SDS1202X-E

The other reviews mention many great features ranging from the 1GSPS, 200MHz bandwidth, FFT, and range V/div starting at 0.5mV. So i won't repeat these for the Siglent SDS1202X-E that I purchase on July 31, 2021. This is an excellent scope for the price. Don't let people mislead you into thinking that it's only for beginners (it's not) but certainly beginners will be able to use it. Compared with my HP54111d from the 1990s costing $20k when new and having 500MHz Bandwidth and 2Gsps, the little Siglent does far more and better for far less price (but only 1Gsps and 200MHz bandwidth). Others mention concern over the serial numbers and the 'droop' related to probe calibration. My serial number is not the BA. However, I will mention that the 'quick start guide' accompanying the unit had an addendum page regarding calibration that indicated the unit was calibrated several years ago which appears to indicate the unit left the factor at that time. So the BA serial numbers must have been fixed by then. Other people have mentioned concern over high levels of noise on the 0.5 mV through 5 mV ... actually not a problem. But here's my story. When I first started the unit on Monday around 4pm, I shorted the probe tip to its ground and noted wildly varying 'noise' on the 0.5mV - 2mV scale and that would make the scale useless. I removed the probe and instead attached a banana-to-coax adapter and shorted the two inputs with a wire. Whoa still wildly varying noise. Bringing my hand closer to it increased the noise by a factor of two. I began to think there was a problem with scopes ground circuitry to the BNC and some how the noise was coupling through the ground in some type of common mode problem. The FFT showed a spike at the frequency of the FM station down the road at 98.3 ... very cool. Decided to wait till the next day (Tuesday morning) for further tests. The environmental noise levels had dropped by Tuesday morning ... an interesting fact in its own right but still enough for testing. This time, a 50 Ohm cap was placed on the SDS1202X-E input BNC and also placed a 50 Ohm cap on the BNC of my old HP54111D (2GSPS, 500MHz bandwidth). Comparing the two showed similar noise in both on the 1mV scales - here the noise refers to the 'thickness' of the baselines and both were well below 0.5 mV. As a matter of fact the HP unit has dying internal boards that produce a baseline that wavers over about 0.5 mV. With the caps on the Siglent unit, moving the hand closer the 50 Ohm Cap does not result in the wildly varying noise levels. However touching the ground on the cap does result in the scope picking up a small periodic spike maybe 0.25 mV. I'll need to investigate the probes more closely since grounding the tip does not appear to eliminate the nose very well. Anyway, the scope does not appear to have an internal noise problem contrary to some reports. Finally, I wish the power cord could be attached at the back rather than the side of the unit since that uses valuable shelf space or maybe provide a right angle connector for the power cord. Oh and be sure to download the full manual from either the sellers website or the manufacturers website since the unit only comes with the quick start guide.

This is a review of the Siglent Technologies Digital Oscilloscope. I am a relative newbie to Arduino and electronics, building mostly stepper motor controllers, camera interfaces and experimenting with ESP8266 devices. For everything but the stepper motor controllers (joystick controller), I was getting by with multimeters and literally touching LEDs to different contacts to see what was hot. When I started building and facing issues getting the motors to run reliably, it was frustrating. Luckily, I caught a YouTube vid that explained how to use an oscilloscope to see what signal the Arduino was putting out (PCM to control the speed). I needed my own scope and not needing something fancy, bought a kit costing about $20. I built it, put it all together, then... nothing. Bought another one and was able to get it to work. Alas, it was glitchy. I did learn a lot about soldering and do recommend doing this, but it was unstable enough (my own fault) that I wanted a proper product. So I looked online and found a host of threads. Most pitted the Siglent against the Rigol, especially touting the number of channels in the latter. Other threads talked about the top-end frequency that each supported and how it affected the readings. It came down to the fact that a 4-channel high-frequency oscilloscope would cost about double what I was willing to spend. Though the Rigol and Siglent both had great reviews, I went with the Siglent as there would be easier calculations and adjustments for this newbie to make. The main things I like about this device was the high frequency support (200 MhZ) that would potentially allow me to troubleshoot more complex devices (e.g., video cards, radios, etc.). Two channels is one more than I'm using currently. Even for a newbie, the layout of the dials was easy to learn. Others have reported that the multiple button presses to get to math and other functions was annoying, but honestly, I use things like saving to USB and some of the math functions infrequently enough that it's not a concern. Display is easy to read. Calibrating the probes was easy using the included screwdriver and the built-in reference signal. I realize that $300 is on the high-side for a hobbyist (well, maybe :D), but after research this was most feature complete in that price range. I'm very happy with this purchase and hope to not soon outgrow it.

