Method for determining optimum power amplifier configurations using list mode testing

摘要

A calibration system for calibrating wireless circuitry in an electronic device is provided. The test system may include test equipment, a computer, and a device under test (DUT). The test equipment may measure the output power of the DUT. The DUT may include power amplifier circuitry that is provided with a power supply voltage supplied by power supply circuitry. A list mode sequence of commands may be provided to the DUT and the test equipment to calibrate the power amplifier circuitry. The list of commands may be processed by the DUT to produce radio-frequency signals. The list of commands may be simultaneously processed by the test equipment to perform measurements on the radio-frequency signals. The computer may retrieve measurement data from the test equipment after testing is complete. The computer may subsequently determine calibrated control settings for the DUT that reduce power consumption while ensuring satisfactory adjacent channel leakage performance.

1. A method of calibrating a wireless electronic device, the method comprising:
with computing equipment, providing a message that contains a list of instructions to the wireless electronic device, wherein each instruction in the list includes control settings; with the computing equipment, directing the wireless electronic device to process each instruction in the list of instructions in the message after the wireless electronic device has received the message, wherein each instruction directs the wireless electronic device to transmit radio-frequency signals based on the control settings of that instruction; and with measuring equipment, measuring output power levels of the transmitted radio-frequency signals.
