Rigol MSO5074 vs DHO914s

<< < (7/10) > >>

Tarloth:
I agree with you, what gives me doubts is that the MSO5000 has already been around for 5 years and I suspect that they will stop supporting it soon. In that sense, the DHO surely has more bugs but it has a more modern design, it will age more slowly. I am very attracted to the 8GSa/s that allows me to detect glitches 3 times faster than those detected by the DHO, half of my use of the oscilloscope is that, detecting glitches (although to be honest they last longer than those detected even by the DHO ). The screen and independent controls per channel for the vertical one are a very strong advantage, but on the other hand those who have the MSO say that the interface is much slower and clunkier than that of the DHO.

The possible battery use of the DHO is also a very strong point in its favor since many times I have to monitor CAN lines far from the AC line but with 24 volts easily available. 12 bits don't really interest me, they are not a decisive factor but it scares me a little that everyone says that the analog front end of the MSO is really very noisy (how much?), but sometimes people exaggerate in order to favor the brand that has been bought versus the one that the neighbor bought.

I'm really in doubt, clearly there are features that I find very attractive about both but I don't have the budget to buy both. That's why I'm "desperately" asking for opinions from those who have them.

Thank you very much for any opinion you can give me.

The MSO5000 isn't going to stop working. They're not going to add more features to the DHO900.

What you see today is pretty much what you'll see five years from now.

Yep.

Doesn't matter for digital. Digital is all about timing and squareness of edges. Sample rate and bandwidth is king.

I have both the MSO5k and the DHO1000.  Sure, the 5k UI now looks a little dated as compared to that of the DHOs but I find it perfectly useable in absolute terms.  I don't perceive any lack of response, not to any significant degree.  And as it has already been said, the physical vertical controls I actually prefer, at least in my workflows.  It could be increased familiarity (I've had the 5k longer) but I actually find the 5k faster to use sometimes. YMMV.  The DHO screen is noticeably brighter, which is welcome but it's also significantly more reflective, so it's a mixed bag.

I initially bought the 5k rather than DHO, since I also am working predominantly in the digital/microcontroller domain.  My rationale being that the best bang for the buck comes from buying features you will benefit from e.g. significantly increased sample rate rather than those you won't e.g. 12-bit resolution.  Unless you're planning to work with small signal levels, the front-end noise argument is moot imho.

Also, you're likely younger than I am and may hence have better eyesight but - I'm glad I went with 9" and 10" screens respectively.  MSO operations with any significant number of channels on a 7" screen would be pushing it I think, at least for me.  You can, of course, always make use of the HDMI output on any of these machines but only if you want a monitor on your workbench too.

I'll add too that the reason I subsequently purchased the DHO was "because I can" and "it was cheap" (40% discount during Black Friday week) rather than needing to make up for any deficiency in the 5k.  It could still find it's way onto an auction site yet.



UK:
Sorry for being off topic, but when we talk about only digital signals, bigger screens and dreaming about working from battery power... why not just grab a logic analyzer + tablet/laptop with the desired screen size, instead of this big heavy guy MSO5000?!

For example something like DSLogic U3Pro32 for half of the price of MSO5104.

UK, now I have a LA connected to a laptop. Decoding signals from the PC has many disadvantages for me, it is perfectly usable but not ideal. Among the disadvantages is that whenever I need to decode it is because I have to see signal degradation at the same time the error occurs, so then I have to use the external LA, the laptop and the oscilloscope and on top of that I see the analog signal on a screen and the digital decoded in another. I prefer to see all in the same screen in real time to see jitters for example.

Another issue is that essentially the laptop plus the LA costs more than the oscilloscope, it's not as compact, and I don't have all the other features of the oscilloscope on hand or its robustness. Laptops can be fragile in field conditions and those that aren't cost much more than an oscilloscope in this price range.