Adding to and changing my review: The other day I was trying different settings, and during this time I had the probe on a UHF and beyond with voltages possibly over .5KV. It stopped working. Knowing I had been *playing* with some settings I wasn't familiar with, I thought maybe there is some type of reset. The manual is tough to read so I searched online and found 3 ways to reset it. The second one did it and I was back in action. I'm liking this scope more each time I use it. It seems to go into *sleep* mode too soon, I haven't timed it. I did think that it was... Pretty darn good for the price. I've been using it for a couple months with no complaints. I really like the auto adjust feature or whatever it's called. No searching for your waveform and amplitude, one button will adjust it. So far the ONLY drawback is the boot up time. My old CRT Tektronix is ten times faster. But that's only once a day so no big deal. I had tried a cheaper one but it had too much "static" on DC waveforms.

My order arrived on time and in good condition. ( Nine months later, still working fine!) This is only my 4th oscilloscope purchase and replaces my Tektronix 2215. Maybe it's because I watched so many review videos first, but I picked up the user interface pretty quickly and have been trying out the 'scope for the last two weeks. The main points I like are the deep memory depth (up to 14 million samples, split between two channels) and the serial decode function (handy for Arduino and Raspberry Pi and other microcontroller peripherals). Other great features I enjoy are one-button screen captures to a USB stick, and the novelty of operating the scope remotely over the Ethernet LAN port built in. I was a little disappointed that this 2-channel model doesn't include the Web server remote display option like the 4-channel edition; you have to install a special software package to drive it over the network. Be aware of network security concerns discussed on the Web, though it's never going to trouble me on my household network. A blunder I made when ordering was to order from .com, not .ca, so I was charged significant extra import duty even though this scope shipped from Mississauga. (Edit: Shortly after posting this, I was credited back with the difference.) Serial decode was the main reason I chose this over other makes; I'm still trying it out and find it a little difficult to set up. You can' t use "trigger in" as a clock signal, so you can pick only one direction of an SPI bus to monitor, for example. I can't see how to invert logic levels to directly monitor RS 232 with the UART protocol; it seems hard-wired to expect logic 1 is the higher of two voltages, though you can change the threshold (if I'm just monitoring one channel I can invert probe and ground, if the source is isolated from ground). Works fine on 5 V UART signals, though. Tried it on "oscilloscope music" but found it was easier to get a good picture on an analog scope; this is not a great limitation. I find the screen resolution to be pleasantly high and I am glad I didn't purchase other models with fewer screen pixels. All scopes are microphonic to some degree; I tried this one and found I had to tap it pretty hard with a pencil, especially right around the BNC connectors, to get it to false trigger. Now I that I know that, I won't do that any more. When I was in university, getting all these features would have cost as much as a small house and taken a wall full of equipment - it's amazing what technology you can get for so little money. After nine months on my bench I'm still very happy with this instrument.

First, full disclosure: I had to return this scope, due to no fault of Siglent's. I bought used on Amazon Warehouse and mine came with problems. I've been a Siglent user for many years. I love their interface. Love how clean and simple everything is. For the price, 200MHz is absolutely insane. You can analyze FM radio stations. Build quality is absolutely magnificent. Solid, heavy. Buttons are very firm and tactile. Screen is clear and bright. Probes are cheap generic type, but they work just fine. I haven't' had any issues with accuracy or signal acquisition. FFT is a little slow compared to new Rigol 12 bit models. But this is a pretty dated model. Dave from EEVBlog is right - considering how cheap the 4 channel scopes are these days - just save a little extra cash and get the 4 channel one. Unless you absolutely need 200MHz and the sampling rate. Summary: Great scope for the price. Hopefully Siglent starts offering some pretty substantial discounts soon, because they already have the next-gen 12 bit scopes out for very similar price. And right now Rigol's value proposition is even more aggressive. Still, if you're a fan of older scopes with physical interfaces - this scope is a great choice.

