Common Mode Interference Calibration
Purpose and Method
This procedure calibrates the Common Mode Interference (CMI) at TP1.
For this purpose, use a real-time scope. The test automation starts by
applying small common mode interference amplitudes and increases the
amplitude levels. For every set CMI value, the corresponding amplitude is
measured.
This calibration is only available for HBR3 data rates.
