THD measurement
We have used the ADC-42 scope together with SW Picoscope ver. 5.x for factory testing for many years with very good result. We have now bought a 2203 and try to measure the same parameters with Picoscope ver. 6.
The transfer is successful except for THD measuring. With the old SW we can set a maximum frequency for the FFT but I can’t find this option in the new SW so I get a terrible high maximum frequency in the spectrum window. The THD measurement is much higher than with the old SW which I suppose depends on noise in the high frequency region.
Have I missed something in the setup of the Picoscope or is there a work around?
Regards
Kenneth

Re: THD measurement
You can change the frequency range from the toolbar at the top. Please see attached image.
