ABSTRACT:
Methods and apparatuses for testing a calibrated VCO to determine whether the VCO has adequate fine frequency tuning capability. A range of coarse frequency tuning calibration settings are determined from coarse frequency tuning calibration settings obtained during a coarse frequency tuning calibration process. A determination is then made as to whether a fine frequency tuning capability of the VCO is adequate based on the determined range of coarse frequency tuning calibration settings.
