DHO804

This is a solid workhorse scope for many practical applications for entry to intermediate level use. My personal use cases for this scope are audio (including synthesizers and other generated audio), and HF ham radio. For these purposes, 70mhz is perfectly adequate. Having 4 channels adds a great deal of utility. The controls have a slightly different arrangement than many other brands, but have the same essential functionality. These differences are mostly in the knob and button controls and their orientation. Menus are similar to how other brands are arranged with any differences only being minor. I have only worked with FFT in the math, and had success doing basic frequency analysis. Doing that and basic scope functions let me play with resolutions and scaling functions. Both horizontal and vertical adjustments work as expected and I was able to get useful visualizations and data. The package size and layout is great for my purposes, big enough to easily use, small enough to set up in a wide range of work areas. The screen is easy to read and presents cleanly. You can hook this to a larger monitor through the HDMI interface, but you do not have any visual resolution advantage. I will likely continue using just the built in screen, only. All in all, a practical scope at a reasonable price. It will be great for troubleshooting, signal tracing, as well as basic equipment calibrating.

Design: Rigol definitely stepped their game up this time. I've been using mostly Siglent due to better interface. Not this time. Rigol cleaned up the front panel, moved a lot of features into intuitive touch-screen menus. Hardware: Overall I feel like this is a pretty big leap over their older scopes in this price segment. This scope is basically an android tablet. It is tiny, gets powered by a USB-C power supply. Hardware is very power-efficient. Screen is responsive and precise. Probes are standard cheap BNC type. Perfectly adequate for 70MHz. Accuracy: For the price it is very good. The added resolution is nice, but I wouldn't say it's a game changer. I just don't work with that level precision in my garage. Triggering is still razor sharp. I heard there is a way to upgrade memory depth, which I guess could be very helpful if you're trying to catch a longer signal. Acquires AM and FM waves very accurately in AC-coupling mode. Functionality: It has all of the math features that you'd need. The FFT is blazing fast. This truly feels like a generational leap compared to last gen. Word on the block is that Rigol is using a custom ASIC to achieve such speeds. Areas to improve: I think the physical interface could be improved even more. Rigol does their typical Rigol thing with using different fonts around the panel. The included probe color rings don't match CH4. Honestly, the touch screen is so good that I would just consider using a 10" display and removing physical controls for the next iteration.

Solid scope for the price. Really nice quality and easy too use. Not sure if setting can be saved from use to use.

Many state the best bang for the price and feature rich. I believe it! Did initial testing and quite please with the results. Nice and small and compact and fits in my very limited workspace. Only negative thing it gave off a slight heat burning smell. Was aware of this from the reviews. So been turning on and leaving it on at least 8-12hrs. over last few days. And the smell seems to be going away. So just a new smell needing to be heated out over time. Wanted to go for cheaper 70mhz. but would have had to wait another week to 10 days. And was itching to get one so went with the 100mhz. and 4 channels tho have doubts i need 4. And it was delivered in 2 days. Quite Happy with it! As probably the best scope you can get for under $500 mark. And highly recommend it! A plus it is also hackable like the 70mhz to increase bandwith. The DHO 814 can be hacked to 250mhz,50Mpts,Can and Lin decoding.

Firstly, thanks to salicontech for making this oscope available in India. It is a great budget scope having 12bit ADC and 100 meg bandwidth. The build quality is quite sturdy. Two out of the 7 knobs have steps to them The resolution is also great as you get 25Mpts memory for single channel..... It has inbuilt measurement features (duh). It's touchscreen, so browsing around is a breeze. You can save photos of the signals on a pendrive and it has internal storage as well. Overall, a great buy for engg students or hobbyists.

12 bit: trace très fine et très peu de bruit. Vraiment mieux qu'un oscilloscope 8 bit. 4 canaux, 2 n'est pas suffisant pour faire du test. Très ergonomique avec l’écran tactile. Mémorise a l’arrêt le dernier réglage (c'est une option à activer dans un sous menu!). On peut sauvegarder les réglages et traces sur clef USB. Très léger et compacte. On peut l'alimenter par powerbank USB pour faire des mesures flottante ou en embarqué dans un endroit ou il n'y a pas de 220V. Logiciel PC non testé. Performance incroyable pour un prix dix fois inférieur aux marques d'oscilloscope anciennes (Tektronix...).

Ich nutze das RIGOL DHO804 nun seit einiger Zeit als Hobbytüftler und bin sehr zufrieden. Die Messwerte sind präzise, das Display ist scharf und gut ablesbar, und die Bedienung ist intuitiv. Besonders praktisch finde ich die 4 analogen Kanäle: Zwar habe ich sie bisher nie alle gleichzeitig gebraucht, aber 2 Kanäle wären mir schon mehrfach zu wenig gewesen. Das Gerät ist kompakt, leise und kann bei Bedarf auch mit einer Powerbank betrieben werden – allerdings sollte diese genügend Kapazität haben, da das Oszilloskop recht viel Strom zieht. Für einen kurzen mobilen Einsatz ist das aber durchaus praktikabel.

Generalnie jestem zadowolony z tego oscyloskopu. Ogółem - trzyma parametry, jest wygodny w użyciu, a z donglem WiFi umożliwia szybkie i wygodne przesyłanie obrazu do komputera. Jest jeden warty wspomnienia minus względem starego DS1052E, a mianowicie, według mnie prędkość próbkowania równa 1.25 GS/s jest niemalże wirtualna. Dlaczego? Ano dlatego, że chcąc wyzwalać się przebiegiem innym, niż oglądany, należy uruchomić któryś kolejny kanał, co powoduje spadek prędkości próbkowania o połowę. W przypadku starego Rigola użycie external trigger nie redukowało prędkości próbkowania (oczywiście załączenie drugiego kanału powodowało jej obniżenie, ale nie było konieczne dla wyzwalania drugim przebiegiem). Może i to jest specyficzny przypadek, ale dla mnie dość częsty, dlatego postrzegam to jako wadę. Oczywiście DHO804 jest mnóstwo przewag nad starym DS1052E, takich jak długi rekord pamięci niezależnie od prędkości próbkowania, 2 dodatkowe kanały, zasilanie z USB-C i wiele innych. Ogółem - jestem zadowolony z zakupu.

This is the full 100 mhz version. Some people buy the cheaper one and hack it to make the response 100 mhz + but I dont work that way. check out the eevblog for reviews and commentaries on the Rigol lineup. This scope will do everything I need a scope to do for the rest of my life. Other scopes around the same price have slightly more features, but this one has better resolution and everything I need.
