I do not know if a scrollbar has advantages in speed or so - for a congruent and intuitive ui I guess it is not needed. In the FFT display there is no extra scrollbar - it is the FFT area itself. To change cf simply wipe through the FFT presentation. Of course the numeric entry field sometimes has an advantage, i.e. for large jumps or precise entries.
For advanced measurement users, it would be nice to have a button for the old overview of choices, to get directly to the wanted function. (Yeah, it is difficult to meet everybody's expectations...)

Btw., I now catch myself often trying to wipe over the display of my R&S SFQ...

New firmware 1.1.3 is available as of yesterday. 😎

[Martin72]

Version 1.1.3 (7th November 2024)
New functionality:
• Replaced Welch window with Gaussian window with regard to the FFT functionality.
Bugfixes:
• Fixed FFT RBW always corresponding to bin frequency, not considering window specific
bandwidth factors.
• Fixed LIN decoder not showing decoded data.

Should be mentioned.
I've already installed it.

 . Something Rigol didn't manage to sort in their scopes out over the past decade.

Had a discussion today at Elektronika Munich about their extraordinarily high ENOB numbers.

My claim that they are bullshit is correct, and they admitted it and promised to fix this in the next issue of their specs.
The guy who did the measurements simply took the level difference of an open input, ignoring all nonlinearities.

Anyway, looks like a useful scope but they need to step up with their measurement skills.

This is how its properly done:

It's a useful scope and no one is ever born perfect.
Considering this is their first game, it's doing well and in some ways better than other scopes from some established manufacturers.

This is how its properly done:

Most manufacturers measure the ENOBs at a significantly higher frequency, so will you update it accordingly with other frequencies?

As you can see on my pages the effort to do ENOB measurements correctly is considerable because all the filtering/verification has to be done for all frequencies of interest and there is no reuse of the parts.

A lot of companies publish at 10MHz because its showing the best numbers, usually. Better high bandwidth scopes do publish at a range of frequencies (like 10MHz, 100MHz, 500MHz, 1GHz, ...).

I dont have a Magnova scope, so they need to send me one to test it .

Thank you for visiting our booth at electronica and, of course, for pointing out the error. We apologise for it, we will recheck and fix this soon with an update to the data sheet.

Thank you very much for your suggestion! We would really like to have it tested by you as an independent expert. I will send you a direct e-mail.

[Wolfgang]

... we agreed to proceed with the testing as soon the SCPI layer is available.
This needed to run the automated test scripts I made for the other ENOB tests.

Hello,

thanks to all of you who visited us at Electronica 2024 in Munich: We met "first hour" Magnova owners in person, were able to discuss more in-depth questions and really appreciate the positive and constructive feedback we once again received.

Today, we release a new Firmware Package version 1.1.7, including some optimizations and bug fixes.
See a list of the contained changes below. All customers have been informed accordingly.

Version 1.1.7 (20th November 2024)
New functionality:

• Added smooth touch and mouse drag support for scrollable elements, for example the measurement selection.
• Added a textual indicator to show whether the Invert setting is active for analog channels.

Optimizations:

• Decoders now move without displaying a guide line when changing vertical position.
• Optimized component names in Information window for unambiguous identification of currently installed Firmware (Package) version.

Bugfixes:

• Fixed incorrect processing of active downsampling factor.
• Fixed Math channel grid labels not being updated under certain conditions.
• Fixed incorrect channel deskew parameterization at 1.6 GSa/s.
  A prior changelog incorrectly stated this issue was resolved.

Best regards,
Florian

The updates are coming thick and fast, which is great.
It's also nice that updating over LAN works so smoothly.
After that, I repeated the calibration, first in the cold state and then in the warm state.
Incidentally, I think it's much better when the device itself “tells” you that it's warm, instead of the vague information in the manuals that you would otherwise have, which says that it's warm after about XX minutes.
I also find it more logical if there are already umpteen temperature sensors on board that are read out, then you can also display when the device is in the thermally acclimatized range.

Really ?
Any test field technician should know this as well the target market for this range of equipment. 

I also find it more logical if there are already umpteen temperature sensors on board that are read out, then you can also display when the device is in the thermally acclimatized range.

In the hidden menus in Siglent DSO's this info is also available but users don't need to see it.....
Let the device reach operating temp before performing Self Cal or engage the Quick Cal feature.

[Martin72]

Stay cool Rob, nothing happened...
We all know about the importance of thermal stabilization and depending on the device, you can say, after an hour, OK, now it really has to be thermally stable.
However, it is more convenient if the device itself signals this to you, I also know this from the Lecroy models we have.

I had a quick play with one at Electrionica - seemed pretty impressive overall.

The most surprising thing to me was that they only had I think 3 or 4 units on their stand, literally surrounded by the competition from Siglent, Rigol and others.
I'd have though they'd try to make a bigger splash at this type of event

They sell those brands too. 😉

[Martin72]

"Buy our scopes! But don't forget to buy the others we have too."   

[Martin72]

Here are a few more pictures from the settings menu.
Previously, the Magnova had a rather long offset phase, but with the new strategy of (one-time) calibration in the cold and again in the warm state, this has fortunately been resolved.
The picture shows the offset in the cold state; almost nothing changes when the device is warm, which is very good.
There is also an advanced calibration, but with a warning that further measuring equipment is needed for this – a nice deterrent for the “I have to try everything” faction.
I had to smile at the “Fan Activation” point in the settings menu, see for yourself why...
What remains is the wish for a start screen, which you have during the firmware update process, by the way, you could also adopt that, @floBX.
And a shutdown message would also be nice, but both will certainly come with the next updates.

Yeah but they haven't got a crap-ton of development costs to recoup on those

[Sorama]

As of yesterday, the datasheet changed.

Anyone knows what in particular changed or was added?

[Martin72]

At first glance, the ENOB information has been omitted.
They will be measured again...

[woody]

In addition to the disappeared ENOB values:

The max passive cooling temperature has dropped from 40C to 35C.

The analog channel noise floor values changed for 20MHz and 350MHz and are given now for 100MHz and 200MHz. And the 200 µV/div and 6V/div values are new.

The memory depth per channel figures are upped a bit.

The waveform acquisition rate is given for a 100MHz signal frequency

The high resolution oversampling table is extended and changed.

Some math operators are added: log, abs, constant sqrt(2)

The FFT RBW is worded differently.

FFT window type Gaussian added

The Aux-output now has voltage and rise/fall time specs.

The Options are amended. Logic Analyser modules are now called Logic Probes, and the carrying case becomes available in Q1/2025 


And probably some stuff I overlooked.

[Andre77]

And probably some stuff I overlooked.

Thank you for the list!

I can only add two points:
- The maximum horizontal zoom factor has been increased from 100 to 100,000 (early firmware versions could only zoom up to a factor of 100).
- The total memory limit is now specified as 981.6 Mpts, whereas previously only the memory limit per recording was provided in the datasheet.

I see a trigger jitter spec has appeared. It would be nice though to know if the number is RMS or peak-peak

But jitter is in time domain, no amplitude…?

jitter (over time) has peak and RMS values
