Lock in amplifier (SR830)

The Lock-In Amplifier (SR830) from Stanford Research Systems is a high-precision instrument designed to recover weak AC signals obscured by noise sources up to 100,000 times larger. Utilizing advanced Digital Signal Processing (DSP) to replace traditional analog demodulators, it offers completely drift-free performance with a dynamic reserve greater than 100 dB. Key features include a frequency range of 1 mHz to 102 kHz, simultaneous display of magnitude and phase, 0.01° phase resolution, and synthesized reference sources, making it an essential tool for optical, electrical, and materials science applications
