is not determinant factor for me, I repair power electronics, test of automotive sensors and I do some things with arduino or pic. I see specifications of two equipments, Rigol DG1022Z and Siglentsdg1032x, just similar, The Rigol is probable more powerful, but Siglent display is better. The specifications are a thing but, the on field performance is the final veredict, anyone have experience with these devices?

content: Actually if you need square waves and pulses SDG1032X has much better performance..Rigol has longer AWG memory.. They are both worth the money, but each has edge in some functions..For general use as siggen, I would go with SDG1032X because of dedicated pulse generation and faster edges..

content: ok thanks for your help, on arbitrary waveform is very important the memory? I have a Agilent dsox2002a with 1M of memory, for example if I get the waveform from oscilloscope on csv format, I can generate this waveform with in every AWG right? For example in the rigol can hack and get even more memory, on siglent with hack can extend memory? it has just same memory than my 33120a, I think for waveforms created on software the memory is not important, but for direct capture from oscilloscope, the memory is very important I´m wrong?

Besides the memory length the method of loading the CSV file into the waveform memory is just as important. The most convenient way is being able to read the CSV file directly on the AWG itself without needing a PC. I did some testing with a Tektronix AFG31000 series generator (which is in an entirely different price class) and it can read CSV files from oscilloscopes by itself which is very convenient. Several years ago I tried to do the same on a Siglent SDG1000 series generator but that was a major PITA due to the crappy PC software. Basically the whole operation came down to changing a bit of the header in the CSV file so the generator could read it; it wouldn't have been hard for the generator to read the CSV file directly.

content: sdg 1000x can get directly from csv without modify? I read on manual, says can get csv from USB stick, but even change a little the header I think is not big problem, the problem is the numer of data I can get from oscilloscope. Also I want get a old TDS3012B, this scopes only has 10k of memory, but, if siglent only can drive up to 16k, only old tektronix data would valid for it? or it can comprime data and only get 16k from agilent capture?

content: If hacking is an option for you, I would go with Rigol's DG811. Currently best bang-for-the-buck "professional" entry-level AWG. Convert to DG992 level and be happy...P.S. Looks awkward but performs well.

content: Quote from: TurboTom on February 06, 2021, 08:49:32 amExcept with pulses. Specially when go to long periods with short fast edge pulses even SDG1032X beats it hands down. Just like on off.. other can, other can not. So all have pros and cons.Take out 100ns wide pulse with 10ns rise and fall time. Set period to 1s. So simple thing and just total game over. After then you change period to 2s ... oh well... it do not tell anything and is just write over your last pulse width what was in 1 second case 10us. And after you change only period, then pulse width is 20us. Then you change period to 100s. What a ... it have changed pulse width to 1ms and now it have also changed pulse rise and fall times to more slow. Even with 20ms pulse period minimum width is limited to 200ns... I tried emulate one very low energy very low speed information transfer and ... with this generator it fails totally. It was surprise that Rigol need even these modern models keep pulse width and period time coupled together. I do not at all understand why. Generator need wait even one day and then generate 50ns pulse without any extra than enter these parameters, period and width and rise and fall time.This is why Siglent have bit different pulse engine... only its name is real fun... "Easy Pulse"... I do not know where they have found this Easy to this... what is Easy... its one function is generateperiod independent pulse lengthand rise and fall time what is also adjustable.But overall if look DS811 mod 922 features and price - amazing instrument wiyh full of features and quite good performance and totally different building quality than some FeelE total crap shit toys. I have 2 of these FE/FY6900 toys here. I have not many times seen this kind of shit junk, even all connectors are most crap ones what can found in junk markets. Also it do not meet any single electric safety standards-rules, also not China domestic ones.And DS811 is not far more in price. When it is mod to 922 it is, still with its some cons, good value for money in this class, there is so many pros over these cons. Except if need things what it can not, like these pulses what I told. Building quality is good+. Outlook is weird. Also it do not have fan.

content: I’ve used the SDG1032X, the DG822 and the DS1022Z and I’d probably go with the DG811 and crack it which is fairly easy. Note that the frequency counter on all of them is dire and useless so don’t buy it for that. SDG1032X is fairly nice though but the bang/buck is off.rf-loop mentions pulse issues which you can work around by triggering the second channel off the first on the rigol by connecting a BNC cable upNo fan is a win for me! Someone has made a 3DP cup holder for the DG8xx as well if the odd design is too much for your lab

content: Quote from: bd139 on February 06, 2021, 01:17:31 pmAnd there after then two independent channels for generate these pulses? So how easy it is - one cable? If I tell problem do you thing that I do not know what I am talking.I need one 1000ns pulse and emulate situation there is other much more short pulse and important is its timing related to this other pulse. In real system it make "window" (measured when long pulse is high) Second, short pulse position inside this 1000ns "window" is this important thing and it need simulate with generator in preliminary testing phase. And it need work even if pulse interval is 10ms or 10000s or what ever and it need be repeatedly adjust for test different cases.Bit same kind of thing, I remember one generator (Not Rigol) what was advertised it have two independent channels and then it have also modulations.... oh well... when use modulation it was 1 channel generator... because it need other channel for generate modulating frequency... so, many kind of toys.

