Abstract:
1. A power meter for use with a Bruene-type directional coupler having a voltage output proportional to a power level of a radio frequency signal passing through the coupler, the power meter comprising: a) a coupler input for accepting the voltage output of the Bruene-type directional coupler; b) an analog-to-digital converter having an analog input coupled to the coupler input and a digital output; c) a microprocessor having an input coupled to the digital output of the analog-to-digital converter, a plurality of outputs including at least a display output, and a memory, the memory comprising: d) a display coupled to the display output of the microprocessor; e) the microprocessor being configured such that when a voltage from a Bruene-type directional coupler on the coupler input is converted to a measured digital value in the analog-to-digital converter, the microprocessor is programmed to:
