Recommendation scope
« on: August 31, 2018, 05:36:17 pm »
Hi, sorry for my English. I've been reading here for many months, and I've decided to register. I'm looking to buy a scope for arduino projects as a hobby. My budget is 500€

I have seen mainly Siglent and Rigol, but I do not know if it's worth the price paying more for the Siglent.

Thanks,
Jose

You don't need the Siglent so it's a personal choice:

a) Rigol + Nice (soldering iron|power supply|multimeter)
or
b) Siglent.

Arduino projects are in the 10MHz range so both have more than enough bandwidth, etc.

Hello,

I would buy the Siglent SDS1104X-E.

The SDS1104X-E has lower noise (sensibler input).
It has max 500MS/s per channel.
Perhaps you can hack it to 200MHz.

In few years the money is forgotten but the better scope remains.

Best regards

I fully agree with that. Good tools are worth their money so keep saving for an R&S RTM3004  >:D

If the Rigol fits your needs then go with it. It is (still) a good choice especially for its low price. Use the money saved for getting some other useful stuff for your lab and be happy for years because you made maximum out of your budget. You could go for a fake HAKKO fx-951 e.g. and have still money left you saved for some other nice things you may need.

Right, because there aren't three ongoing threads of "Rigol vs. Siglent" at the top of this forum right now.

(and a fourth one half way down)

Everyone has different needs, different tools already in the lab and a different budget. The posters and the arguments seem to be the same every time, though. And they're very experienced forum members too.

True, but if the Siglent is unlockable (which I'm still not sure about) then the only sensible answer is still:

"The price difference tells you all you need to know, nobody else can help you decide".

In reality I think these people are trying to auto-convince themselves that they need to spend more on the Siglent when the reality is that they don't. They want everybody to join in and support their choice.

(am I a cynic?)

Maybe what's needed is more Owon-vs-Rigol threads so they can convince themselves they need the Rigol.  :popcorn:

true. in few years when you need to download data points to PC directly and quickly:
1) DS1054Z will be forever missed.
2) buy again the DS1054Z, and the next few years, the money is forgotten, now you have 2 scopes great!
>:D

The SDS1104X-E has lower noise (sensibler input).
practically... what you can make out of a 1mVpp noise floor of siglent vs 2mVpp of rigol? if you really need DUT noise investigation at those edges, you need something alot better than both...

You also need a really good DC offset ability so you can zoom in on signals that tiny. Neither the Rigol nor the Siglent have that.

nb. A nice, 24-bit PC sound card (maybe USB) works really well with audio and other small signals, much better than a low-range oscilloscope ever will.

Between the two oscilloscopes and assuming you already have other decent tools in your bench, I would go for the Siglent as it performs better.

If your goal is to save money while making the purchase, the Rigol is the intermediate option.

If you want to save even more money, a reasonably capable tool for Arduino projects with many additional features that a pure oscilloscope cannot give you is the Analog Discovery 2 - a swiss-army knife with a 30MHz oscilloscope (still perfectly suitable for Arduino-like projects), waveform generator, logic analyzer, etc. Several resident experts here recommend it.

Same answer as to Hongo. Thank

You're right, but maybe in every question about these oscilloscopes is associated with a specific need

I already have  tools in my bank, but not all are decent.

I do not need to save money, but since it's a hobby I do not want to spend more than 500€ (my wife would be angry)  :-\

I studied telecommunications engineering more than 20 years ago (the oscilloscopes were analog). I have no experience with digital scopes, although I do not think it will take me a long time to familiarize myself with it.

Later on maybe touch RF

I think a Siglent will be slightly more than that.


With a Rigol you'll have more than enough left over to take her out to dinner.

Did you look at the MicSig tbook series? These are also in your budget. The advantage is that these can run on internal batteries so they are more portable.

I bought the Rigol before the Siglent came to market.  I'm happy with it but...

Today I might give Siglent a harder look because it is supposed to have a better and more responsive user interface.  However, Rigol has been very responsive with several iterations of firmware upgrades over the years and AFAIK, all known bugs have been resolved (except 'Pluses' misspelling?)  I don't know how well Siglent responds to bug issues.

So, I would watch every review video and read every device specific thread.  In the case of Rigol, make sure the comments are current and relevant because there is a mega-thread that goes back to the beginning of time and things have changed.

The Siglent is also available with a higher bandwidth.  There is no condition under which a lower bandwidth is a feature.  You can always turn on bandwidth limiting if you don't want to see noise above 20 MHz.  Or you can add low pass filters in front of the scope.  There is never a condition under which a 2 GHz scope is inferior to a 5 MHz scope.  There may be a situation where the user doesn't know what they're looking at but that's not a scope issue.

