Progressive Modulation Index - Safran CORTEX CRT Quantum User Manual

3.5.11. Progressive modulation index

This feature is available for SPS version E4R32 and higher.
When activated, this feature allows the modulation amplitude (index in PM mode, deviation in FM mode) to be
gradually increased from zero to the requested value, instead of instantly raised from zero to the requested
value.
The modulation increases in 6 steps of 65.536 ms each, resulting in a total time of 393.216 ms to raise from zero
to the nominal amplitude.
The modulation increase follows a geometric law with a ratio of 2 between two steps.
The progressive modulation index feature, when activated, applies to the TCU and RAU signal.
