Patent ID: 8422966

Claim:
A transmission power calibrating method for use in a to-be-tested wireless apparatus, the method comprising the steps of: controlling, at a computer host, the to-be-tested wireless apparatus to be tested at a plurality of channels and a plurality of gains, and establishing a simplified transmission power calibration table according to a plurality of transmission power values measured by a power meter from the to-be-tested wireless apparatus; comparing the simplified transmission power calibration table with each one of a plurality of complete transmission power calibration tables in a database; detecting a match between a first complete transmission power calibration table in the database and the simplified transmission power calibration table; obtaining, when the match is detected, a mapping table by processing the first complete transmission power calibration table and storing the mapping table in a memory of the to-be-tested wireless apparatus; and controlling, when the match is not detected, the to-be-tested wireless apparatus by the computer host to establish a second complete transmission power calibration table, to obtain the mapping table by processing the second complete transmission power calibration table, and to store the mapping table in the memory of the to-be-tested wireless apparatus, wherein, in the step of controlling and establishing, the channels and the gains for testing are determined from a frequency band defined in one of the complete transmission power calibration tables, and the simplified transmission power calibration table is established by using the determined channels and gains; wherein, in the step of detecting, it is determined whether each measured transmission power value of the simplified transmission power calibration table corresponds to a difference within an error range, and the match is detected when each measured transmission power value corresponds to the difference within the error range.
