Hi guys
Has anyone used the Hantek HDG2000-series with 16-bit res, or OWON AG1000s with 14-bit res?
The AWG seems to be one of the higher-end products Hantek makes and the photos of it and its display are pretty nice.
I can't find any prices for the OWON XDG-series and have enquired with the factory.
There seems to be a lot of 14-bit AWGs, like the Juntek JDS6600 with a rated sine THD of 0.8%.
Hantek HDG2000s are 0.1%
OWON AG1022 is 0.2%
OWON XDG3000s are 0.05%
I could not find any THDs listed for the AWGs that come built into any DSOs.
Somebody must own one of the above units? I know the JDS is popular.
I just had a look at Sigilent's site and the SDG6022X, 16-bit, 0.06% sine distortion <1MHz $1500 at Amazon - wowza
There is obviously more to the sine THD than just the bit resolution, since THD can be close to 1% from one manufacturer and less than 0.1% from another, with both models having the same bit count. It would seem that really low THD good enough for THD analysis is not possible with AWGs, but it is always appealing to me to have a low number there. I guess for most things that AWGs and DSOs do well it is better to have stable frequency and amplitude, and that is actually more important to me too, at least in my venturing into digital test equipment land goes.
I have some ppb fixed-frequency oscillators for real THD measuring.
