1. A metrology system for monitoring radio frequency (RF) power at a plurality of locations in a circuit, comprising:
- a plurality of RF sensors that each generates a pair of analog signals based on electrical properties of the RF power at one of the locations in the circuit;
a first multiplexer that receives one of the analog signals from each pair of analog signals and routes one of the received signals to an output of the first multiplexer in accordance with a control signal;
a second multiplexer that receives the other one of the analog signals from each pair of analog signals and routes one of the received signals to an output of the second multiplexer in accordance with the control signal; and
an analysis module that generates messages based on the signals from the output of the first and second multiplexers, wherein the messages contain information regarding the electrical properties that are sensed by the plurality of sense channels.
