LBTEK-Digital Lock-in Amplifier

Product Description

DC~1 MHz demodulation frequency
Number of demodulators: 1 dual-phase
Supports Sine and TTL reference signal input and output

Lock-In Amplifier (LIA) is a commonly used instrument for extracting weak signals from noise. It utilizes the cross-correlation detection principle between the signal under test and the reference signal to achieve narrowband processing of the signal, effectively suppressing noise components unrelated to the reference frequency, thereby enabling signal detection and tracking. LBTEK's lock-in amplifiers are based on an advanced programmable logic gate array and embedded system architecture, as well as leading low-noise analog circuits, achieving rich and powerful analog input and output functions. They offer advantages such as strong anti-interference capability, low acquisition noise, large dynamic range, and high temporal stability, and are widely used in fields such as physics, chemistry, biology, materials science, communications, and medicine. The lock-in amplifier supports the installation of more options. For details, please refer to the "Technical Specifications" page.

Digital Lock-in Amplifier

DC~1 MHz demodulation frequency
Dynamic reserve: > 120 dB
Input voltage noise density: < 2.4 nV/√Hz

LBTEK's lock-in amplifier integrates multiple functions such as a visual lock-in amplifier, virtual oscilloscope, parameter scanner, signal generator, and data acquisition. It also supports optional features, allowing the selection of up to 4 demodulators, a PID controller, 5MHz demodulation frequency, FM/AM options, and impedance analysis options to meet more functional requirements. It boasts exceptional noise performance, with a noise voltage as low as 2.4nV/√Hz and an input current noise better than 15fA/√Hz, enabling it to capture weak signals under noisy backgrounds. It provides SDKs in C++, Python, LabVIEW, and MATLAB for user secondary development, facilitating device integration.

Note: Product firmware is continuously upgraded and optimized. After purchase, please contact technical support to obtain the latest firmware version.
