First picture on EEVblog of the new R&S MXO4 series oscilloscope :)

jjoonathan:
Lively FFTs with spectrum analyzer controls are amazing when sniffing around for a signal that has been highly attenuated or superimposed on another. Even at low frequency the extreme dynamic range of spectrum analysis is a very useful complement to time domain capabilities. That's what brought me to R&S scopes, the MXO clearly takes it to the next level, and I've been sorely tempted by the MXO4 even though I really need to wait for the MXO6 (or whatever it winds up being called).

Hi! I think even non-regular-users of standalone spectrum analyzers will frequently find themselves using the SA capability on the MXO, they will pick up the benefits of it quickly. It is easier to use than older FFT functions in 'scopes, and different from the swept spectrum analyzers in terms of speed and the view it provides.

There's some video capture of it here. Often it can be challenging to see from the oscilloscope trace if there even is a problem (and where it could be originating from), but the spectral view reveals it.
(from time 9min24sec):

Obviously, I'm just a little biased here, but the MXO is the first oscilloscope I've been really excited about in a long time :)

The Keysight Megazoom IV ASIC is now over 12 years old  :o
Not even a sniff of the Megazoom V...

i still haven't done the teardown of the MXO  8)

I work on embedded firmware, these days smart-home devices operating in 900 MHz band. My office has DS1104Zs for us firmware guys and an older 3 GHz Tek MDO with a built-in spectrum analyzer claimed by our EE, but I'd like to have my own bit of kit. I'd prefer at least 200 MHz of bandwidth with an upgrade path to 1+ GHz, 4 analog channels, and I2C / SPI decoding. I2S would be nice too. I admittedly don't know whether a built-in SA is worth the premium for me; I don't get enough opportunity with the one at work to become proficient.

Nothing comes close to the MXO4 in terms of integrated spectrum analyser capability. It's pretty much a world apart from other scopes.


--- Quote ---In terms of budget, I'd feel great at $5k USD, good at $10k, and stretched thin by $20k. Before the MXO4 had been announced, I'd been looking at a Keysight MSOX3204G. The MXO4 out-specs it in a lot of ways and has a SA, but the MSO and protocol-decoding options drive the price up to $14k, and at that point I'm sorely tempted just to buy the bundle. At the same time my ill-nurtured thrifty side is encouraging me to seriously consider what I truly need and budget accordingly. The dream would be to pick up an MXO4 at the base price and purchase a promotional bundle of options for a song later on, but that might just be a dream. Any advice? I'm open to suggestions for other scopes too.

Talk to your local dealer, they might be able to do something for you in terms of bundling?
I'm not sure the Keysight 3000 would outspec the MXO in anything?

It doesn't, but it does include everything I know that I need for less than the MXO4 with the options I'd want. The specs were adequate (more than adequate, really) when I'd first considered it as an option, and they still are.

Good point with the local dealer, I'll investigate.
