Magnova oscilloscope

Sample rate is one of the most powerful selling points of all, and they will certainly not have voluntarily given up "more".
I don't know the architecture, but there may have been no other way.
More sample rate is "better", even if the bandwidth is not so high, keyword fast signals and their correct display.

[Fungus]

2x1.6 GSa/s sampling rate (while being capable of sampling at 4x1 GSa/s) seems like an unusual choice. Any idea why they would do that?

Maybe less crosstalk between channels at the slightly reduced rate...

Nobody has ever demonstrated I could hear a smartphone, so there's no point in my having one.

You don't know about messaging apps?

Not a phone call. Requires the other person to have access to the right app.

Good luck calling for an ambulance , or similar.The

Won't fit in trouser pocket alongside keys (for more than 5mins).

My phone has survived being dropped off a roof onto concrete. Daughter's can't survive someone gently sitting on it.

Bandwidth is king. Samples/s beyond the minimum necessary is marketing wank.

Good to see this device has a light mode GUI.

I think that still qualifies as a (Maxwell) SMART  Phone
From the discussion The Magnova Scope appears to be a fine device. I guess if I needed a new scope,I would consider it.. Now we have to wait till a few folks try it out.

It all depends on how well everything works when introduced. The specs can be great on paper but it needs to work for real. Too much vapourware is being put out nowadays and promises made features will be added after buying the product. Given the specs the development effort (and thus costs) to bring a product like this on the market is huge. You can easely sink a 7 digit euros figure into developing an oscilloscope like this due to the sheer amount of development time needed. It is a brave thing to bring out a product like this in a very competitive market but also very risky.

What would be interesting is whether this scope can bridge the gap between typical signal analysis oscilloscopes and oscilloscopes which are more suitable for doing embedded work. That would be a major achievement.

the signal acquisition rate of 300,000 wfms/s (12,000,000 wfms/s history mode) beats everything I know so far by light years.

300K is not even close to “beats everything”. Keysight 3000-series and up all do 1 million, and R&S MXO 4 and MXO 5 do 4.5 million.

We have just spent the first day of the trade fair with the premiere of the Magnova and would now like to respond briefly to your questions here in the forum. The basic data is already available, but the final data sheet is still in progress.
...

Professional videos, datasheet and manual will follow. We expect the series devices to be available in about 8 weeks.

Thanks for the update.  If you're interested in working something out, drop me a message.  I have no problem working with new products and am certainly willing to help iron out any problems.   I'm not too concerned about certification.

Hello,

I mean the 12,000,000 wfms/s history mode.

His own current MHO3 scope is likely quite close to that 300.000 peak with 360mpts in auto mem mode
If I recall the MHO3 unit got 230.000wfps/360mpts on paper, and Micsig had a tendency to undersell their ratings, which in practice were quite a bit higher.
but Keysight 3000 series, got what 4mpts?
Same with the 1000 series that got 2Mpts and on paper will do 200.000.. but one thing is specifications..
I remember Dave comparing Tek's new MSO2 series with an appalling slow update rate to Keysight DSOX1204G that peaked at around 50k to 55k..even though 200k on paper, but it's a long time ago so very likely something I missed.
But 300.000 with 320mpts in normal mode on Magnova is definitely a good start.

Hello,

the high wfms/s can only be achieved with small memory. With 3 Gpts/s, 36 kpts already require 12 us. The maximum wfms/s that can be achieved here is less than 84 kwfms/s. With larger memories than about 12 kpts, the specified 230000 wfms/s will not be achieved.

What are the highest waveforms you can encounter, is it 230k? the fact that it's highly timebase dependent is what it is, and the same across the scene,
but to make it somewhat apples to apples...Your highest peaked waveform update rate in normal/auto mode.
Did you try to follow the video from the MHO3 thread?? What waveform peak value did you get with that approach?? also at 50ns it peak'ed at?

To put Magnovas 300k in normal mode into perspective. the Tek2 series that resamples it a little and around the same base price.. the highest waveform update rate Dave could muster with it was around 18k with just 250 mem-points, and obviously also in a fast timebase mode like 10ns or 50ns, but 18k is pretty dang slow with 10mpts (per ch)... that is even slower than DHOxxx series (that according to Daves video) peaks at around 27k in normal mode.

The add-ons for the Magnova seem like a mixed bag, but mainly down to the fact that BW-SW update pricing reflect MSRP & not the current introductionary pricelevel.

Hello,

as I have written in the Micsig thread:
"
it is 8.1 Hz with 360 MS
and 40 Hz with 10 ns/div and 1.8 kS
50 kHz with segmented memory 1 ns/div and 1.8 kS and 10000 segments.
But the intervals between individual trigger points are sometimes only about 1.1 us.
"
It looks like there are still errors. I also cannot change the brightness of the waveform.

I would also like to have the direct display of the wfms/s....

[ebastler]

Yes, that caught my eye too. Whether one is just curious about scope performance, or wants to optimize the settings to search for rare events, it's convenient to have that information without the need for a counter on Trigger Out. Oh, and I guess bragging rights are yet another application for that display. 

[joeqsmith]

Guy turning the adjustment knob on the one video didn't seem to sure they wouldn't damage it.   

I'm curious how fast they can update the screen.  Also what techniques do they offer to look at deeper memory and how responsive is it.

the 200k waveforms per second on the keysight 1200x was after a firmware update. Dave said he didn't have the latest firmware on it and so it was limited to the original ~50k wfms/s

oooooooooooooooooooooo

What is the noise floor for different V/div settings?

[hpw]

What is the noise floor for different V/div settings?

Not only this:

- ENOB as most Siglent HD still at 8..9?

- ERES supported or as only full BW?

- Jitter of the reference clock see LeCroy figures for HD series 

- external clock connection?

- Custom Probe attenuation, Siglent 1E6...-1E6

- Custom color settings for trace and text ?

just my 2 cents, while those are not really cheap. IMHO. so real specifications to provide and not only to attract turtles / rubias.

Why do people love this weird way of displaying a waveform?
It seems to be the default amongst YouTubers but in my experience, is not really something which is used in practice.

The signal input is conventional AM as is shown on the signal generator display & the normal way to display it on a 'scope would be triggered by the modulation, showing several cycles of the RF envelope at the modulation frequency.

Such a display allows a rough measurement of modulation percentage & linearity, which are things which would be important to someone using AM.

The display which is commonly used in YouTube videos is triggered at carrier rate, showing several cycles at that frequency, with the waveform amplitude variation shown as in the above video, which may disclose some information, but just seems to be used for a "pretty" display.

Magnova are at least using it to obtain the time interval between zero crossings, although my old HP22s calculator disagrees a bit as to frequency for that time interval, but why not just use a CW carrier?

On reflection, the weird display may be useful for obtaining a very approximate measure for Incidental Carrier Phase Modulation,
The only time I have ever tested for ICPM was with an analog TV transmitter, & that was just because NEC showed how to do it in their handbook.

I wonder from a review standpoint, if using some of the X-Y analog scope, musical demos would be any benefit.  Obviously the idea is not to start the debate  of analog vs digital that we see repeating in the forums, but rather to get some feel as how they update the screen. 

[Antonio90]

¿Could we have a working example of the Bode/FRA feature?
What's the maximum frequency? Is it the 90MHz of the AWG?

With very little effort, and lowered memory depth, I was able to get a very responsive musical demo on my digital scope. I posted it in the SDS2000X Plus thread.
