What is it about?
Low Level Radio Frequency control system (LLRF) is used to feed high power RF to accelerating cavities. In a synchrotron radiation facility, special type of cavity is used where electrical field uniformity is important. But high power RF warms up the cavity and degrades field uniformity. To solve this situation, frequency offset function is added to the LLRF.

Why is it important?
Newly developed LLRF system enables to keep the cavity tuning condition without any mechanical components, with fast time response, and with minimum degradation of the phase and amplitude stabilities.
