There is another brandname they put on these generators! I just can't remember which :(
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

  israel, how is the software of the Siglent SDG1020 ? You can define waveform via mathematical equations ? Or simply combine basic waveforms and draw with the cursor ?

I do not know the control software for this generator, because did not come the cd of my unit in the package (if someone has it would be very grateful if provide one copy for my).  I asked to siglent  a couple of times unsuccessfully,

I guess that refers to software "EaSywave" to manage the generator via usb port.

Do they advertise the generator as being capable of arbitrary waveforms? If so, then it's very strange that they don't provide the software to define them. Do they expect you to input them from the front panel?

Just as a side note: the brilliant Agilent 33521A also doesn't include the software to create ARBs. Indeed it costs like >500€ extra. However the ARB files are just text files and the manual explains their syntax pretty well. Honestly I'm not sure if anybody really uses these arbitrary "paint" programs at all. Usually you have either a recorded signal of some kind of it's constructed this way or the other from a model or a script.

No, you get a basic version for free. Download the WaveformBuilder Pro trial version. After the trial period expires it continues to operate as Waveform Builder Basic. This is an intentional feature, not some accident or hack. It is how Agilent intended it to be. However, they aren't very open telling you about the Basic version and how to get it.

Compared to the Pro version the Basic version lacks a number of features. E.g. lots of filters and predefined waveforms are missing. But you do get working software.

Hm, maybe they changed that in a more recent version. Last time I tried (one year ago or so), the program simply refused to start after the end of the trial period. There was also absolutely no documentation available at this point how to get the non-Pro version and the Pro version did definitely NOT change in a non-Pro after the trial.
Then again, there's nothing in this GUI I want to use anyway. For the 33120A, I used the GUI only to upload the arbitrary waveforms, but on the 33521A there's no need for this either.

hi israel, I got their easywave long time before. If siglent still don't reply u, try this one.

My 1010 came with Easywave 1.0 on CD. It works ok, though I haven't used it extensively. I have not tried to direct connect the unit to the computer yet. I just transfer wave data files using a flash drive. (side note: Easywave runs ok in wine on Linux).

There are basic functions to draw things by hand, or you can enter equations.. I see trig functions and other sorts of math that you'd find on a scientific calculator. And you can import .csv data.

Externally , not sure about internals though ... But yeah , they look the same outside
I will compare the review of the ATF-20B and this one .

They are totally different!  If they littlebit looks ouside same kind it do not mean they are same.
After  30 second reading specifications it can know that they are not even cousins.

AFT 20B is very cheap made 8 bit resolution junk .. "lookslike nice" toy  made in Atten garace.
If example I try sell these I loose my faces totally.

SDG1000 is 14bit 125MSa/s with 2 independent channel tool made in Siglents best factory (not made in sub-contracting workshop). Not rollsroyce but in practice very good features/quality in its price class. Rigol 1022 is clearly also in other lower class. Of course have direct DDS advantages and disadvantages. (it is not PxP principle unit as also most of competitors in its price class)

And Atten (factory) is not Siglent (factory).
