RF SIGNAL ALIGNMENT CALIBRATION

摘要

A method is provided for aligning RF signals of a first channel bank and additional channel banks in a test platform. A plurality of correlators is used to correlate a reference code signal carrying a particular code at a particular chip rate with a received code signal carrying the particular code at the particular chip rate from the first channel bank to establish a first timing offset. The plurality of correlators is used to correlate a continuation of the reference code signal with additional received code signals carrying the particular code at the particular chip rate from the additional channel banks to establish additional timing offsets. The first timing offset and additional timing offsets are applied to the first and additional channel banks. The plurality of correlators includes at least 12 correlators, and a timing offset is established in a correlation interval having a shorter duration than the particular code.

1. A method of aligning RF signals of a first channel bank and one or more additional channel banks in a test platform, comprising:
using a plurality of correlators to correlate a reference code signal carrying a particular code at a particular chip rate with a received code signal carrying the particular code at the particular chip rate from the first channel bank to establish a first timing offset; using the plurality of correlators to correlate a continuation of the reference code signal with additional received code signals carrying the particular code at the particular chip rate from the additional channel banks to establish additional timing offsets; and applying the first timing offset to the first channel bank, and the additional timing offsets to the additional channel banks, to align the first channel bank and the additional channel banks, wherein the plurality of correlators includes at least 12 correlators.
