The contribution will summarise the hardware implemented including a comparison of the hardware transfer functions of the new system and the original system using a coaxial cable plant for the same purpose. Automatic monitoring of the hardware transfer function being prepared for 2021 will be provided in order to periodically check drifts of the system and send corrections to the control of the system. Integration of this monitoring and feedforward system into the CERN controls environment will be shown.
