Trying to create our own program for controlling the Velleman PCSU200.
We need however fast frequency changes, what is not possible in the software downloaded from Velleman.eu.
Changing frequencies ‘starts’ the generator again, leading to a small drop to 0V. This can be explained because the function SetGen is used at the moment, but SetGen(0,x,x) does not work in the .dll and the software provided on the website (velleman.eu/support/download … u200&type=). Ofcourse, the generator is started with StartGen and SetGen(ModeWeNeed,x,x).
With help of this forum (specially: viewtopic.php?f=11&t=8248) and using the software mentioned in that topic, but not made for this function generator, we can see the SetGen(0,x,x) mode does what we want it to do, change frequency without dropping to 0, however the bandwith is limited to 5KHz and the software is not written for this function generator so it is not possible to change the amplitude of the signal.
Request: improved .dll for controlling the PCSU200 with SetGen(0,x,x) working, and SetGen(0,x,x) working with frequencies > 5KHz
