R&S to launch MXO5

[pdenisowski]

Aha, so it does allow setting the bandwidth!  IMHO that is a major differentiation from eres / highres modes and makes it much more useful.

What is the lowest bandwidth you can set for 'HD mode'?

When you enable HD mode, you select bandwidth in steps from 1 kHz to 300 MHz and the vertical resolution in bits is shown.

It would be nice if the marketing department could come up with a better term than HD mode.

Part of the reason I made the video was to explain the difference between "high resolution" mode and "high definition" mode.  I'm pretty sure we're going to stick with "high definition" mode but will probably phase out "high resolution" over time.  The MXO series only have HD mode.

And believe me, I have regular conversations with our marketing and product management teams about how we name things  

[nctnico]

Yeah, naming things can easely lead to heated discussions. At some customers I've seen products change names 3 or 4 times even after being introduced...

Ohh...
This would make it easy for me to display the sine from the PWMs...

Or a small ripple current on a current shunt (with the right probing solution though)

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!

Fortunately, most of the really awful / unfortunate product names get filtered out before release. 

Personally, I think the hassle involved in changing names after product introduction is usually not worth the benefit:  I can't remember a time when we (R&S) have ever changed the name of a product after launch, but that might be because most of our product names are just three letter combinations

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

Even if you choose a good name, someone else can spoil it. Back in school, I had an interview at a pharma company called "Isis Pharmaceuticals." Between scheduling the interview and attending it, the ISIS terror group popped into the news cycle with their brutal execution videos. I didn't make the connection until the next time I looked at my schedule and had to do a double take, lol. When I asked them, the consensus was "yeah, we'll probably have to change the name," and shortly thereafter they did. They are now "Ionis Pharmaceuticals."

Gentlemen, let us cut to the chase pricing would nice here

Does this mean sample rate and datastreams are independent (two different data pumps and streams)?
If that is so you could implement Frequency domain cross triggering. Now, that would be very nice...

Very exciting !

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

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

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.

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.

There are options in addition to always running ADC that has two full BW streams, one going to, let's call it, SA engine, and other going to triggering and paging and then to time domain scope engine.

They could pipe out data for SA after trigger engine (where it is still in full data rate) and before decimation. So you could have separate decimation and hence sample rate. I would still use same triggered blocks and route/decimate/process left and right.
Less throughput needed that way. Basically use same ping-pong buffers just route them left and right.

Also if triggering engine has such a low blind time, it could also simply copy time-domain /frequency domain block in time shared multiplexed fashion with same data pump...

Interesting...

Ok, it starts at 17K but what is the cost for an 8 channel 2Ghz model with three phase and power analysis options with two matching current probes and HVDP's

It's a bang3r.. but also out of most hobby-based-consumers' reach, at 17K and likely +25%VAT on top for the fun of it + options... Gonna stay a dream for many, unless you're financially polstered where the aspect of funds are relative or your a potent social media influencer.. that can "influence"

How common are these user-selectable hardware digital bandwidth filters on modern scopes? lowpass (FIR) / highpass etc.. where you can cycle it at will at your heart's desire on your full bandwidth.?

Seems the LPF/FIR-filter in these R&S like MXO5 goes from 1Khz to 300Mhz, quite a span... - what interval resolution..  1khz step?  can you swipe so you can see the waveform signal behave while adjusting the filter on the fly as that could be handy, or is it dial it in, and it will adjust accordingly but not continuously 1Khz to 300Mhz control.
The FIR filter (HD) seems to be controllable pr. individual channel, on these more flagship units like MXO5.

It's stepwise - I can post a list of steps if you'd like.  You can change the bandwidth and watching the waveform changing - this is actually how I often use that function.
