Abstract:
Various methods provide for trimming the gain in a dual-port phase-locked loop (PLL) of a radio transceiver. Use is made of the radio's demodulator to perform modulation accuracy measurements, thereby reducing the cost and complexity of external test equipment.

Claim (Index 11):
A transceiver of a radio, comprising:\n a demodulator; a dual-port frequency modulator; a phase-locked loop, where a signal generated by the phase-locked loop is modulated to generate a modulated signal from the phase-locked loop; and a processor coupled to the demodulator and the modulator, the processor operable to receive from the demodulator a modulation accuracy indicator and to control the phase-locked loop; where the modulator modulates in accordance with a test data pattern a signal generated by the phase-locked loop of the transceiver to generate a modulated signal, where the test data pattern is automatically generated by an automatic data generation function of the dual-port frequency modulation modulator, the transceiver generates a modulated intermediate frequency signal from a radio frequency (RF) signal and the modulated signal, the demodulator processes the modulated intermediate frequency signal to determine modulation accuracy of the modulated intermediate frequency signal; the processor monitors the determined modulation accuracy of the modulated intermediate frequency signal and responsive to the determined modulation accuracy falling outside an acceptable range of modulation accuracy, the processor adjusts the analog gain value of the transceiver to bring the modulation accuracy of the modulated intermediate frequency signal within the acceptable range of modulation accuracy, responsive to the dual-port FM modulator receiving a data configure signal to select the test data pattern automatically generated by the automatic data generation function and to not select a data pattern provided to the dual-port FM modulator, the automatic data generation function provides to a pulse shape filter of the dual-port FM modulator the automatically generated test data pattern and the pulse shape filter shares the received automatically generated test data pattern, and the phase-locked loop receives the pulse-shaped automatically generated test data pattern.