content: Well the problem is you end up having one usable pulse generator out of two channels off these cheap arbs. One BNC cable. First channel generates the trigger pulse, second channel is triggered by that and generates the output pulse. As for the window that can be pulled off the sync output for the first pulse.I’m not sure exactly what you’re after there TBH but you can get pretty creative with these after a couple of cans of red bull or cups of coffee

content: There isn't any difficulty generating short, fast pulses with a single channel of the DG800/900 series: Configure the pulse you like at an arbitrary frequency, and then use the "N Pulse Burst" function with the pulse count set to 1 to adjust the repetition frequency. My example shows a pulse of 16ns width, rise-and fall times of ~8ns (limit for this AWG series) and a frequency of 1 Hz. The other channel is still available and no external wiring etc. required. Sorry for the shitty quality of the photo...

content: Of course I know what it can do. So trivial basics.But...When I need2independent short pulses, as I told, with independent but sometimes long period or very long period and so that both pulses width can adjust independently and with small ns class steps and so that I can fine adjust other channel pulse position relative to other channel I really do not change my needs to match generator. In this case I change generator so that it match to my needs. Not vice versa because I am not playing just fun for spending time.

content: Don't know about the Rigol, but you have a Siglent DSO. If you want to do Bode plots the Siglent DSO supports it's own AWG I believe. Another is check out the 2 Tone IMD test, and note that if the DSO was perfect from an IMD standpoint, then this implies the AWG is at least as good as shown which is pretty good and likely even better than shown due to the DSO IMD!https://www.eevblog.com/forum/testgear/two-tone-test-with-scope-and-sa/msg4232071/?topicseen#msg4232071Best,

content: Bode plot is neat but unnecessary. You only need to work out phase flips and 3dB / 6dB points mostly and you can do that sweeping by hand effectively. Actually takes less time than setting up a bode plot and you only need a 2 chan scope for it. NanoVNA is better past 5Mhz

content: Quote from: bd139 on June 12, 2022, 05:44:10 amOperating word, mostly, that is if you only doing if for the stability reasons as a quick check... Than you can do it by hand. Agree.If you want to get gain/phase response diagram doing it by hand is not really fun..Especially if you're tweaking something that has multiple poles in response. And repeating measurements...VNAs are usually only for 50Ω systems.Truth is it really depends what you do. I use FRA (Frequency Response Analyser, that creates gain/phase plot) more than VNA.The idea is that FRA is for non 50Ω systems and less than 10MHz systems...Does somebody need that, it is up to them, defined by what they do...DG811 can be "unlocked" to DG992 but amplitude won't be calibrated above certain frequencies..One thing that is great about my SDG6000X is that has VERY accurate level in full frequency range (even those "liberated", they calibrate them all full range, despite destination model speed). One thing to have in mind.

Example this.(and full dynamic range is not used even close)Or just this very simple where -3dB bw is what it is but -60dBc points are very important (but my example is poor for this). Of course for these things are better tools but, also today these modern osccilloscopes give more and more...(I do not have my old Rocwell-Collis filters or Racal filters BodePlots (made with other instruments) available (all gone when bunch of hard disks accidentally damaged time ago. These oscilloscopes can not go to -120dBc when ref level is 0dBm. But, for many hobby grade things with these scopes can do lot. Lot of more than these old simple methods can even dream)Or just simple 3 channel FRAAgain much more is is interesting than just -3dB points.In all cases just SDG1032X used for test signal.

content: Personally we would never consider a modern DSO or AWG that's not directly compatible for Bode Plot capability.Folks that downplay Bode Plots usefulness haven't spent the time with this built-in feature, and I count myself in that category a couple years ago!!Before we acquired a SDS2102X+ (later a 2104X+) a FRA was employed for Bode Plots if available, usually not, or just the old hat input sweep, scope record, and then plot results which required having to convert in dB and getting the phase....real PITA!! Even recall using a Tek scope as a high Z input preamplifier as an input to a 50 ohm HP NA as a make shift FRA. Lots of work and such which now can be accomplished in just the DSO and no additional efforts other than a few setup parameters, and produces decent Dynamic Range (with input scaling) with nice graphics (will be interesting to see how well the new SDS2000X HD performs in Bode Mode)!! And for icing on the cake with a couple $ spent on an DIY Isolation Transformer, one can even do very respectable Closed Loop measurements!!From an old retired analog guy I must say that these modern modest priced DSOs are amazing, not only doing anything and everything the old analog scopes could do, and generally even better, and incorporating a Logic Analyzer, very useful FFT feature, Bode Plots, waveform stats, remote access and on and onSo why would one consider an AWG that's not compatible with the DSO, is there a big price difference, or feature difference, or performance difference that's compelling enough to forgo the DSO compatibility?Best,

This is quite useful and why now we wouldn't consider a DSO, nor AWG compatibility, without this built-in capability. Of course YMMVBest,

And new was very expensive.Making a statement that a very expensive specialized instrument is better at something than a inexpensive FRA equipped scope is kinda obvious.. It should better be better...The thesis here is going the other direction: FRA is good enough for most uses that you don't need to buy expensive specialized instrument for many tasks...I would personally like to own a Bode100.. I just can't justify the investment..And FRAforPico and Siglent's FRA running on 12 bit scope and even FRA on 8bit Keysight does a great job in general...But lately it is mostly SDS6000/2000HD because it works great. I use external SDG6000/7000 generator if I need more signal, or 2000HD for all in one... Although integration with external AWG is seamless and just works...Keysight implementation on 3000T is very easy to use and also very good. But Siglent's implementation is more sophisticated and 12 bit and bigger screen wins.....