To that end, I would want the 200 MHz version of the Siglent whether that meant paying money or performing some 'unlocking' procedure.

I'm not necessarily looking for another scope but the Siglent would get a lot of attention if I was.

It's all relative. Is the Rigol really showstoppingly slow?

"Better"?

With the Rigol it's easy to turn on measurements because it has a dedicated set of buttons on the left. Press button, measurement appears. With the Siglent it's a much longer process involving huge submenus and the multifunction knob.

I wouldn't trade a faster vertical movement for those measurement buttons, I know which will waste more time in the long run.

I'm not necessarily looking for another scope but the Siglent would get a lot of attention if I was.

Sure, the 200Mhz version is the next one that stands out in the bang-per-buck graphic.

That experience is a great advantage when moving to a DSO.
Not just the knowing of how to drive a scope but already understanding what you will see on the display.
Many that have only used DSO's do not fully understand that with this experience you can get most measurements from the display at just a glance.

One thing that will take some getting used to is some features are in menus, even sub menus as there is only so many buttons that can be placed on the front panel of a scope especially when they are in a small form factor.

What some newcomers to DSO's have complained about is the UI latency and for someone coming from CRO experience this can frustrate the user.
The Siglent X-E's are very snappy performers with very small UI latency due to their modern and fast processor.

For your stated use a SDS1202X-E with only 2 channels can provide some useful decoding results with careful selection of CS or CLK bus and trigger settings but with the 4ch models having the extra channels make for better decoding results.

I'm not aware of any appreciable difference between the oscilloscopes in that regard. I know you can send data to a computer with the DS1054Z and have the former crunch the FFT numbers, allowing for a many more point FFT.

I think that one has been pretty well settled to death. Having spent some time with a good DSO I'm a convert, for almost all typical users a DSO wins hands down. There are still two situations I can think of where an analog scope is superior. One is when you need some specific feature such as a good XY mode or the performance offered by some of the high end analog instruments where it would cost a bundle to get a DSO with the same bandwidth. The other situation is the low budget hobbyist, if you have <$100 to spend then analog is really the only option.

few years ago i used my PC USB FG with my DS1052E (or DS1054Z? i forgot) to do bode plot / impedance analysis similar to Dave's latest video using Bode 100 VNA. both of the FG (DDS3x25) and the scope... if you have some programming skill, you can pay $500 instead of the $5000 Bode 100 unit. attached are some capabilities you can do with the $500 PC+FG+DSO... i dont use the SW anymore since now i can afford something better but i think one day it will be handy if i dont want to risk or outside of input range of the more expensive equipment... ymmv.

That's exactly what I've been working on and doing with various pieces of equipment. Automation can be a wonderful thing.

I assume the Siglent has similar capabilities?

recently i rechecked siglent's manual there is indication it should can using WF or GCSV command? but i havent seen someone demonstrated it (not even in programming example in the manual) in real application, so i'm not sure. i think the manual is recent as istr it was not available in earlier dso model of siglent.

nice feature, but few points (1) i believed it is tied to siglent brand FG for proper automation. if we already have a FG or want to find cheaper version, then we have to do it manually just like the rest of DSO, otherwise we have to buy another FG or more expensive siglent brand  (2) sometime we need different setup, for example, instead of dB scale on Y axis, can it show |Z| value? built in feature is nice, but i dont think it can provide all users needs, so user programmability from "Raw" data input can open to a wider possibilities. other possibilities... what if i want to change the reference resistance from 50 ohm (in my 3rd attached picture) to other value and do custom calculation? deep length smaller RBW FFT as usually mentioned, etc... if someone can demo that data points from siglent dso can be downloaded to PC, i'll give it a thumbs up and worthy a mention from my recommendation department (the higher price of siglent instruments is another discussion though worth considering). ymmv.

Also in first message in same thread.

Sweep step 1Hz (center 999817Hz, Span 500 Hz, 501 data points.)
Not only this. It can do simultaneosly 3 channels BP.

And example this simple image tell real difference to competitors. Too easy simple cases what all can do, do not differentiate toys and tools. Some salesmen have said: "Scrap the Toys, Get a Real Oscilloscope". Just this...  :O

With Siglent it need what ever Siglent SDG. (in this example SDG1032X) Also some example LeCroy and BK precision etc some models (rebranded Siglents). Of course this is because generator need be under tight control of Scope.

so exactly... which one is real oscilloscope which one is toy oscilloscope? DS1054Z is toy? i think Keysight or R&S is real oscilloscope, more money more real ;) nevermind the big pocket guy, we bunch of poor people here. ps: dont trust the salesmen they only know how to sale they dont even know linux and even say no to you if you attempt command shell in a dso ;D

We thought it would be too but some have found ways around that and written scripts that interface between FG and SDS1*04X-E. It's in the thread somewhere about them and I'll come back after dinner with a link.

