Leading innovation in research test equipment
Stanford Research Systems (SRS) designs and manufactures high-performance scientific and test instrumentation for researchers, engineers and laboratories worldwide. Based in Silicon Valley, SRS has been developing specialist measurement solutions since the early 1980s, with a strong focus on precision, reliability and practical innovation.
Their portfolio spans a broad range of applications, including lock-in amplifiers, signal and function generators, frequency counters and standards, digital delay generators, photon counters, pre-amplifiers, laser diode controllers and other specialist scientific instruments. These instruments are designed to help researchers generate, control and measure signals with exceptional accuracy — including applications where extremely small signals must be recovered from significant background noise.

About Stanford Research Systems:
Stanford Research Systems (SRS) designs, manufactures, and supports a remarkable range of test instruments for research and industry. Since the early 1980s, SRS has delivered hundreds of thousands of instruments to scientists and engineers all around the world.
SRS products are used in many diverse fields of research. Their lock-in amplifiers recover nanovolt signals from noisy backgrounds. Their atomic clocks have 1 x 10-11 frequency accuracy. Their mass spectrometers measure residual vacuums down to 10-14 Torr. Their RF signal generators, digital delay generators and clock synthesisers provide the most accurate, most precise, and most stable frequency and timing signals available.
Recently, SRS and NASA worked together to adapt the SRS RGA100 quadrupole mass spectrometer for operation in the vacuum of space. The instrument, being unwrapped by astronaut Kate Rubins, was held at the end of the ISS robot arm. By moving the device around suspect areas outside of the Space Station, NASA was able identify the source of ammonia leaks from heat exchangers.
We work with technology partners that combine specialist expertise with a strong track record of delivering dependable solutions for demanding research environments. SRS is a natural fit.
Their products are particularly well suited to applications where precision, low noise, stability and measurement performance are critical. From detecting weak optical or electrical signals to providing highly accurate timing and frequency references, SRS instrumentation can form an important part of sophisticated experimental setups.
Our partnership brings together SRS’s specialist instrumentation with Acal BFi’s application expertise and local technical support. This means we can help customers identify the right SRS solution for their experiment, integrate it with other components and technologies, and provide support throughout the project.
