content: At the first glance the basic specs read quite good: bandwidths of 40/80/100MHz, 2 channels, 1.2GSa/s sampling rate, 16bit resolution. 8M per channel isn't really that great at 1.2GSa/s, though, and when considering that fast memory is dirt cheap they should have included at least 16M per channel (actually 32M or 64M would have been more appropriate).And again USB and optional GPIB (via USB-to-GPIB) adapter are the only conectivity options, there's still no LAN. Really, Siglent?And it looks like their waveform editor (EasyWave) is the same crap as for their other AWGs.At the end of the day it's an SDG5000 with higher sample rate and larger sample memory, but still Siglent hasn't addressed some of the primary issues with all their AWGs which is connectivity (LAN is pretty much standard in AWGs these days aside from the entry level class) and the truly awful EasyWave software.Plus, I'd expect a truck load of firmware bugs when this thing comes out, as it has been typical for Siglent.

Because LAN is surprisingly absent from the (admittedly Google translated, as I don't speak Chinese) website and pdf spec sheet.And since you seem to know more about this device: even if LAN was listed, are we talking about a LAN port that's actually built-in this time, or again a promise of some "LAN option" that very likely will not materialize (as it happened with the SDG1000 and SDG5000)?QuoteOpinions can hardly be 'disinformative', hence they are called 'opinions'.

content: Well, if this new AWG really does come with LAN then that would step forward (even though I'd wait until we actually see units in the wild, as Siglent has promised LAN before and then silently removed it).And it still leaves the poor software and the somewhat small 8M sample memory, though.

content: From what I can see on the Chinese web page, it has a touch screen, and the cost is between approx $675.00 and $1000.00 USD, depending on model. I wish they would give some serious attention to Easywave as well. I find it frustrating to the point of uselessness.

content: Maybe it is better to use an audio file editor and import that into the AWG. There are also software packages which specialise in creating waveforms for an AWG. IMHO there is not much reason to come up with a super-duper waveform edition because there are already other (commercial) packages out there which do a much better job than 'software which comes with an AWG' can ever do.Regarding the LAN interface. The biggest question is if it works. My Siglent SDS2000 also has a LAN interface but it is not functional beyond pinging and sending *IDN.

content: EasyWave is poor, it is true. If people have good math head he, of course, can write math equation of waveform using EasyWave math equation draw and get what he want. Example something like this: 10*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(1.6*(sin(10*x))))))))))))))))))))))))Hand drawing - editing is totally painful just if want go over kids fun play level to level what professional need in his works. Some times it is more easy to write waveform using notepad (queye of time, value pairs) and then transfer this text file to SDG.I do not know good(!) universal software for arbitrary waveforms what give out normal csv.If there is some good third party software, then do not need touch EasyWave at all.Waveform data need be like this (+ standard siglent header)SDG can of course read this kind of file from USB stick also. Time (xpos) is not always nessessary, it can also be just row number instead of time. (for 16k arb memory just 0 - 16383)<here header>xpos,value0.000000e+000,0.000006.103516e-008,0.038351.220703e-007,0.076701.831055e-007,0.115052.441406e-007,0.153393.051758e-007,0.191743.662109e-007,0.230084.272461e-007,0.268414.882813e-007,0.30675...etc until memory end

content: Agreed ... touch screen adds no real value but adds to the cost.Sample memory, sample rates and window functions . I guess this should be obvious but I am not sure how these relate to a signal source. To me they are terms I would associate with a scope or Spectrum Analyser. Back to the books.When the term "converter" is used can I assume this refers to the DAC.I have a scope that becomes annoyingly unresponsive in different modes. I thought it was operator error. Comforting to discover it is poor design.

