Customer Evaluation

The OE1022D dual-channel lock-in amplifier allows for rapid data acquisition and simultaneous measurement of various demodulation frequencies for synchronization.

Weizmann Institute of Science

The OE1022 Lock-in Amplifier offers superior performance and ease of use for scanning tunneling spectroscopy measurements.

Shanghai Jiao Tong University

The OE1022 lock-in amplifier measures signal-to-noise ratios significantly better than instruments of international counterparts.

Skyray Instrument

After testing several brands of lock-in amplifiers on the market, Prof. Steve Mann of the University of Toronto praised the lock-in amplifiers produced by SSI as the best measurement results among all instruments.

University of Toronto

The performance of the OE1022 lock-in amplifier is stable, and its convergence speed and measurement accuracy in small ranges are significantly better than those of a well-known international brand.
