Abstract
A method for calibrating an electromagnetic measurement tool includes deploying a test loop about a first antenna in the electromagnetic measurement tool and electromagnetically coupling the test loop and the first antenna and measuring a first voltage. The test loop is then deploying about a second antenna in the electromagnetic measurement tool and electromagnetic ally coupling the test loop and the second antenna and measuring a second voltage. A ratio of the first voltage to the second voltages is computed that can be used to calibrate the first antenna with respect to the second antenna.