content: Happy Friday.I thought this update to the SDG2000X FW might interest some of you. #1 was from a customer request. They are doing some very complex signal generation with sweeping, phase offsets, etc.1. Added phase deviation option in channel tracking mode2. Optimized the User Interface, including save/recall, arb, etc.3. Supported long pressing the Output key to switch the load between 50ohm and HiZ4. Supported to autosave the imported binary file (*.bin).5. Fixed some bugs?a) Unexpected change on Phase difference between channels in sweep mode when switching the style between linear and logb) Channels not aligned when the frequency of one channel is integral multiple of anotherc) Wrong sweep profile when using manual triggerd) Unexpected reset on output when setting illegal parameterse) Unstable waveform at the beginning of after enabling the outputf) Display error when switching between TrueArb and DDS in Arb modeg) Frequency deviation display problem in Counter modeh) Wrong project name in system informationi) When pressing the waveform button, the parameter button flashesj) Unable to set variable load value without touch screenk) Unexpected digit jumping when setting parameters with the knobi) Set CH2 to invert and then do a system -> default, the option will return to “normal”, but the signal will stay inverted.http://www.siglentamerica.com/USA_website_2014/Firmware&Software/firmware/SDG2000XUpdate-16R2.rar

Siglent doesn't build the 33500B Series (or anything else I'm aware of for Keysight, wo has some relationship with Rigol for bottom-of-the-barrel stuff).I had the chance to play with a SDG2024X for a bit, and the difference in the overall feel of quality between the Siglent SDG and my 33522B is like day and night. And in hindsight, I'm glad I went with the Keysight.

When you consider the $3000 price difference between it and the Keysight,I am happy to deal with a few quirks and adjust accordingly.The specs aren't that different .. indeed, one could make a strong case for the Siglent.W7NGA

I however was just fed up with the quirks, and even more so with the crap software Siglent (and Rigol) provides for their AWGs.I also paid a lot less than $3k for my (like new) Agilent 33522B (which came with almost all options) and including a 3yrs repair agreement (i.e. like a warranty). Plus three or so years down the line chances are good that it will still be worth a considerable amount of money.

content: Quote from: Wuerstchenhund on January 18, 2016, 06:48:05 pmDunno what you pay for it but it does not matter, the normal street price for a new Agilent 33522B is well over 3000 USD, SIX times the SDG2042X ... LULZ !PC software apart there is no way to justify such difference, especially looking on specs.The truth is that if it was not for active chinese brand like Rigol and Siglent we'll still be here paying something like 3000 USD for a crappy Tek / Agilent 40Mhz 20kpt scope or 5 Mhz 200Ms/s arb. generators.The game of easy profit in this sector is over, no more shameful multiplicative cost factor for china made equipment.For the cost of your Agilent 33522B a hobbyist / prosumer / small factory can buy a full lab test equipment set, including 4 channel MSO, arb. generator, spectrum analyzer, desktop power supply, DMM, soldering station, always thank to Rigol & Siglent.In contrast a big brand lab will consider your Agilent 33522B a backup instrument, at best.I sit in front of a brand new SDG2042X, works like a charm a for the price is a steal, no matter what.Many thanks Siglent !

content: Quote from: markone on January 19, 2016, 01:43:43 pmIt somewhat does, because the real price is a large part of the value proposition.QuoteTrue, but then on ebay they sell closer to $2k:http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=33522B&LH_Complete=1&LH_Sold=1&rt=nc&_trksid=p2045573.m1684Most of them also come with some/many/all of the options.QuoteIt certainly depends on what you do, and yes, for me the better software alone justifies a large part of the premium. The rest is for the large 16MB sample memory per channel, the I/Q Baseband player (not even available for the Siglent), PRBS generator (also not available for the Siglent) and the included GPIB interface (in addition to LAN and USB).As to the specs, yes, the SDG2000X looks better, but like many B-brand kit not everything is so great if you dig deeper. For example, the 33522B only has a max sample rate of 250MSa/s which is a lot lower than the (oversampled) 1.2GSa/s the SDG2000X offers, but at least the Keysight maintains the sample rate in all modes, including Arbitrary mode (where according to the spec sheet the Siglent drops down to 75MSa/s unless you use plain DDS mode).QuoteProbably, and there's no doubt that the Chinese B-brands have put a lot of pressure on the entry level market, which is great of course (something like the Rigol DS1054z wouldn't be possible otherwise).But the other truth is that the bottom end is the only sector the B-brand stuff is really attractive, and that vanes quickly the higher you climb the ladder.QuoteProbably, but I've seen first hand what Rigol and Siglent deliver in the entry level scope and AWG segment, and quite frankly it's pretty much only good when you take into account the low price for that gear. Some kit is also borderline useless, like the crap SDS2000 scope thanks to Siglent's ineptitude to write proper software for it. Shiny specs mean little if the instrument is buggy and produces unreliable results.QuoteYeah, sureNo seriously, what a stupid comment. Like any instrument, the 33522Bs are regularly used in various areas where using an AWG of that spec is appropriate. One of the labs I work in uses a few hundreds in ATEs, and the only 'backup' is a second 33522B so that if one fails it can be swapped quickly.Needless to say that mentioning Siglent or Rigol in such environments only earns you laughter (best case) or you're kicked out of the door (more likely).QuoteAs I said, fair enough, if the device suits your needs then great.But at the end of the day there's a reason why Keysight still sells a lot of 33522Bs and other expensive kit, despite the Chinese B-brands, and will most certainly continue to do so. It's probably very hard to understand for a hobbyist who often has enough time and doesn't have to rely on its kit (and for them using B-brand kit is certainly fine and a good way to get some half-decent kit at low costs) but once you have to rely on your test equipment or use it to earn some money then B-brands become more a liability than an advantage.The old saying "you get what you pay for" still holds true for test equipment.

