DS1104Z-S Plus 100 MHz Digital Oscilloscope with 4 Channels and 16 Digital Channels + 25 MHz Bandwidth with 2 Signal Source Channels

This scope does pretty much everything I could ask for. Solid 4 channel unit, compatible with their 16ch logic analyzer, and decodes several data formats. I haven't even scratched the surface of what this little beast can do. I wish it could decode rs232 serial and CAN, and maybe composite video as well (I mostly do microcontroller development and repair antique PCs) but for what it is this thing absolutely rocks.

This scope also has digital logic analyzer and a waveform generator (AWG). I've used all of these and found them to be highly functional and work properly. It's small and light weight, good for portability. The inputs and controls are clear and easy to understand. The inputs are 1 MegOhm with 10 MegOhm (10X) scope probes included. I purchased 50 Ohm inline loads for when I need an impedance match to a 50 Ohm cable. In all, this scope is wonderful for doing anything under 100 MHz - a real cute!

The multifunction knob—the one near top center—has no click stops. It matters. It makes the knob almost impossible to use, and it's important. If it weren't possible to replace the encoder with one that has stops, I would rate this whole scope as garbage. Replacing the encoder was the first thing I did when I got this, because I've used them before, and know the difference it makes. If I wrote a full review now, it would be long and say lots of good things. But none of them are as important as that cursed knob.

Excellent functionality and great user interface. A superb all in one instruent.

I love almost everything about this scope, but the one thing that really kills it for me is the small uppermost control knob. I've come to dread it. Rotationally, it's super touchy, making it difficult to dial in the number I'm shooting for, particularly in the numeric entry pages. I have the opposite problem when using it as a button: Half the time pushes don't register and I have to push it again, then in the process of pushing it I've moved the selection, so I get something other than the number I thought I'd highlighted. This frustrates me to no end, to have this problem on what would otherwise be a fantastic scope. I've considered wrapping the knob with several layers of rubber tape to increase its diameter and hopefully improve my ability to control it, but I've not taken the plunge and am not sure that would help matters at all. I'm baffled why this particular knob, which is multi-function and used to dial in so many critical values, is of such poor quality and small size. I'm also ironically frustrated that the rest of the scope is so good that I can't quite bring myself to return it, so I'm choosing to live with it even though it frankly kind of hurts. I wish there was some kind of remedy. If this weren't a brand new unit, I'd take it apart and see if I could fix or replace the knob, but I'm afraid I'm stuck with it.

the product is great and has lots of features, almost too many especially if your newer to oscilloscopes like I was. It took me a couple of hours of research to discover how to use some of the features and I still haven't used all of them. It also kinda sucks that the logic analyzer Function only works with a 200$ cable that I feel should have been included and shouldn't cost 200$ but other than that everything else is great and easy to use.

One of the few joys in life is receiving something like this. This piece of equipment made me smile from ear to ear. From the moment I turned it on and saw all the indicators go green I was wide eyed. I'm using it currently for doing repairs on old tube amps. I love that I have the ability to send out a signal on one end, and read the same exact signal on the other end as it's been distorted by the amp. I have the ability to record a signal at work, duplicate it, and send it back out all with the same machine. This thing is amazing. Highly recommended.

The feature set for the cost is a great value.

My old duel beam scope of 1985 vintage had been playing up for a while so after looking around for something new this popped up. It's pure luxury, 4-traces, all a different colour so no more trying to untangle two blue lines. Storage to hold loads of waveforms that you can zoom in on, so you have time to examine what happened and loads of measuring functions so you don't need to try to squint to see how many lines a wave is using. Still finding more things I can do, but at this price and this spec' its the very best value there is out there right now.

Super scope, lots of options. Love it!

El producto vino en perfectas condiciones, a tiempo y con todos los accesorios indicados. Producto excelente

Bon modèle d'oscillo, un remplacement pour les modèle cathodique que j'ai dans mon labo.

Super oscilloscope. Utilisation intuitive et appareil efficace. Bonne qualite.
