Product overview
The ALock series is a multipurpose re-configurable PLL-based platform that is suitable for various phase locking applications in the optical and radio frequency domains (up to 2.8 GHz).
• Modular architecture ensures configuration flexibility of the phase locking system
• Implementation of all-analogue locking module provides precision tuning with exceptional ratio of tuning bandwidth vs. dynamic range
• Digital control enables automatic phase locking procedure and preset storage functions for fast and easy switching between different configurations of the system
• Two independent control signal conditioning channels ensure locking restoration after significant phase fluctuations by quickly switching to a reserve channel with a large permitted phase angle deviation
• Input modules accept a wide range of input frequencies and amplitude levels
• Broad choice of locking driver modules enables various adjustment techniques, from precise digital temperature control to fast modulation via electro-optic modulators
• The implemented high-voltage driver is compatible with high-capacitance piezo actuators having broad modulation bandwidth of up to 200 kHz
