To offer customers with greate application flexibility, Healthyphoton's new HP-MLIA Mini Dual-Channel Modulation Lock-in Amplifier simplifies complexity by integrating core functionality into a more compact lock-in box. With an ultra-compact dimensions of 116×60×26 mm³, it facilitates portability and system integration. Floating-point digital signal processing tasks are accelerated by FPGA hardware. Result acquisition and host computer interaction are handled by an ARM microcontroller. Designed on the principle of independent dual input/output channels, the system implements dual-channel phase-locked applications on a single board.
We wholeheartedly welcome OEM partnerships.

Phase-locked amplifiers are frequently employed in scientific experiments requiring the measurement of minute signals within noisy environments. Where the frequency of the desired signal is known relative to the noise, the instrument can employ a matched reference frequency to “lock” onto and extract the target periodic signal. This significantly reduces the impact of noise, enabling the measurement of extremely faint continuous periodic signals.
