Embodiments for calibrating a radiofrequency (RF) test station with a portable RF test station calibration device are disclosed. In one example, a portable RF test station calibration device comprises an RF power meter, a power sensor, and a computing device. The computing device may be configured to connect to the RF test instrument and to the RF power meter. The computing device may further comprise instructions executable by a logic subsystem to control the RF test instrument to transmit one or more RF signals having requested transmission values, receive measured transmission values from the RF power meter, determine a difference between the requested transmission values and the measured transmission values, and send a calibration value to the RF test instrument to be stored at the RF test instrument, the calibration value derived from the difference between the requested transmission values and the measured transmission values.
