Interference Calibration
This calibration is used to adjust the amplitude of the common mode
interference signal depending on the signal frequency.
The data generator sets to '0' V the DC signal. Then, a sweep of the
sinusoidal interference signal is done, starting with the Min Interference
Value and is increased using the Step Size until the Max Interference Value
is reached. Because of the low pass filter behavior of the signal, the
voltage depends on the frequency of the interference signal. Therefore, the
voltages are calibrated over a Frequency Range. At each step, the
oscilloscope measures the common mode interference amplitude and then
the set and the actual amplitude value are stored.
