METHOD AND SYSTEM TO ENHANCE ACCURACY AND RESOLUTION OF SYSTEM INTEGRATED SCOPE USING CALIBRATION DATA

摘要

This specification discloses methods and systems for implementing a chip integrated scope (i.e., chip scope (CS)), which is a feature that allows a user to scope RF signals (internally and externally to the DUT (device under test)), by using the RF receive path (including amplifier, filter, ADC, DSP) to capture and store signal traces. In some embodiments, this specification discloses methods and systems to enhance the resolution and accuracy of these signal traces by using raw and correction data for gain/phase compensation of gain/phase impairments introduced in the Rx (receiver) path. In some embodiments, the correction data is generated from one or more of the following: simulation data, characterization data, production test data
