Most of the calculations cannot be done in PicoScope. But the measurements needed can be exported out. And could be easily be done in excel.
See this post on exporting measurement values-https://www.picotech.com/support/topic15481.html?hilit=batch
First you need to setup your channels and the measurements needed-
See the screen shot and example psdata file with-
-Channel A for- Volts
-Channel B for- Amps
-Maths channel - ChA x ChB (Instantaneous Power)
The measurements that are exported are-Volts- rms
Current(Amps) - rms
Apparent Power which is the DC average of Instantaneous Power (Volts x Amps)
Now follow the calculations in the attached pdf.
Here is Excel file with the calculations included-
I have not used complex numbers but you could do for some of the calculations.
