SE1022 DSP Lock-In Amplifier

SE1022 Digital Lock-in Amplifier

The SE1022 Digital Lock-in Amplifier provides high-precision phase and magnitude measurements from 1 mHz to 102 kHz. With a high-precision 24-bit ADC and advanced digital signal processing, it reliably recovers weak signals buried in high-noise environments.

Accurate Phase & Magnitude Detection under High Noise

The SE1022 Digital Lock-in Amplifier delivers excellent performance across its 1 mHz to 102 kHz bandwidth. Using the latest digital signal processing technology and a high-precision 24-bit ADC, it can accurately detect the phase and magnitude of weak signals overwhelmed by large noise.

Research-Grade Lock-In with Multi-Harmonic FFT & High SNR

The SE1022 is comparable to leading lock-in amplifier brands and performs even better in parameters such as measurement accuracy, SNR, and dynamic reserve. It also integrates multi-harmonic measurement and FFT functions to meet the needs of scientific research and industrial applications.
