Product Details

Mini dual channel modulation, demodulation, phase-locked amplification module

Lock in amplifiers are often used in scientific experiments that require measuring small signals in noisy environments. Compared to noise, if the frequency of the desired signal is known, the instrument can use a matched reference frequency to "lock" and extract the periodic signal of the target. This greatly reduces the impact of noise and enables the measurement of very weak continuous periodic signals.

Product advantages
• Can demodulate weak signals as low as 10nV with a center frequency of 500kHz;
Two modulation output terminals, with independently adjustable output signal frequency, amplitude, and bias;
Add two sets of triangular wave synchronization signal outputs;
Small size and light weight, easy to carry and integrate with systems;
FPGA algorithms can be flexibly customized according to user needs.
