🔍 DOS1104 Oscilloscope: Budget-Friendly 4-Channel Scope Review for Beginners

In this video, I'll be reviewing the DOS1104 oscilloscope from a newbie's perspective,
highlighting why it's the cheapest 4-channel scope on the market. We'll dive into its specifications, general appearance, and the various features it offers. Follow along as I unbox the accessories, explore the button layout, test the boot time, and perform initial testing. We'll also look into the functions, measurement options, and PC software integration. By the end, I'll share my pros and cons to help you decide if this oscilloscope is right for you.

Just a note. This is the same as the OWON SDS1104. Downloading its manual is much more elaborate.

Just ordered this scope. I'm exited to test it out 😊.
Huge upgrade from my DSO150, which has served me well though, but for audio design, i need 2channels, better sensitivity as well as FFT. For months I've been searching, comparing prices and specs and finally came across a great deal. I also like the usb power method.

Looks like the scope will help. Enjoy using it.

Mine didn't include a power wart/block, so i tried a 2A cellphone power wart/block. The signals were spiked, so i now use a atx's 5v tap and the signal is nice and clear.

Seems nice enough. Looks very similar to the Rigol I had. For what you paid for it, being a digital scope, it's hard to beat. Very usable.

Don't blow it up, though - USB does provide a path to ground if you connect to a computer that has a mains connection. so you will need a power bank if you want to prevent that.

I am just saying that for anyone who might not realise that - not necessarily you, if you already know. Great for a laptop on battery only, though.
👍My laptop is always mains powered because it is always on so I wouldn't want to power it from that. That would be an easy mistake to make.

Please don't take this as an horrible comment but as this is your first scope and it's like your first love ..Perfect ! might I suggest that you don't !! get used to the 'Autoset' buttons. I think it's better to try and approach the scope having a reasonable idea what you want to measure and set the timebase and amplitude first and if it won't work then its your get out of jail free card !!. Call me old fashioned but it's a great way to become aware of what you see at deeper level good luck with the subb's should be 1K soon...cheers !!!

Perhaps there is an option to keep the menu on screen which may then retain your setting when pressing run stop?

Heya, that looks like a very nice scoop I'm thinking of baying 1 so very nice to see this review wel done

[andymouse]

SQUEAK ! just subbed saw you on Dicky's channel thought I would have a look at your !!

4 channel Rigol dont cost 10 times more. You can buy Rigol DHO804 for double price of that DOS1104 scope. Also Rigol DHO804 can be easy hacked for free and with all of that it worth it to pay double in any aspect.

USB is NOT isolated from ground, BUT if you use a power brick, it will be. It is noce that you can power it that way. :)

[SINHRO-FAZA]

Питание данного осциллографа не совсем изолированно от сети, т.к. в каждом БП есть конденсатор, который связывает земляную клейму высоковольтной части с низковольтной на выходе из USB (для минимизации пульсаций, такое есть практически вов сех БП.), но данный осциллограф можно запитать от powerbank, и тогда щупом можно проверять высоковольтные сетевые приборы, не боясь спалить его внутренности.

Did you manage to store something in external drive. I am not able to…

Oh, yes - you can fry this thing. Grounds of all channels are still connected together and they float at the common voltage of ~90V, coming from the ungrounded switchmode PSU.
