Synthesizer out-of-lock
WebA phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input signal. There are several different types; the simplest is an electronic circuit consisting of a variable frequency oscillator and a phase detector in a feedback loop.The oscillator's frequency and phase are controlled … WebSynthesizer out-of-lock condition: Troubleshoot Synthesizer: W: FAIL 002: The mode being accessed has an incorrect pattern in the Memory Board EEPROM.
