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.

Operating from 75,000 square feet of company-owned facilities in the heart of Silicon Valley, SRS has been designing and manufacturing test instruments for more than 35 years. Their innovative manufacturing process has allowed us to maintain our renowned product quality and to offer quick delivery from stock.

Product innovation has driven the adoption of SRS’s products. Recognised with R&D Innovation Awards, SRS was first to use DSP in lock-in amplifiers, direct digital synthesis in function generators, logarithmic transimpedance amplifiers in RGAs, and rational approximation frequency synthesis in RF signal generators and atomic clocks.

Over the years SRS has continuously invested in product research and development, plant, and equipment. Being privately held, the company has maintained the flexibility to invest where it sees opportunity, allowing good ideas the time needed to come to fruition. The approach has worked remarkably well. SRS has enjoyed steady financial growth and an unbroken record of profitability, with more than 90 % of its ownership held by current employees.

SRS delivers test solutions to academic, government and corporate users worldwide. They also license their technology to other test and measurement companies, accelerating their pathway into challenging new markets.

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.

Within our generator portfolio, we offer a unique combination of design expertise and leading-edge technologies, working with leading strategic partners to solve design challenges throughout the entirety of your project. Our range of generators includes function/arbitrary waveform generators, pulse generators, and signal generators. Explore technology

Function Arbitrary / Waveform Generators

Function/ arbitrary waveform generators (AWG) are among the most important and versatile pieces of electronic test equipment. Our function generators offer the standard signals and features you expect — modulation, sweep, and burst. They also contain features that give you the capabilities and flexibility you need to get your job done fast, no matter how complex. Explore technology

Signal Generators

Our range of signal generators pushes your device within and beyond its limits with unmatched purity and precision. From basic to advanced functionality, each signal generator delivers benchmark performance in its class to address the requirements in the design and manufacture of radio transceivers and their components; and applications ranging from low-frequency navigation signals to cellular mobile radio, millimetre wave radars, and satellite systems. Explore technology

Frequency counters

The frequency counter products in our portfolio serve all of your frequency and time interval measurement needs. Speed, resolution, and accuracy are just a few benefits that our range offers. With unprecedented resolution, you can capture very small frequencies and time changes. Measurement functions include frequency, period time, pulse width, duty cycle, frequency ratio, RPM, phase A/B time interval A/B, event count, and may have an external clock input for maximum stability and accuracy. Explore technology

Scientific instruments

We cover an extensive range of equipment from top-tier manufacturers to bring you a choice of the most reliable products including delay generators, gas analysers, laser diodes, gated Integrators, amplifiers, power supplies, as well as specialist equipment for testing. Explore technology

Digital Delay Generators

Our versatile digital delay/pulse generators provide precisely defined pulses at repetition rates up to 10 MHz. All digital delay generators measure time intervals by counting cycles of a fast clock (typically 100 MHz). Most digital delay generators also have short programmable analog delays to achieve time intervals with finer resolution than the clock period. Explore technology

Gated Integrators

A gated integrator (also called a boxcar integrator or averager) integrates an analytical signal over a fixed time window. In pulsed experiments, the integrator gate is synchronised with the analytical signal by a trigger. Using our gated integrators gives you the reliability and accuracy you need when acquiring and analysing fast signals. Explore technology

Time and frequency instruments

Working with leading strategic partners for time and frequency instruments enables us to bring you access to a high-quality, specialist range of industry-leading solutions for the calibration, measurement, and analysis of time and frequency. Our wide portfolio of test and measurement instruments are dedicated to a wide range of frequency measurements or applications. Explore technology

Distribution amplifiers

In each application, the amplifier is selected to preserve, improve (or minimally degrade) the input signal’s bandwidth, amplitude, pulse shape, phase noise, and jitter characteristics. Whether you have an application for distributing a low noise 10 MHz frequency signal, CMOS level logic pulses, broadband (DC to 100 MHz) analog signals over 50/75 Ω coax cables, or providing a 10 MHz signal at locations as far as a mile from the source, we have the right distribution amplifiers available Explore technology

Frequency counters

Frequency counters are test instruments used to provide very accurate measurements of the frequency of a signal. They are depended on in R&D and in manufacturing for the fastest, most accurate frequency and time interval measurements. The measurement functions include frequency, period time, pulse width, duty cycle, frequency ratio, RPM, phase A/B, time interval A/B, event count and may have an external clock input for maximum stability and accuracy. Explore technology

Frequency standards

Frequency standards generate a fundamental frequency with a high degree of accuracy and precision. They provide exceptionally low phase noise as well as a low jitter output. The low cost together with its extremely low aging will allow you to deploy precision frequency references throughout a facility without the need to install cables or antennas. Explore technology
