content: 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.

content: Datasheet indicates the following: 10mVpp to 10VppHow 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.

content: Quote from: Teichhermelin on August 14, 2019, 03:40:41 amOK, I asked because your OP states:QuoteI 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.

content: QuoteCould 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

content: Quote from: dunkemhigh on August 14, 2019, 10:55:29 amI 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.

content: OK!QuoteI 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]

content: 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:qKMAAOSwImRYhWe3There's so many on ebay of this type though I'm sure another working option 002 is out there or will be soon.

content: Quote from: Howardlong on August 14, 2019, 12:51:05 pm40Vpp 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-generatorsThey also do high voltage (400Vpp) amplifiers:https://www.taborelec.com/High-Voltage-AmplifiersBut they are not cheap and I don't see them on ebay very often.

content: 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.
