DHO900 SERIES | COMPACT SIZE, VARIOUS INTERFACES

The DHO900 series is RIGOL's high-performance economical digital oscilloscope. Though compact in design, it has superior performance. It features a capture rate up to 1,000,000 wfms/s (in UltraAcquire Mode), 50 Mpts memory depth, 12 bits resolution, and low noise.The DHO900 series supports 16 digital channels. One instrument can make an analysis on both the analog and digital signals to meet the embedded design and test scenarios. With an affordable price equivalent to purchasing an entry-level instrument, you can access the auto serial and parallel bus analysis, bode plot analysis, and other functions to meet the test demands in the R&D, education, and scientific research fields.

This little scope is a real powerhouse and the usability feel with the touchscreen is just great. I highly recommend this one as it also has a function generator output. Lots of stuff one can do with it. And I just even touched the basic functions. Anytime again.

This is a great unit for the price.I’ve read some negative reviews about hysterisis effects between the signal generator and the second probe circuit. Initially I thought I was getting the same however it turned out for me to be simply not grounding correctly (there’s a specific cable for this) and the shielding on the probes being, well, skimpy.Let’s go over the negatives first :I wish is that it had a connector for the signal generator, you get four probes in the box, and well I guess you can use one of those. But then you’re down to three channels worth of probes, it seems an oversight to not include one for the job.Downside of this price point is also that the more channels you use the more it eats into sample rates.Fan is just a tinge louder than I’d love too but not that annoying, just present. It’s not enough to bother me.Some recorded sampling seems locked to the view region, i.e. you see the waveform, navigate and find that it’s cut-off.The startup time is, yes, long. Feels like half a minute or so. For me this isn’t an issue. I turn on the unit for a session, not so often for a quick three second check-out of something. Would be nice if it were faster.IMO the upsides outweigh these small inconveniences.This is essentially the same as the larger brothers, just in a tiny package, all that stuff for way less. Way too many features to talk about in a short review, but this is a long way from those analog scopes of twenty or even ten years ago.The touchscreen is great and makes for intuitive workflow, it’s especially nice while navigating around the waveforms quickly.The footprint is really nice and small, if you’re making a mini-setup but need feature complete, this is perfect.USB powered, means you can have a truly mobile setup.Speaking of there’s a thriving modding community for this thing already, with mods to add an onboard battery.Price point for what you’re getting is as of today at least phenomenal.

This scope is clearly well made and the reviews on YouTube all do it justice. I was disappointed that I could not use the logic analyzer without an additional multi hundred dollar purchase. There are eBay alternative which I have now purchased for that logic, analyzer interface.

No está mal, pero hace mucho ruido y se calienta.

To co najważniejsze, to chyba wszyscy wiedzą - 12 bitów rozdzielczości wyznacza nowy standard oscyloskopów w tym przedziale cenowym. Moim zdaniem bardzo dobra jakość wykonania - na przykład w porównaniu z UPO2104E, w którym pokrętła są jakby luźno osadzone (luzy ok 1 mm) co jest przyczyną trudności w zadawaniu wartości lub przewijaniu menu. Ekran dotykowy zdecydowanie ułatwia obsługę, choć mógłby być o jeden cal większy. Zaawansowane funkcje. Zaskakująco stabilnie stoi na stole (szczególnie przy wciskaniu przycisków). Świetnie działa obsługa przez interfejs internetowy (w tym przez WiFi) i jest dobrym uzupełnieniem ekranu dotykowego. Możliwość montażu VESANajważniejsza z wad to oddzielny zasilacz, ta wada też jest przyczyną drugiej wady - zasilania przez delikatny port USBC. A przecież zasilacz nie jest duży i nie wpłynąłby znacząco na "przenośność" oscyloskopu. Ponadto solidne gniazdo IEC poprawiłoby niezawodność. Wbudowanie zasilacza nie wyklucza możliwości zasilania przez powerbank (tej opcji nie testowałem). Trzecia poważna wada, to hałas. Chyba każdy oscyloskop ma obecnie wbudowany wentylator, ale ten w RIGOLu jest szczególnie irytujący. Być może to specyficzna cecha mojego komputera/grafiki/monitora, bo okno podglądu na monitorze komputera wydaje się nieco nieostre. Trochę szkoda, że po wyłączeniu zasilania oscyloskop nie pamięta ostatnich nastaw. Wprawdzie można zapisać setup w pamięci oscyloskopu, ale gdy się tego nie zrobi to trzeba ustawić wszystko ponownie. Do innych drobiazgów zaliczyłbym brak zaślepki złącza sondy logicznej.

これまで同社のDS1054Zを使っていましたが、老眼が進んで画面の文字が見づらくなったことと、テープレコーダーのヘッド出力信号を観測したいと思って買いました。付属のプローブはもちろん4本ついていました。基本的には各チャンネルごとに調整しておくのが普通ですが、どれを使ってもキャリブレーション方形波の観測結果は同じで無調整で済みました。ノイズも少なく少年時代に購入したブラウン管オシロKIKUSUI 5520GRと同等のレベルでやっと小信号観測が無理なくできる機種に出会えました。そして内蔵のオシレーターがあるので机の上がコンパクトにできて嬉しいです。操作は画面が多いので使ううちになれるでしょう。いつも机上に出せないので電器店で購入したパソコンバッグに入れて使いやすいところに置いときます。

This professional osc-computer I will use for optimizing PWM converters, recovery or improving performance MPPT controllers. This device is better than I've ever used, but it's priced accordingly. It’s still unusual that the built-in OS takes quite a long time to load.

購入直後で未だ使い込んでいない状況でのレビューです。　開封直後の初めての通電チェック（プローブ未接続）において、CH1/CH2/CH3 は 0V を示すマーカーとトレースが一致しているのですが、 CH4 のみズレ（オフセット）ています。　オシロにバイアス・オフセットはつきもので、そのためにバイアス調整機能があるのですが、 CH 間での違いが気になります。初通電では何も調整せず、翌日に SelfCal を行うと、 CH4 のオフセットは解消しました。　しかし、次回通電においても CH4 のみオフセットが発生します。　通電後の経時変化は殆どない（初通電でのオフセット量と比較して）ので、起動時のオフセットは温度によるドリフト等ではなさそうです。　Setup の Load last は Default です、 最後の状態で起動する Last は未だ試していません。初期値設定に関するバグなのか、回路の初期不良なのか、あるいは「この程度の物」なのかの判定途上です。　基本性能に関わる部分なので気になっています。追記Setup の Load last=Last を試しましたが、電源OFF直前に SelfCal でゼロとなっていたオフセットが、電源再ONではズレた状態に戻りました。　その後に気付いたのですが、そのズレた状態では CH4 の垂直レンジスケールを変えるとオフセット絶対値が変わります（=SelfCal が効いていない）。　その他の CH1/CH2/CH3 では SelfCal が効いているようで、スケールを変えてもオフセットは一定（ほぼゼロ）です。　ファームウエアのバグっぽい感触です。　とりあえず、電源ON後に毎回の SelfCal でしのぐ他ない。初期不良で交換しようかと思って手続きを調べると、メーカーの不良確認が必要のようです。　しかし、メーカーの確認先が分かりません。
