SIGLENT Digital Oscilloscope SDS814X HD 100MHz Frequency Band + 12 bit Vertical Resolution + Maximum 2 GSa/s Sample Rate + 4 Analog Channels + 50 Mpts Maximum Memory Length + 500,000 Wfms/s Waveform

This is pretty much the best Scope you can get at this price point, i got it for 54.8k inr. Its basically the SDS1104X-E but 12bit, higher sample rate, more memory and more features. Setting up your waveforms is a breeze with an external mouse which i did not know it supported. Generally i am reluctant to Touch Screens but this one is very responsive and snappy so it feels nice to use also the display is very high res. I preferred this much more to the Rigol DHO804 as the Rigo UI is pretty buggy and not as well setup as this one. Overall for this price point this is the best option. I had a PA license which i activated on this, it was nice to see that they give you free 30 tries for each paywalled feature but then again you need additional equipment to use them anayways and those equipment like the AWG etc come with a license key. Updated Review: After using and testing it for a while and upgrading it to 200MHz and installing additional options (which can be easily done 😉). Testing & Results: Bandwidth & Sampling Rate: I tested the 200 MHz model, and to my surprise, the actual -3 dB bandwidth came out at ~244 MHz even slightly exceeding its rating. With a 2 GSa/s sample rate, I expected a drop in performance when all four channels were on, but at 500 MSa/s across four channels, it still handled signals without excessive aliasing. Signal Accuracy & Noise: One thing I immediately noticed was the low noise level. I tested a 10 MHz square wave, and the rise time came out at ~1.5 ns, which is better than the 1.8 ns spec! Even at 200 MHz bandwidth, noise levels were impressively low, with a measured 2.4 nV/√Hz at 10 MHz, making signal details super clean. Triggering Performance: Trigger stability is rock solid. I measured jitter at just 4.85 ps RMS, which is far better than older analog trigger systems and comparable to higher end models. Even when testing noisy signals, the AC trigger coupling and noise rejection features helped maintain a stable trigger without false captures. Zoom & Sensitivity: One thing I love is that 500 µV/div is true resolution, not just software zoom. I tested the vertical zoom, and it maintained signal accuracy even at high magnifications, unlike some cheaper scopes that just stretch the waveform. Serial Decoding & Digital Channels: I ran some SPI decoding tests at 100 Mbps with all channels on, and it worked flawlessly. Even at 200 Mbps in 2 channel mode, the decoding was accurate, and the eye diagram looked clean something I didn't expect from a scope at this price! FFT & Bode Plot Performance: The FFT dynamic range hit 100 dB, which is way better than typical 12-bit scopes. I also ran a Bode plot test, and it nailed <0.3 dB amplitude error and <1° phase error up to 120 MHz, showing its accuracy in frequency response measurements. What Could Be Better? UI Takes Time to Learn: It’s feature-packed but not always intuitive. Took me a bit to find some advanced settings. But the UI is up there with Keysight scopes once you get used to it. No Built-In 50Ω Termination: If you’re dealing with high-speed signals, external termination is a must to avoid reflections. Since the SDS800X HD is an extremely affordable package, some corners had to be cut, one of them being the signal samples rendered as clusters of two vertical pixels (because of the limited amount of block RAM in the Xilinx Zynq FPGA). While this hardly poses constraints to our everyday tasks, there might still be situations where we want to get the maximum visual resolution for certain measurements. Final Thoughts Honestly, this scope punches way above its weight class. If you need high resolution, low noise, solid triggering, and reliable decoding, this is one of the best deals out there. Perfect for engineers, hobbyists, and students who want a pro level scope without spending a fortune. Highly recommended!

I like it. It arrived with 4 probes included in the box. Overall for regular use, the scope is pretty good. I deducted a star because I don't like that I have to buy an additional license to use Power Analysis features. They costs a decent amount (329$ if i remember right!). I think it should've been included in the scope. You can still measure all regular things using "Measure" but some cool stuff (power efficiency, measurement & more etc.) is locked behind software licenses. The touch works really well. It's intuitive and easy to learn. It's also not too thick so it fits easily on my desk. It get's the job done. You'll have to calibrate the probe that is shipped & I recommend you use the 10x option on that probe. The scope does not have auto-detection so you'll have to manually tell it that you switched to 10x under Ch1 menu. I attached a few photos of some waveforms I measured. It's still too early to say about the build quality & physical but yeah, it's a good scope. It could be better.
