      abstract     = {In the paper we are presenting universal solution for RF
                      and laser cavities regulation including piezo controls based
                      on MTCA.4 electronics. The RF field control electronics
                      consists of RTM for cavity probes sensing and high voltage
                      power source driving, AMC for fast data processing and
                      digital feedback operation. The piezo control system has
                      been setup with high voltage RTM Piezo driver and low cost
                      AMC based FMC carrier. The laser cavity electronics uses the
                      same hardware setup. The laser RF signal is a product of
                      analog down conversion to intermediate frequency of nth
                      harmonic of the laser repetition rate which is one above the
                      reference frequency the laser needs to be locked. The fine
                      tuning of the laser is carried out using cavity fiber
                      stretcher. The coarse tuning of the supported optics is done
                      using piezo motor driver application. The both channels can
                      be operated using digital feedback controllers. The
                      communication between AMC modules is performed using low
                      latency link over the AMC backplane with data throughput up
                      to the 3.125 Gbps. First results from CW operation of the RF
                      field controller and the cavity active resonance control
                      with the piezo tuners are demonstrated. The laser lock
                      application performance using both fine and coarse channel
                      feedbacks is shown and briefly discussed.},
