Capable best value point

5.0

Pros - almost everything Cons - Fan noise on the high side - Time base adjustment is the only way to capture longer contiguous sample records Overall: highly recommended!

Value Leader in DSOs

5.0

I’ll try to keep this short, but there is a lot of value in this scope. Here are some of the things I feel are the most important to mention: Usability – This scope is really usable. I had a Rigol DS1054Z before and the UI was slow, the controls felt sluggish and unresponsive, and the overall experience wasn’t what I had hoped for. I was nervous to sell the scope I had to buy another unknown scope, but I’ve been completely happy with this Siglent. Features – While this scope doesn’t have all of the cool features of the 2000 and 5000 series, it still has a bunch for its price range. 1 Million Points FFT? Free IIC, SPI, UART, RS232, CAN and LIN on a $500 scope? Unheard of! 500uV/div vertical? Unheard of! Connectivity – The PC software isn’t great. In fact, I gave up. Who cares? It has a built-in webserver and optional (but expensive) WiFi. I don’t use the WiFi, it has an included Ethernet port and I had an old router laying around. I’d like to see free internal WiFi in the next generation. If you buy the option, it’s just a cheap USB dongle they included a driver for in the scope kernel. But if you use it, you can’t use a flash drive or power an external probe because there’s only 1 USB. Integration – The built-in Bode plot function can control a Siglent function generator over USB or Ethernet to generate a frequency response curve. That’s amazing! I spent hours putting together a Python script to do the same with my Rigol…the Siglent comes standard. Cons – The Logic Analyzer is expensive because all of the hardware is in the optional box, not the scope itself. For the $300 they want, you could probably do just as well with a Windows-based USB box, unless you absolutely HAD to synchronize it with analog channels. The single vertical control for 4 channels kinda stinks, but I definitely get it at this price point. It’s worth it to have the larger screen. Conclusion – You might be able to get a better scope, you might be able to get a cheaper scope, but I doubt you can find a better scope cheaper! Buy it. You won’t regret it!

Great student scope

5.0

The SDS1104X-E has unmatched value, only usurped for some by the new 1104X-U. Omissions from this new model include the 1M FFT and the possibility of 16 digital channels as well as some other minor changes like a 2ns/div max timebase vs the SDS1104X-E's 1ns/div. These feature are worth having in the 1104X-E, at least for me, especially when the sale price of an SDS1104X-E is so close to the RRP of the SDS1104X-U. The scope is very easy to use, though has some operational difference compared to other brands. Once familiar with it, its easy to setup measurements and acquire data. One of the strongest features of this scope is the serial decode, and other protocol decoding modes. This is often an addon or extra feature which is only reserved for more expensive scopes, but Siglent delivered. The massive memory depth is a must have over cheaper (or sometimes more expensive) scopes which can only capture data in the tens-of-thousands of points. Being able to single shot capture at a 14M memory depth and zoom all the way in to explore the signal is fantastic. Though do note that the 14M of memory is not always available at some timebases, the full memory depth can be found in the history mode, one of the operational differences I mentioned earlier. Certainly not as elegant as solutions from Keysight, but not a deal breaker for the price.

Web Browser Interface is Great

4.0

The web browser interface is really a great feature. With my old eyes having a real-time scope screen displayed on my 27” PC is outstanding. I do a lot of Arduino development and the web browser interface is a great addition to my workbench. The scope has tons of features and it seems that every day I learn a new useful aspect. There are a couple of minor inconveniences of that interface that I’m sure will be fixed with updates in the future, but they are really minor and if necessary a simple twist of the real scope control is always available if necessary. I’m new to the world of digital scopes and always assumed that digital scopes would miss some of the high frequency circuit glitches that sometimes occur developing new circuits. But I figured I could always reach for my trusty Tek boat anchor scopes if necessary. To my shock and surprise, the opposite turned out to be true. I see far more with the Siglent than I ever saw before. I’m still perplexed how this can be, but I suspect the higher BW of the Siglent is the answer. It’s an amazing testament to technology advancement of our modern times. I believe the web interface is only available on the four channel scope and initially I was reluctant to spend the extra money for something I didn’t need (4 chan). As fate would have it I started developing some stepper motor projects and the four channels were invaluable in that project. I also do some analog work on vintage amplifiers and simultaneously displaying the waveforms at each stage is excellent. I’m really happy I have four channels. The Siglent does have a minor shortcoming of not being able to zoom out from your captured waveform to see what happened before or after what is displayed on the scope screen. It’s my understanding that other digital scopes have that capability. You can zoom in (enlarge) the display, but you cannot zoom out. So you must recapture your waveform at a slower sweep rate (pardon my old school term) and then you can zoom, scroll, etc. to your heart’s content. Many times I simply use a slower sweep rate and zoom in if necessary. It’s a minor inconvenience, (hence 4 stars) and I have not found this to be a significant problem. Bottom line, I would buy this scope again.

Siglent vs Rigol

4.0

Like many, I went back and forth between the Siglent and the Rigol. I wanted the up to date internal architecture of the Siglent but was concerned about the layers of scroll through menus (versus buttons). Not to worry. It took me about 15 minutes to get used the Siglent. It's been an interesting ride from mini-fridge size vacuum tube scopes to today's compact affordable power-houses.
