hi
I see the Fnirsi-1014d comes with a built-in function generator.
For a very simple application, I don't need nothing but a portable device on battery with one analog line within audio bandwidth, and the possibility to generate a square wave at { 10Khz, 20Khz, ... 100Khz }, with variable duty cycle from 1% to 99%, and an output signal from 0v to 5V.
Is the built-in function generator able to do that?
I probably downloaded an introductory manual instead of the actual User Manual, but I can't find any more specifics about it