I'm quite familiar with old, bulky CRT Oscilloscopes back during my school days - However, I've recently integrated a Tektronics digital oscilloscope for my customer (I fabricate industrial test equipment for a living) and I've been itching to get one for my personal use. The SDS1202X-E , For the price point of 370+ USD has decent specs (200 Mhz, 2x channels , USB/ LAN, features) and a good contrast Screen. The package comes with 2x 200 Mhz (1x,10x attenuating ) probes, 1xUSBTypeA to USB type B cable, & a Calibration Certificate. It has a serial trigger feature (for CANBUS , RS232 & more ) and Math functions , but I've yet to test those out. I'm also not sure if this model has the serial decoding feature as well. Construction of the unit seems like what you'd normally find of similar range of Oscilloscopes - ABS/PVC injected body. The push-buttons are silicone and have LED backlights to indicate operation which I personally prefer compared to hard ABS buttons. The rotary knobs have notches? internally, so you have haptic feedback during rotation (like on old normal mousewheels - not the infinitely free spinning kind you see on gaming mice) For people concerned about calibration, there are no specific units mentioned on the calibration sheet. However, they have listed the calibration equipment used (e.g. Keysight B2901A - Precision Source/Measure unit and others) to validate the unit - and of course they have a certificate no. which is certified NIST / NIM/ NPL traceable. All-in-all, Would recommend this product for hobbyists and beginners!

This review is for the Siglent SDS1202X-E oscilloscope. I bought this to replace a PC/USB O-scope I purchased a few years ago - and I'm so glad I did. For the home hobbyist, this scope has exceptional value. Starting with the bandwidth, ability to decode Serial, CAN, I2C and SPI. On-board FFT. And overall exceptional build quality. The feel of the dials is comparable to top end units (I have a 2GHz scope at work - I know what expensive controls feel like). The only complaint is the lack of any manuals to show a novice user how to make use of all the capabilities this scope has. Because I've used scopes on and off throughout my career, it was super easy to use, straight out of the box. But for someone with no experience, it can be daunting. I have saved custom configurations to memory, recalled setups from memory, and used it to train a class at my workplace (I don't want to risk my 2GHz scope with ham fisted employees). As I'm about to retire, I wanted to have a good scope for home - and this scope has exceeded every expectation I had at the price point. Would highly recommend this over other brands in a similar price point/price range.

I gotta say, I am so happy with this scope I got two of them! I'm old school, used to multi-thousand-dollar scopes to get these features but this thing actually does a better job in everything except perhaps reaction time (event-to-screen-update) and probe characteristics. Of course, since it is basically a storage scope, these are non-problems. The user interface is very good... I'm not going to dock it any stars for the decode display being a bit hard to use, it does such a good job with everything else! I am easily getting the advertised 100Mhz. The sensitivity is good. The capacitive reactance of the probes definitely overshoot a bit relative to an expensive Tek scope and high-end probes, but it does not interfere with operation. I really like the stand-alone nature of the scope. You are not required to hook it up to a computer or network to use all the functions. And that's how I use it... stand-alone. My computer's screen real-estate is needed for other things. I really like the short depth of these modern scopes. I can pack it right up against the back of the desk and have a ton of room to work in front of it, and stacking two of them on top of each other is not a problem. -Matt

