AFE4300EVM-PDK: [AFE4300 Device GUI] How do Ro_Ohms and Ri_Ohms are calculated? (image attached)

Part Number: AFE4300EVM-PDK
Other Parts Discussed in Thread: AFE4300,

Hello,

I was using the AFE4300 Device GUI software to test out the performances of the AFE4300 Analog Front-end.

I had a 1kohm resistor on the J36 connector of the AFE4300EVM-PDK Evaluation Board, and I was wondering how Ro_Ohms and Ri_Ohms are calculated (see the IQ Measurement Intermediate Outputs in the image below) when I press the "Measure BCM" button.

Thank in advance,

best regards,

Lorenzo