content: IMHO Siglent does pretty OK with their signal generators but they should as it seems those are their first pieces of equipment they put on the market. The Siglent SDG1010 waveform generator I bought a couple of years ago serves me well as a function generator. I never bothered to use the PC software though and doubt the AWG functionality of the SDG1000 is usefull due to the short memory.Besides that if you need arbitrary waveforms you really need a decent software package to create waveforms otherwise an AWG is utterly useless. I used to own a Lecroy LW420 AWG but decided to sell it again because creating waveforms was way too tedious for my taste.

As you said as AWG is was pretty useless.QuoteThat is certainly true, and makes the fact that even the new SDG2000X comes with the abomination that is EasyWave even less understandable.QuoteWell, the LW420 is from the very early '90s so it's pretty ancient, and back then creating a decent waveform editor would have been a lot more difficult due to the limitations in computer performance and software. Having said that, you don't know what's pain until you tried manually entering a waveform in a Rigol DG1000z via its front panel

For hobbyists (which is the market Siglent and Rigol are primarily targetting) buying 2nd hand has long been a viable alternative, and it still is.QuoteYeah, whateverYour "experience" has obviously not prevented you from not understanding that you don't have to buy large quantities to get a good deal on the 2nd hand market.QuoteWell, you're pretty much showing all signs of rabid fanboi-ism. All I did was mentioning that I was pretty fed up with the quirks of the various B-brand kit I had and therefore went back to the big brands. I also explained the reasons for my dissatisfaction. For some reason that seems to have triggered some of your nerves.I said it before and I say it again, if you're happy with your Siglent kit then fine, there's nothing wrong with that. The fact that I wasn't satisfied with Siglent gear certainly doesn't invalidate your enjoyment of your kit, however just because you are obviously incapable to see beyond your own preferences and requirements my reasons for being dissatisfied with Siglent don't become any less valid.I posted this as a warning because people tend to get carried away by shiny boilerplate specs, and there's a lot more to a good instrument than just the spec sheet. It's also a reminder that the 2nd hand market can still be a viable option.QuoteAlmost but not quite. A big part of my job is *buying* test gear (a lot, actually), I'm on thebuyer's sideso pretty much on the opposite side of the big brands. That's why I know the T&M market (brand new as well as 2nd hand) very well, as I do know the various price gouging tactics employed by the big brands. And I can tell you that you're vastly overestimating the impact the cheap B-brands have on the big brands.

content: wow, this thread came back from the dead and escalated quickly. 'crap' is never definitive, treat it as a personal review of how feature, X, satisfies a single reviewer's needs.The only valid comparisons are with the variables that matter to your own purchase, when you make it; everything else are generalisations. Nobody is saying the Siglent isn't good value for money it's just that people value price, availability, confidence, features, bugs, support, warranties, new/used,... differently. Heck, even equipment that you may already own influences the 'right' choice when making a purchase.I just watched Dave's latest teardown of the new entry level R & S and thought that it has parallels to this price vs quality discussion. His excitement about quality (design, build and UI) and attention to detail epitomises most engineers' inherent appreciation of quality test equipment when they use it. Yes, he also acknowledges the price difference to Rigol.https://www.eevblog.com/forum/blog/eevblog-842-rohde-schwarz-hmo1202-oscilloscope-teardown/Disclaimer: I hate crappy user interfaces with a passion but I tolerate my Rigol (DS2072) because it's not totally abhorrent and I had budget constraints. I suspect I will be making similar trade-offs with AWG and end up with a Siglent (perhaps even a used 1020)!Sorry for the long post, it was Dave's enthusiasm for the R & S which reminded me why we like to own the Agisight kit even if some budgets can only justify the Riglents in the end.

