Can't wait for actual configurations & pricing and availability date !

I'm still in the market for an upgrade ...

EDIT: Found the answers I was looking for:  https://www.rohde-schwarz.com/th/products/test-and-measurement/oscilloscopes/rs-mxo-5-oscilloscope_334228.html

Cheers,
rudi

If that is so you could implement Frequency domain cross triggering. Now, that would be very nice...

I think the FFT is still operating downstream from the time domain acquisition so I don't think we can do that yet (at least not with high POI). I'd benefit greatly from being able to look at power/signal rails at low Fs and FFTs at high Fs, but I don't think the architecture supports this (yet?). You still have considerable freedom to adjust FFT settings on an acquisition -- wider RBW means you can fit more overlapped windows -- but I think they still need to fit in the time domain acquisition Fs/length, so you need to lengthen the time domain acquisition if you want small RBW and you need to store high frequency samples if you want a high max frequency in your FFT. R&S easily has the best FFTs given these constraints, but it is exactly because R&S makes RTSAs that operate on a gapless parallel stream (i.e. without these constraints) that hope springs eternal.



While you're at it, could you bring back deep voice guy too  ;D

I'm not sure I could take the pressure of competing with deep voice guy  ;D

--- Quote from: jjoonathan on October 31, 2023, 02:50:47 pm ---Regarding FFTs, do they operate on an independent parallel stream of time-domain samples so that low RBW and long fft acquisition time does not necessarily force long time domain acquisition time? Or do FFTs operate downstream of time domain acquisition so low RBW requires long acquisition? In any case, they look slick. 12 bits and loads of FFT/sec really makes beautiful spectra!

One of the strengths of the MXO series is that the FFT settings are independent of the time domain settings.  Here's a quick (1 min) explanation and demonstration from one of my team members:



We have lots and lots of experience with spectrum / frequency domain analysis at R&S :)

If the FFT can be adjusted without impacting the analog signal (from the video). Is this a parallel FFT/DDC processed in an FPGA along side an analog ADC stream of data that both end up both sharing the same memory? This would mean FFT/DDC doesn't rely on long analog acquisitions being acquired to calculate smaller RBW. So did you get around all the Tektronix patents? They basically wrote the book on the Mixed Domain Oscilloscope and then implemented it in their TEK049 ASIC. Believe this is why Keysight's EXR/MXR is a DDC in series after the ADC, both are not displayed or time correlated, but somehow yours is.

Now, that is a serious animal. The MXO5 of course. :)
