Wireless device test station calibration

摘要

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.

1. A portable radiofrequency (RF) test station calibration device, comprising:
an RF power meter; a power sensor configured to connect to an RF test instrument of a wireless device RF test station through a calibration board, the RF test instrument being configured to test and calibrate one or more other RF devices under test; and a computing device configured to connect to the RF test instrument and to the RF power meter, the computing device comprising a logic subsystem and a storage subsystem, the storage subsystem storing instructions executable by the logic subsystem to:
control the RF test instrument to transmit one or more RF signals having requested transmission values to the power sensor, the one or more RF signals being transmitted to the power sensor through each of a first path and a second path independently,wherein the first path extends from the RF test instrument to a first RF test instrument connector of the calibration board, to a first power sensor connector of the calibration board and to the power sensor, and the second path extends from the RF test instrument to a second RF test instrument connector of the calibration board, to a second power sensor connector of the calibration board and to the power sensor; and, for each of the first path and the second path,
receive measured transmission values from the RF power meter, the measured transmission values measured from the RF signals received at the power sensor;determine a difference between the requested transmission values and the measured transmission values; andsend 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.
