RFCalSys is a multi-port power meter that supports LLRF signals calibration.
RFCalSys is a 16-channel power meter that is calibrated for 500MHz signals. The sensor is a low-noise and broadband power detector from Mini-Circuits. In addition, it has a Beagle Bone Black that works as a digitizer for the DC signal from the sensors and EPICS IOC (Input/Output Controller) server to provide these measurements for high-level application through PVs (Process Variables). It includes a +5V DC power supply. The simplified diagram with the main components and ports is shown in Fig. 1.
