Lock-In Amplifiers
4 used models available from Stanford Research Systems · Buy, Rent, Sell, Repair
Lock-in amplifiers pull periodic signals out of noise by demodulating them against a reference frequency, recovering amplitude and phase that direct measurement would miss. Options range from analog units like the SR510 to dual-phase DSP models such as the SR830 and SR850, covering frequencies to 100 kHz, plus low-noise preamplifiers like the SR560. These instruments support spectroscopy, photonics, and quantum computing research.