Some salesmen have said: "Scrap the Toys, Get a Real Oscilloscope". Just this...  :O

Salesman are supposed to say wanky things like that.  :-//

(And none of those phrases have ever been true in the whole of history - if it was another brand's slogan you'd be all indignant that your "Siglent isn't a toy!!")

"Some salesmen have said: "Scrap the Toys, Get a Real Oscilloscope". Just this...  :O
so exactly... which one is real oscilloscope which one is toy oscilloscope? DS1054Z is toy? i think Keysight or R&S is real oscilloscope, more money more real ;) nevermind the big pocket guy, we bunch of poor people here. ps: dont trust the salesmen they only know how to sale they dont even know linux and even say no to you if you attempt command shell in a dso ;D

It was ONLY for this image in message.
Try with Keysight entry level scope what have this phrase in salesmen brochures. And what advertise BodePlot function with big mouth. Siglent win it totally hands down, just totally. Just like total crap toy and real scope. (in this case what image show (and overall with BP) :| )

Of course then if we go to bit more upper class. There is nice professional lab grade and high end class scopes available from example LeCroy, R&S, Keysight and Tek. But world is changing and who knows how is this list in 2049

Old high end H-P equipment may example have front panel knob Optical encoder with ball bearings what never ever count single step wrong even if you random shake it how ever and it still last nearly infinite even if handle with heavy hand and gang.  Even one this component may cost same as today entry level "nice" Rigol or Siglent whole equipment or some others. Oh yes I have never seen if today Keysight have anymore these equipments what are also mechanically high end or even state of art class even with price tag as house.
My first scope when I was young was Heathkit IO-12  at 60's. (what a total crap if I think now but its time foir me it was miracle and still I learn lot of with this crap.)
Later I get some second hand 100MHz 60's Solartron and just after then I realize in real life what is total junk and what is tool (vs this heathkit "junk"). Of course later decades learn more when get more experience.

Now we talk scopes what new price is in class 1 - 5 day professional workman salary if we look normal somehow developed western countries! And then we look and nitpick details if this can be bit better or if this tiny detail is this or that... 

...but other hand... of course then it need understand that there is LOT of peoples who have extremely limited money for some hobby things if even for food. Then these are also expensive or very expensive. Some people may need save one year or even more for get one cheapest Rigol or Siglent.
When I was 7 year old I wait many months before I get ONE diode! (Chrystal detector for my self made Radio).

What is cheap crap for one, it may be expensive "crown jewel" to some other. And this can see here in messages. This is why also Rigol 1kZ is very good if compare what ever if want stand alone scope - If its price is buyer hard limit, how I can tell that use bit more and you get better.
I drive a LEC (low el. consumption) BEV car. Smoke exhaust pipes - go to museum. In Finland quite all electric power is made using nuclear, wind, solar and water.

For the 4ch X-E's, yes with the addition of an AWG.
Simple example:
https://www.eevblog.com/forum/testgear/siglent-sds1204x-e-released-for-domestic-markets-in-china/msg1435854/#msg1435854

And follow on in reply #550.
I was talking about the abilities of the oscilloscope itself. :) Can it read data back to a computer so that can do a many point FFT? Or have a computer trigger and read out the readings when combined with whatever AWG or SG you please? That obviously takes some programming, but is what Mechatrommer did.

In other words, does a user have enough control of the device through SCPI or similar commands to usefully use it in various testing setups without being locked into buying more Siglent gear?

All I care about in that regard, and all the typical user of a low cost scope is going to care about, is that there is a convenient way to get scope captures off the instrument and onto a PC. Someone who needs computer control of their test gear really should be buying proper professional grade equipment like Tek, Keysight, etc.

Why would that be so? The same could be argued for making measurements, with the same lack of tangible arguments. Rigol and Siglent wouldn't offer the options and connectivity if low cost oscilloscope users wouldn't care.

They offer it because it costs virtually nothing to include and it's another feature to list on the spec sheet. How often do you see a hobbyist using computer control of their scope? I tried it once just to see if I could make it work, haven't connected that since. I've seen a lot of youtube videos of people using scopes, can't think of a single time someone showed one being controlled by a computer. What sort of hobby projects are going to need or benefit from that?

Scopes like the Rigol are solidly aimed at the hobbyist/maker market and are entry level instruments. They offer a good value and can do a lot but I've never seen one on the bench in anywhere I've ever worked.