Zu der Lieferzeit, den technischen Daten, Bildschirm, Haptik, Lüftergeräuschen usw. wurde schon fast alles beschrieben. Hier noch einige persönliche Tests und Eindrücke die ggf. bei der Kaufentscheidung helfen können. Decodierung: In meiner alten Firma war es möglich das Decodieren verschiedener Protokolle unter Zuhilfenahme eines Testboards zu analysieren. Nach der Korrektur verschiedener Einstellungen war dies möglich. Die Decodierung ging sehr schnell. Wenn man etwas in Echtzeit haben möchte, muss man halt das mehrfache investieren. Die Funktion ist auf jeden Fall gegeben. Für den Hobbybereich sind die gegebenen Möglichkeiten auf jeden Fall ausreichend. Die CAN oder LIN Signale werden wohl kaum benötigt. Ich habe ein paar Screenshots beigefügt. FFT: Die Fast Fourier Transformation macht was sie soll. Alle notwendigen Parameter sind editierbar. Eine Vollbildanzeige ist möglich. Alles geht recht zügig. Die Signale im Screenshot sind sehr schwache UKW Sendesignale. Als Antenne habe ich nur zwei Kabel (ca. 200 und 500 mm) genommen. Für einen Keller im Betonbau sind die recht gut. Mobilempfang = 0, Radioempfang kaum möglich. Setups: Es lassen sich Einstellungen für das Setup, Referenzen, die Setup Taste und Screenshots speichern (Extern USB oder intern). Für mich sehr wichtig. Externe Steuerung:: Die Steuerung des Siglent kann über USB oder LAN zum Beispiel mit der Software EasyScopeX erfolgen. Diese kann man auch auf der Homepage von Siglent herunterladen. Siehe Screenshot. Die Installation ging problemlos. Die Bedienung geht natürlich nicht in Echtzeit ist aber sehr flott und alle Funktionalitäten sind gegeben. Echtzeit kostet halt echt viel Geld. Zum Service bei Siglent: Ich kann denen, die von einem schlechten Service sprechen nur widersprechen. Ich hatte wegen einer Frage angerufen (Deutsche Niederlassung) und wurde zunächst von einem kompetenten Mitarbeiter beraten, der mich sofort an einen weiteren Mitarbeiter der Fachabteilung weiterleitete. Alles ohne Warteschleifen. Nach Aufnahme des Problems habe ich innerhalb von zwei Stunden eine Antwort per Email erhalten. Das kenne ich so nicht. Gruß an Herrn R. und Herrn W. Negatives: Es gibt sehr viel Licht beim 1202X-E aber auch ein klein wenig Schatten. 1. Bei der Funktion Menü Off werden nicht alle Menüs ausgeblendet. Lediglich die Menüs am unteren Bildschirm verschwinden. Diese Lösung ist aber noch immer besser als bei bekannten Mitbewerbern. 2. Der externe Trigger ist nicht komplett freigeschaltet. Für meine Anwendungen jedoch vollkommen ausreichend. Fazit: Ich kenne kein Gerät mit diesen Leistungsmerkmalen das zu diesem Preis angeboten wird. Das letzte Firmwareupdate hat nochmals einiges verbessert. Ich kann das Gerät guten Gewissens empfehlen. Man macht nichts falsch. Daher volle 5 Punkte

This dual-channel oscilloscope is an excellent device for those who only need two channels. Its price-to-quality ratio is ideal. Highly recommended!

Ce Siglent SDS1202X-E est un très bon oscilloscope jusqu'à 200Mhz il y a de quoi analyser beaucoup de différents signaux ! Je l'utilise fréquemment et les résultats ont toujours été très bons ! J'ai pourtant 5 autres gros oscilloscopes et celui-ci est l'un de mes favoris tellement qu'il est performant ! Je recommande fortement cet appareil de laboratoire !

Ottimo oscilloscopio, economico

Je me sers de cet appareil depuis plusieurs semaines et je suis pleinement satisfait de la qualité du produit. Il s'agit d'un instrument de précision à la fois compact et facile à utiliser. Étant donné que c'est mon premier oscilloscope, j'ai consulté de nombreuses revues en ligne qui attestent de son efficacité pour les besoins spécifiques auxquels je l'utilise. Je le recommande vivement.
