Siglent SDS814X HD -12bits Mixed Signal Oscilloscope (4 Channel / 100 MHz)

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.

A very powerful scope for the price, well worth it.

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 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 ThoughtsHonestly, 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!

Scope performs beyond my expectations. I found adding a wireless mouse made waveform setup a breeze. A definite keeper for me.

SDS802オシロスコープはコストパフォーマンスが非常に高く、価格が手頃でありながら優れた性能を持っています。同タイプの他のオシロスコープと比べて、より良い機能を持ちながらも価格はより親しみやすいです。起動時間も速く、わずか30秒で起動します。操作の応答性もSDS802の大きな利点です。制御の応答速度が非常に速く、ユーザー操作のフィードバックはほぼ瞬時に返ってきます。これにより、ユーザーはパラメータを迅速に調整し、機能を切り替え、リアルタイムで観察することができ、スムーズかつ効率的な操作体験を提供します。操作インターフェースの設計も優れており、簡単に使いこなせます。すぐに各種機能や設定に慣れることができ、測定やトリガーの調整も簡単に行えます。高精細なタッチ液晶ディスプレイにより、波形や測定結果が鮮明に表示されます。総じて、SDS802は素晴らしい入門用オシロスコープです。価格が手頃で操作もスムーズ、測定と信号の分析が正確かつ信頼性があります。実験室でも現場でも信頼できるツールであり、エンジニアや電子工作マニアに強くお勧めします！

以前にSDS1000XシリーズとSDS5000Xシリーズを購入したことがありますが、今回はあるプロジェクトでリモートコントロールが必要で、SDS800シリーズを勧められました。まず3台購入して使用しましたが、PCから完璧にコントロールでき目標を達成できました。コストパフォーマンスが非常に高いです！ また、カスタマーサービスのスタッフはプロフェッショナルで、積極的かつ熱心に対応してくれ、サービスも行き届いています。大変満足しています！ノイズテスト：500µVレンジでのテストでは、ノイズRMSが約45-55µV程度であり、マニュアルで示されている標準的なパラメータを満たしています。2M点FFTテスト：テストにより、FFTと他の操作が衝突しないことが確認されました。これはおそらく独立したプロセスで行われているため、2M点FFT計算中でも他の操作が迅速に応答し、インタラクティブな操作性が非常に優れています。簡単に言えば、「カクつかない」ということです。周波数応答テスト：350MHzのホワイトノイズを入力してSDS804の周波数応答をテストしました。オシロスコープ自体の周波数応答は非常に良好で、明らかな楕円フィルター特性が見られます超高速エッジ応答テスト：500mV、85psの高速エッジ（LeCroy 10G帯域幅を使用）を入力し、SDS804の立上りエッジ測定結果は3.3ns、立上りオーバーシュートは6.6%であり、良好な結果を示しました。インパルス応答テスト：立上り時間は2.27nsで、周波数応答テスト結果と一致しています。周波数および振幅の正確性：1kHz、1Vppを入力し、表示は1.000012kHz、1.010000Vと正確です。まとめ：この新しいオシロスコープは優れた性能を持ち、操作がスムーズで、タッチスクリーンの使用感も非常に良いです。ネットワークに接続してパソコンで操作するのも非常にスムーズです。

For the price, it has the most features that work for me. Very well made and outstanding product. The only downside is the $350 additional probe that I was hoping was included, is not.

It works well!Also it has its own webserver accessible from the default IP address or give it an IP on your network at the office (check with your IT) and access it from anywhere in building.Really enjoyed using it for my project.