content: Beauty is sometimes in the eye of the beholder.Without a doubt a Function Generator is a very useful piece of equipment - probably belongs in the first tier with a couple DMMs, a power supply, and an oscilloscope, or shortly thereafter.I started with a BK Precision 4040A about 12 years ago and it has coh ntinued to be a very good unit. About a year ago I became enamored with the idea of creating Arbs. Being a Rigol fan I looked at their Arb Gens very closely but after trying their PC software and the PC software of Siglent and others I went off the deep end and bought an Agilent 33522B. It is an excellent unit and the PC software is much better than the Rigol and Siglent software. In addition to the PC software the operations available on the front panel functions are top notch - you can do a lot with the 33522B. So - those are some considerations on the upside for the 33522B.On the other side of the coin, the 33522B has a front panel interface that isn't quirky but might be a tad short of highly intuitive (the functionality is strong but the UI is just a bit "different" in terms of button pushes and menu layers, etc.). It's probably just a matter of getting used to it but I'm betting over time Keysight will evolve the UI; I don't think they have hit a "classic" UI with the 33522B just yet. Their remote PC software is very functional when you get into it but it's again good rather than "classic" status. And beyond the UI the PC software plays in a sort of clumsy manner with Java sometimes, and the support team at Agilent/Keysight while very good is probably (definitely) stronger with test equipment than software.So, I'd give the 33522B an A- overall but if you factor in the price it's hard to give it more than a B+. Based on what I've seen (just from reading on the web) the new Siglent SDG2000X series might not meet or beat the 33522B on functionality across the board - especially if you need good PC-based software - but if you are going to be primarily operating the unit from the front panel then the price difference would seem to make the Siglent SDG2000X Arb Gens a no brainer. Between the bandwidth, features, and price the SDG2000X looks like a great choice. The only reservation I would have is if I was planning on building lots of arbs with the manufacturer supplied software.Just some thoughts....YMMV. EF

content: Maybe Dave could do a comparison of Siglent, Rigol, and Keysight Arb Generators - or maybe someone wants to suggest other manufacturers or specific models. For example, Tektronix Arb Gens don't come up here too often but Tek's software seems to be more in the Keysight league than the Siglent/Rigol league. Ideally, the review would have two parts: one on the front panel operations and one on the arb creation/editing process using a computer.

content: On a side note, the basic Tek arb is a rebadge that wasnt supported by the software. There was a thread here last year.

content: I didn't see a change log in the rar. I tried installing the new version (after uninstalling the old) and it continuously pops up errors when I start it up. I tried uninstalling and reinstalling again but kept having the same problems. For now I ended up uninstalling P34 and reinstalling P32. I may try to reinstall P34 again this weekend to see if I can figure out what is going on.

content: Quote from: tautech on January 21, 2016, 07:37:50 amTech support offered this:I just Uninstall the P32 easywave and install the P34, I can not repeat the issue.I guess that the customer did not uninstall the P32 cleanly.And I find that for some users have this issue:When he install the PC software ?If he select the "Just me" selection. His computer will not run the software.Not having the SDS2kX or needing to install the SW, I'm guessing this problem has something to do with the SW run permissions.....hope that helps.

