The invention provides a multipoint voltage and current probe system. A metrology system monitors radio frequency (RF) power at a plurality of locations in a circuit. The system includes a plurality of RF sensors that generate respective analog signals based on electrical properties of the RF power, a multiplexing module that generates an output signal based on the analog signals, and an analysismodule that generates messages based on the output signal. The messages contain information regarding the electrical properties that are sensed by the plurality of RF sensors.
