Hi,
I have succeeded to make RUU running.
But my main problem was the ntdll.dll error, which came back, and UtraSigma crashes.
I have tried few days everything that crossed to my mind with no luck.
By chance I think I found the problem.
I am curios to know if somebody else experienced similar errors.
The oscilloscope Rigol is connected to PC with USB cable.
I have other devices connected to the same PC with USB cables.
One of them is PICKit 3 programmer from Microchip.
When I plug in the PiCKit 3 from Microchip and I start and try to use UtraSigma, then I get that ntdll.dll error.
It is a conflict in allocation the USB resources between these devices, somehow reflected in ntdll.dll
The solution seems to avoid usage and connection in the same time of the Rigol oscilloscope+UtraSigma and PICKit 3 to be connected to the PC.
And I unlocked all the functions using "riglol-20140717.zip".
RUU works fine, but I did not try all its functions. For me, for the moment, it is enough screen capture, which can be done also from UtraSigma. I have to play more with record frames, but I did/do not use the record functions up to know on oscilloscope as it was not needed.
Maybe later the transfer of the waveforms will be good tool and help.
Analyzing the waveform in PC with a more complex software is better. I think DaDiSP is one of them.
I think, even decoding can be done like that.
The Power Analyzer software worked in trail mode. I guess there is no full free, eventually equivalent, version.
Again, additional offline software may be used to analyze the waveform from harmonics point of view, but a real time one would be better.
