I am trying to measure capacitance using CN0552 on a raspberrypi. I am using ADI IIO Oscilloscope. I do not know which parameter to change to extend the range of measurement. Right now I think it is limited to 4pF.

AD7746
Production
The AD7745/AD7746 are a high resolution, S-? capacitance-to-digital converter (CDC). The capacitance to be measured is connected directly to the device...
