♦ Introduction：

• Saluki’s SE1022, SE2011, and SE2021 are general-purpose, high-precision, low-noise input models designed specifically for scientific research.
• Saluki’s SE1022D, SE2012, and SE2022 are dual-channel input models featuring high-precision, low-noise signal detection capabilities across two channels.

In addition, we offer the compact SE1201 and the modular SE1300 and SE1354 models to meet the requirements of various application scenarios. The aforementioned series are low-to-medium frequency lock-in amplifiers, whereas the SE2031, SE2041, and SE2052 (dual-channel) are medium-to-high frequency models capable of operating at frequencies up to 400 MHz. When performing measurements at lower frequencies (e.g., 2 kHz), using a low-frequency lock-in amplifier is recommended to achieve a higher signal-to-noise ratio.
