1. Sensor Head used to measure the characteristics: CX1203A.
2. The slide switch of CX1203A to be set to “0 Ω”.
3. 20 MHz noise bandwidth measured with mainframe.
4. Standalone bandwidth. The effective measurement bandwidth when connected to mainframe can be estimated by the following equation.

1. Accuracy is defined at VCM = 0 V (zero Common Mode input voltage at either +IIN or -IIN). Add 0.9% typical to Offset error for Vcm up to 12 V. “Readings”
means measured data by mainframe. DC measurement condition: 20 ms averaged.
2. After executing the User Calibration with mainframe. Supplemental characteristics.
