Description
The Stanford Research SR844 Lock-In Amplifier is an advanced and versatile instrument widely used in scientific research and engineering applications. This amplifier is specifically designed to accurately measure low-level signals that are often obscured by noise or interference. It achieves this by utilizing a technique known as synchronous detection, where the desired signal is modulated with a reference signal and then demodulated to extract the necessary information. The SR844 offers exceptional sensitivity, with a dynamic reserve of up to 130 dB, enabling it to detect signals as small as a few nanovolts. Additionally, it has a broad frequency range spanning from 1 mHz to 200 kHz, allowing for measurements across various fields like optics, physics, and materials science. With its user-friendly interface and robust signal processing capabilities, the SR844 Lock-In Amplifier is an essential tool for researchers seeking precise measurements and accurate data analysis.
