If didn't have already one, I'd buy it.
It's a great instrument for a good price.

Hey, don't really need one but I have a bad case of TEA. What's the postage to the UK?

 Sorry, I'm going to exercise some restraint for the time being. I already have one AWG, and another wavegen. This is nicer than both but I don't need it. Will keep watching

Does this definitely do 20Vpp into 50 ohm loads?

And can I assume that means it does 40Vpp into Hi-Z?

The datasheet seems to suggest otherwise.

If it does 40Vpp into Hi-Z then I may well be interested.

Datasheet indicates the following: 10mVpp to 10Vpp

How to get the Amplitude setting of the AFG3000 to read correctly.

If the scope has a 50 Ohm impedance setting, set the scope to his setting, or use an external 50 ohm termination.
If the Load is not 50 ohms then you need to tell the AFG3000 what the load value you are using. This may be set for each channel. To access these menus press Function key for the selected channel (i.e. Sine wave) then press Output Menu > Load Impedance. Here you may select 50 ohm, Load (any value from 0 - 10k ohm), or High Z (any value above 10 K ohm). Now the AFG will calculate the output voltage being applied based on the load impedance connected.

I really do not understand why this beauty is not sold yet.

I have already one.  |O

OK, I asked because your OP states:

Amplitude up to 20 Vp-p into 50 Ω Loads

I think that spec applies to the AWG3011 only, which often shares the same datasheet.

I am in the market for a 40Vpp Hi-Z (20Vpp 50 ohm) AFG/AWG, so this piqued my interest.

Could you not front it with an amp? I'm sure you've considered it (and presumably rejected it) so I'm interested in why that might not be an option. Of course, the desire not to spend a ton and then still have to mess around as well can be quite strong :)

I hacked one together myself with a simple op amp for occasional use, but I have to calibrate it each time.

For some reason 40Vpp function/arb generators aren't very common. The only two I'm aware of that might be a reasonable price are the Tek AWG3011 and the Philips/Fluke PM5138(A), but working ones are rare on the second hand market as far as I can see. Most generators seem to top out at 20Vpp into Hi-Z.

OK!

I imagine that it's much more expensive (the delta-V would be steeper, if nothing else) and somewhat nichey. The ARB is no doubt intended to provide a waveform and you do whatever is necessary to make that scale to your problem. Kind of like... er... [analogy bucket empty error]

FYI, if you don't mind having a huge function generator, I can recommend the HP 3325A or 3325B with option 002, which gives a 40Vpp output. Here's a broken one on fleabay with the option.
https://www.ebay.co.uk/itm/HP-3325A-Synthesizer-Function-Generator-Opt-002-High-Voltage-Output/122385762242?hash=item1c7ec287c2:g:qKMAAOSwImRYhWe3
There's so many on ebay of this type though I'm sure another working option 002 is out there or will be soon.

OK thanks for the tip, it’s appreciated.

I will ship the generator for free for 500 Euros within Europe.

40Vpp is a bit of an ask. Several of the Tabor ones do 32Vpp hi-z or 16Vpp into 50ohms:
https://www.taborelec.com/signal-sources-waveform-generators
They also do high voltage (400Vpp) amplifiers:
https://www.taborelec.com/High-Voltage-Amplifiers
But they are not cheap and I don't see them on ebay very often.

It’s actually only 24Vpp I need flr a particular test, but the next step seemed to be 40Vpp.

I have a reasonably easy workaround in the Op Amp solution, but it will complicate the test jig. FWIW I am using an ADA4870, I get an impressive 7ns rise time on a 24V swing and 50 ohm load.

What waveforms and frequenties are you looking for?
