Self-calibrating radio frequency calorimeter

A method for making a radio frequency (RF) power measurement using an RF calorimeter, comprising:

• providing an RF calorimeter,
• said RF calorimeter having a measurement accuracy with an uncertainty of less than about ±0.25%,
• said RF calorimeter having a low-frequency reference source integrated into said calorimeter for a purpose of self-calibration;
• wherein said RF calorimeter further comprising a controller, said controller self-calibrates said RF calorimeter on-demand immediately prior to measuring a power value of an RF source having an unknown power;
• said RF calorimeter having a silicon oil as a coolant;
• calibrating said RF calorimeter using said low-frequency reference source;
• and
• measuring said power value of said RF source having said unknown power.

A radio frequency (RF) calorimeter comprising:

• a low-frequency reference source integral to the RF calorimeter for a purpose of self-calibration, said RF calorimeter having a silicon oil as a coolant;
• a controller having a processor and a memory;
• said memory storing executable code when executed by the processor performs actions comprising:
• calibrating said RF calorimeter using said low-frequency reference source on-demand immediately prior to measuring a power value of an RF source having an unknown power;
• and
• measuring said power value of said RF source having said unknown power;
• said RF calorimeter having a measurement accuracy with an uncertainty of less than about ±0.25%.
