| Once both cavities are tuned on resonance, it's time to configure the vector sum signal. Cavity vector sum signal is calculated in real time by LLRF9 FPGA and is compared to the cavity setpoint in the closed loop operation to generate the feedback loop error signal. The error signal is amplified by proportional and integral loops to derive appropriate klystron/ | Once both cavities are tuned on resonance, it's time to configure the vector sum signal.

| Probe signals from two cavities pass through digital gain/phase blocks before being summed together. Gain/phase block can be used to apply arbitrary phase shift and attenuation to the probe signal. | Probe signals from two cavities pass through digital gain/phase blocks before being summed together.
