AB - After 20 years successful operation of SPring-8, the third generation synchrotron radiation facility, maintaining old analogue modules of LLRF system tend to be difficult. Meanwhile a digital technology like FPGA, fast ADC/DAC become popular. We decided to replace the old analog LLRF system with modern MTCA.4 based one. Prior to replacing the system, we planed to examine the performance of the new system at an RF test stand. An AMC digitizer and a RTM vector modulator were introduced. A feedback control function was reproduced in the FPGA of the digitizer. We also adopted EtherCAT for relatively slow control, such as a motor control for cavity tuner and monitoring of a vacuum pressure. In addition to developing the new hardware of MTCA.4, we were developing a new data acquisition system and a new MQTT based messaging system for an integrated control framework of SPring-8 and SACLA, the X-ray free electron laser facility. To prove feasibility of new control system, it was implemented at the RF test stand. As the result of high power RF operation, we achieved demanding stability of RF in the cavity. We also confirmed that new software framework was enough to control LLRF system.
