Looking to buy new scope for audio: R&S vs Keysight entry models
<< < (5/8) > >>
salomonander:
Thanks Antonio! Thats interesting. Do you know by any chance where the R&S lands in terms of speed?
And may i ask everyone why no one seems to like the R&S? Im just curious and want to learn.

I have been using a Hameg scope since late eighties and now use a Siglent 2000x plus and Magnova because the Hameg is no longer (RIP).

No issues wrt “slow”.

A lot of people love R&S. It is a very reputable manufacturer, and the MXO series are a thing of beauty. The problem is, they are not competitive at the <1500€ price range, and they don't want to.

The RTB2000 would be the closest competitor, and it is a really nice scope. There are a few reviews around youtube, but it is certainly not lag-free. Really, nobody has managed to optimize interface speed and responsiveness as much as Keysight with the Megazoom IV.

The Siglent is more analytical. It's oriented towards a more thoughtful use, with longer captures and later analysis. It doesn't seem to be what you are looking for. I'm very happy with mine, but you will notice hiccups on the captured waveform when diving into menus, the acquisition will visibly stop when moving traces, math and FFT will slow things out, etc. Quite normal, just like every other DSO except, for the most part, the KS Megazoom IV.

Edit: Have a look at youtube reviews. Skip to the reviewers' twiddling of knobs and selection of different modes of operation, and you will get an idea of each oscilloscope's responsiveness. Other than trying a bunch of them out, it's the next best thing. Instant response is a thing of the past, the only manufacturer that kept trying to emulate old CROs was KS.

the siglent looks interesting. But it being slow kills it for me. And i have read that everywhere so far. Im hardcore adhd and any kind of digital latency drives me mad in milliseconds :) I was not even aware that this might be an issue coming from an analog one. So i really need a super fast interface. Are all siglents like that?

That is why I cringe when some people just throw "en passant" comments, without explanation, at innocent bystanders.
It is easy to misunderstood.

On Siglent,  Frequency response plot is slower than that of Keysight at this time. But it is much better on the other hand, because it does averaging and selective frequency detection. Meaning it can get great results with small signals and even with lots of (electric) noise from environment..
Otherwise, all mentioned Siglent scopes are very fast with regards to user experience.

Hello,

for audio applications, a 16-bit PicoScope 4262 could also be of interest.

Best regards
