How did you find this?
Doesn't seem official yet.
It has "voice assistants."
Not sure what to make of it.
At least they differentiate now: Sampling rate 250Msa/s and Equivalent sample 500M
How did you find this?
I was looking for info about the DSO154pro, and
looking at their support page, I found this manual.
It probably won't be expensive.
The DMM specs aren't that great afaics. It doesn't even have a fuse at 10A.
It also has less storage depth and a weaker signal generator than the DSO2512G.
Right after the day my ZT702S arrived...
Is it worth the money now that is available on aliexpress, but not for 100$ .
I saw 110€ instead of 90€ or less I had expected.
Not sure if it will deliver or might only claim the specs like so many others before.
thanks

Yes, it costs $100.
You can't just convert the price that way.
Aliexpress has different prices for different countries which vary depending on taxes etc.
Your euro price includes VAT.
For example, the Swiss price does not include taxes (CHF 88.40).
Screen dumps from the manual:
The specifications have been changed.
Now the storage depth is also 128k, like on the DSO2512G.
I think the oscilloscope part is more or less taken over from the DSO2512G.
The screen is a bit bigger (3.2 inch), but I think the resolution is the same for the oscilloscope.
Apparently the signal generator is a little less powerful.
There are contradictory data here.
The ZEEWEII Official Store says "1Hz-2MHz", the manual says: "5MHz(sin) 1MHz(other)".
And "Note: When the set frequency is greater than 1MHz, the square wave signal may show small horizontal jitter".
On DSO2512G I have not seen such jitter.
I did buy one, just for trying out.

You must have a pretty big toy budget?

did get some unexpected money.
Zeeweii published a video on the voice assistant.
Its a missed chance that there is no reading out of the measured values in the DMM.

It's certainly fun, but I'm not sure I really would want to use this feature...
If the instrument works well, then the voice assistant is an amazing idea. While handling probes this can be very nice.

That's actually pretty impressive performance, seems to recognize and respond better than Alexa and Siri for me!
Agreed that it's more of a novelty that probably won't get used unless my hands are busy, but then it would come in really handy (*cough*).
"50Ohm termination!"
Poof!
Damn, these look good. Exactly what I need for my carry case.
I'm saving up for my Rigol DHO800 though. Decisions, decisions.
It is very interesting device! I have a few questions about it that are not clear from the video and manual:
1) The DMM may be used together with the DSO and generator and the DMM is galvanically isolated? If true it makes the device much more useful compared to other 2(3) in 1 devices.
2) How exactly works the reference waveform? Only a waveform currently on display can be used as a reference or also some trace saved in the memory? Does the reference scale and move with the corresponding channel when the sensitivity or time base is changed/moved? Two reference waveforms are shown in the pictures. I expect each one corresponds to one particular channel - is there an option to show only one of them (despite using both channels)? Or even use two references for a single channel?
3) Is the FFT useful? AFAIK DSO2512G only shows some graph without any indication about the quantities. I did not discover any way to know what frequency (or magnitude) a given peak has.

No one has this device yet, as far as I know. So one can only guess.
As I wrote above, I assume that the oscilloscope part was taken over from the DSO2512G. Everything looks pretty much the same to me.
The reference waveform is more or less a screenshot that does not react to sensitivity or time base.
FFT will also not be different from DSO2512G.
But for this price you can't expect miracles.
I know the device is very fresh. But sometimes the Aliexpress ships really quickly so I was hoping someone (RAPo?) already have one or may get one in coming days. The "marketing pictures" somewhat answer some of my questions (if they can be trusted):
To the DMM:
Built-in true RMS multimeter (...) osciloscope and multimeter may be used simultaneously (small window in the upper left corner)
That is promising, but
Use an isolation transformer + isolation optocoupler chip to isolate the multimeter from the oscilloscope, so you don't have to worry about common ground. (When measuring high voltage, the multimeter and oscilloscope cannot be used at the same time.)
What the phrase in the parenthesis means?
Also from the information available it seems the DMM is 3-5/6 digit (6000 counts) which is quite good but the current ranges are limited - only 600 mA and 10A range meaning only 100 uA resolution.
To the FFT:
Note: FFT can only display spectograms, frequency measurement is not supported.
The same as DSO2512G.

AFAIK my DSO2512G cannot show reference and cannot show the split screen Zoom view - those two features I am missingand consider them a great upgrade. Your DSO2512G can show the reference somehow?
