Stanford Research Systems(SRS)

SRS designs, manufactures, and supports a remarkable range of scientific and industrial test instruments. Since the early 1980s, SRS has delivered hundreds of thousands of instruments to scientists and engineers around the world.

SRS products are used in a wide variety of research fields:

Our lock‑in amplifiers recover nanovolt‑level signals from noisy backgrounds.
Our atomic clocks achieve frequency accuracy of 1×10⁻¹¹.
Our mass spectrometers measure residual vacuum pressures as low as 10⁻¹⁴ Torr.
Our RF signal generators, digital delay generators, and clock synthesizers provide some of the most accurate, precise, and stable frequency and timing signals available on the market today.

Headquartered in the heart of Silicon Valley, SRS operates from a 75,000‑square‑foot facility, where it has been designing and manufacturing test instruments for over 35 years. Our innovative manufacturing processes not only maintain the exceptional product quality for which we are known, but also enable rapid shipment from stock.

Product innovation has been the driving force behind the widespread adoption of SRS instruments. SRS has received R&D innovation awards and pioneered numerous industry firsts: the first to use digital signal processing (DSP) in lock‑in amplifiers, direct digital synthesis (DDS) in function generators, logarithmic transimpedance amplifiers in residual gas analyzers (RGAs), and rational approximation frequency synthesis in RF signal generators and atomic clocks.

Over the years, SRS has continuously invested in product development, facilities, and equipment. As a privately held company, SRS maintains a flexible investment strategy that allows it to seize opportunities and give promising ideas the time they need to mature. This approach has proven highly successful: SRS has achieved steady financial growth and sustained profitability, with over 90% of the company's shares held by current employees.

SRS provides test solutions to academic, government, and industrial customers worldwide. At the same time, we license our technology to other test and measurement companies, helping them accelerate entry into challenging new markets.

Recently, SRS collaborated with NASA to adapt the SRS RGA100 quadrupole mass spectrometer for operation in the vacuum environment of space. In the accompanying image, astronaut Kate Rubins is shown disassembling the instrument, which was mounted on the end of the robotic arm of the International Space Station (ISS). By moving the device to suspect areas outside the station, NASA successfully identified the source of an ammonia leak in the heat exchanger.