content: Quote from: markone on January 20, 2016, 03:58:24 pmYeah, I used the word 'crap' to describe crap, how shockingWhat you (of course!) left out conveniently is that I usually also state why I concluded something is crap. I have owned Siglent and Rigol kit, and there are several devices of both manufacturers in my direct environment, so I do have a pretty good idea how they perform in the real world.For example, I know that EasyWave is crap because I had a Siglent AWG before and I saw first hand how goddamn awful it is. At work I use the tools that are available (for free!) for Keysight and Tek AWGs I have some pretty good idea how a decent waveform editor looks like, and EasyWave is so far away from that it's not even funny. Siglent *could* have taken ideas from the free Tek ArbExpress software if they really cared about the quality of their product (which for an AWG includes the software!), but they haven't. The SDS1020 I had also came with several firmware bugs but I could forgive them because the thing was so cheap. However, it also came with a major hardware flaw that caused excessive jitter in square wave mode, which I had to fix myself (a big name vendor would have just replaced the units in the field).I also know that Rigol isn't a lot better regarding its AWG software because I also had a Rigol AWG, and while Rigol's software was slightly less poor it was still more or less crap.I also know how bad the SDS2000 is because I had one myself. The v2 firmware has certainly seen some improvements but the state is still beta status at best, which for a scope that is on the market for two years now is pretty embarrassing. As you cerainly know with your "experience", a good test instrument has to be reliable and results reproduceable, and should not act in a random or unpredictable manner. Even with the latest firmware the SDS2000 fails on all accounts. Siglent seems to lack proper software development processes, and they obviously don't even do their own testing (at least not at an appropriate level) because they pretty much rely on user feedback for finding flaws, and that includes many that would be obvious to pretty much any user so if they had done some testing they would have found them themselves.So yes, if decent hardware is combined with shit software than the result can be, very much, a crap piece of kit.QuoteNot really. Like many others I've bought my fair share of crap, like the Siglent SDS2204, or the Rigol DS1062z. And had you actually read my other posts I made in this forum over the years then you would have found that I often recommend devices I know which don't own or I wouldn't buy myself (or adviced against buying kit I bought myself), if I feel it's appropriate for someone seeking advice. That on occasion even included Siglent and Rigol kit.I'm not saying the big brands are flawless, and there are a lot of things I'd criticize Keysight (or Tek, or LeCroy) for. But believing that the Chinese B-brands have found a magical solution to offer the same standard of kit as the big brands just at a much lower price is silly. The reason the Chinese gear is cheap is because they use generic off-the-shelf technology and components, they don't do complex stuff like research (while benefitting from others doing it) or developing their own ASICs because that costs a lot of money, and they cut lots of corners in design, testing, quality control and support (which they pretty much off-load to their dealers). Plus they benefit from cheap slave-like working conditions (most big brand kit comes from other countries including the US and Europe). This is also why Chinese B-brand kit is only really attractive at the bottom end of the market and gets increasingly unattractive in the higher market segments (and that isn't really going to change anytime soon).Of course its great that beginners now have a wide range of really cheap gear at low prices available, and a lot of that is pretty decent (for a beginner), and others like the Rigol DS1054z really hard to beat. And that is pretty much down to the Chinese B-brands, which lowered the costs for entering the electronics hobby dramatically.But there seems be some kind of cult particularly around both Chinese B-brands, probably because people see them in a similar way like say a Kickstarter startup - some young ambitious engineers who take their first step into business. Which sounds nice but ignores the reality which is that neither Rigol nor Siglent are startups but both seasoned manufacturers which are doing business for more than a decade, and which quite frankly should have sorted out major quirks. The fact they still haven't shows that not investing in better quality control pretty much shows that this is by purpose, i.e. part of their business strategy. Again, the kit of both brands is cheap for a reason.As I said before, there's nothing wrong with being satisfied with your Siglent/Rigol/whatever gear. If it fits your needs then good for you. There's also nothing wrong with buying B-brand gear as a starter. But one should be realistic, and understand that the low price is for a device which in build quality and support is appropriate to that price, and which does not necessarily reflect the reliability, performance or support that is generally expected from test equipment. It should be clear that a device which sells for a small part of the price of a big brand equivalent is cheap for a reason and will consequently suffer from bugs and issues which may or may not be fixed. That also means for those that value reliability and dependability and manufacturer support (or who don't want to support the slave labor conditions Chinese kit is often produced under), the 2nd hand market is still a viable option to new Chinese B-brand kit. So it shouldn't be dismissed right away as many seem to do, it's still useful to consider the potential 2nd hand alternatives before making a purchasing decision.I didn't think that this is so hard to understand, but thanks for showing me that I was wrong.
