SE2022 DSP Lock-In Amplifier (Dual-channel)

♦ High-Precision Signal Extraction in Noise

The SE2022 dual-channel lock-in amplifier is the latest core technology product with excellent high performance and broadband measurement capabilities. Based on digital modulation technology, the instrument is equipped with a 24-bit high-precision analog-to-digital converter (ADC) and a 16-bit high-speed analog-to-digital converter (DAC). With the newly launched stream architecture, it can accurately, quickly and flexibly detect effective signal components hidden in strong noise.

♦ Multi‑Function Dual‑Channel Precision Analyzer

SE2022 has two independent and synchronous input channels, which can not only measure the amplitude and phase information of two input signals at the same time, but also reach the international leading level in key performance indicators such as measurement accuracy, operating frequency range, signal-to-noise ratio and dynamic reserve. In addition, the newly added multi-harmonic measurement, oscilloscope and spectrum analyzer functions, and PID control functions make SE2022 widely applicable to various needs in scientific research and industrial fields.