Doing a bode plot with a computer controlled AWG of a brand of your choosing and oscilloscope would be one application. Doing a many point FFT on a much more powerful computer would be another. Both are things that are of interest to even a casual user.

However, it's a moot discussion. The DS1054Z does both of these to a usable and useful degree. I simply want to know whether the Siglents can match this capability.

Using  SCPI commands 
WAVEFORM_SETUP | WFSU
WAVEFORM? | WF?
The waveform record must be read from the oscilloscope by the controller using two separate commands.
With setup you define data what you want, including possible decimation etc and with WF you ask data.

Programming Guide, version E02,  pages 178 to 191

And about communication pages 11 - 13 
( and other pages with examples )

there's germany sw that can even creates animated gif for that, and visadso can do that (among its other main features).

Someone who needs computer control of their test gear really should be buying proper professional grade equipment like Tek, Keysight, etc.
why have to buy more expensive if cheaper rigol can perform the task? (from hobbiest/poormen perspective, not a company nor rich guy)

I've seen a lot of youtube videos of people using scopes, can't think of a single time someone showed one being controlled by a computer. What sort of hobby projects are going to need or benefit from that?
i dont know but yes i agree controlling from PC like changing graph scales, turning on and off channels etc when we have dedicated buttons for that is just a gimmick. there is/are hobbiests tried to develop application for that but i suspect it will die soon after once or twice of use after its development completion life cycle. otoh we are talking about getting "data", technical or scientific or engineering or presentation data whatever you want to call it to PC. please differentiate between applications like bode/respond plotter or high resolution fft view (which only get important "raw" data and then post process it) with fancy PC remote control gimmick applications.

Scopes like the Rigol are solidly aimed at the hobbyist/maker market and are entry level instruments. They offer a good value and can do a lot but I've never seen one on the bench in anywhere I've ever worked.
so you still dont get it... rigol is for hobby (you said yourself)... but not available on professional desk why? how am i going to explain that? maybe just a simple question... is professional is a hobby? ;) why a big pocket company (or even person) buy a cheap when they can afford more branded one? if you have abundant of money, which one you are going to buy, a bettle car? or a ferrari car? but that doesnt mean bettle car is useless cant run and nobody want it right?

btw, another application i can think of (not yet needed so no program developed yet) is downloading logic analysis data. yeah yeah i know siglent has better logic decoder compared to rigol dont tell me that i've heard that like 100 times with proves cant argue with that anymore, but i have more superior cloned (:scared:) salae logic 8 for that purpose... unlimited memory and nice raw data export for external application post processing as well. i dont have yet a need or capability to observe pages (full memory) of decoded data in realtime blinking blinking in so many times per second on the dso screen, i guess people who sweared by the feature have the ability to do that... 30 rolling eyes per second.

i'm talking about if we have specific protocol, encrypted mystical stream only we know how to decode it on screen. or something undecodable in scope, such as if we know the data contains rows of color/monitor data, we can plot that graphically on pc screen, no dso i know can do this not even Keysight or Rohde and Swarczh. ymmv.

nice feature, but few points (1) i believed it is tied to siglent brand FG for proper automation.
We thought it would be too but some have found ways around that and written scripts that interface between FG and SDS1*04X-E. It's in the thread somewhere about them and I'll come back after dinner with a link.

nice video, but i am hoping he can download some data into the PC...

@james_s this is one application (from tautech's link/thread above) of how we want to control dso from pc to automate/synchronize with other instruments...
https://www.youtube.com/watch?v=7PvueUHAJ78&feature=youtu.be

but well, maybe your company has a proper and proffesional VNA for that purpose. we just use poorman method in hope to get the same (or close) result as proffesionals do at fractions of price. thats why its quite a shame to do a decent video using this poorman method.. ymmv.

this is another video, the well known (among the community) PyDSA FFT


edit:
another recently new thread, DS1054Z + FG as a VNA...

After meditating on which one to buy, I decided on the Siglent.

I know that the Rigol is enough, but the Siglent seems more modern, and will give me more benefits in the future, and as I said before, the price difference is not a problem.

Now I need advice on where to buy it in Europe, and if there is any kind of discount or offer that can benefit me.

Thanks for your trouble. From the overwhelming lack of people reporting that the Siglents are capable of this, I gather they're not or no one has actually tried?

You know if they apply some kind of discount for members of eevblog  and what is the procedure to get them?

Contact them and inform them you were pointed to them from EEVblog and ask for their best price so you can refer other sales to them from EEVblog.
You could try PM'ing member simone.pignatti as he works for an EU Siglent seller.
Good luck.
