I want to use a Rsense of 1 Meg Ohm to measure the impedance of electric guitar pickups. I guess I would need to short cut Rsense during the open circuit calibration. Other wise the gain diffrence between left and right channel would be about 6 dB for a 1 Meg Ohm input impedancet at low...

I have the following Question regearding the impedance calibration: Which assumption is true? A) Only a single real valued calibration factor is used for the correction. It is extacted from the impedance calibraition file at mid frequncies. B) The complete impedacne calibration file is...
