The company roots dates back to the 1950’s, when Pendulum was the Swedish branch of Philips Test & Measurement division. Pendulum Instruments was a spin-off in 1998, and has grown substantially since then, via own development and acquisitions. Pendulum Instruments currently has offices in Poland, Sweden and USA, and we have sales representatives in approximately 100 countries in all continents plus service centers in several countries.
Our Frequency Analyzers, with modulation domain analysis possibility, plus pulsed RF analysis of short radar pulses, have found their way into many of the world’s leading military electronics companies. The main test objects are radio-based equipment in the RF and microwave segment, like communication radios, missile guidance, radar, and navigation equipment. The Modulation Domain analysis gives additional information of the signal under test, compared to traditional oscilloscopes and Spectrum Analyzers, like frequency agile hopping, frequency switching, PLL control loops, short-term stability of oscillators (ADEV), Radar chirp frequency profiling and more.
Our traceable Rubidium frequency standards are used in many national time and frequency metrology labs around the world, as well as in independent calibration labs, and company internal calibration labs. They are low-cost traceable substitutes for Cesium clocks, with near-Cesium stability Our high-end Frequency Counter/Analyzers are also frequent instruments for time and frequency calibration of reference oscillators, and for high-resolution phase-comparison between atomic clocks.
Most of the world’s leading manufacturers of high-end oscillators, from Japan via Asia/Pacific, Russia, Europe to USA, are using the Pendulum Frequency counters in production test systems for maximum test throughput, thanks to the very fast measurement speed combined with high resolution.
Many of the world leading telecom industries use our products, especially manufacturers of wireless network equipment for GSM, 3G, 4G, LTE and 5G. The traceable Frequency standard GPS-89 is a typical in-house frequency reference, normally distributed via optical fiber by our Frequency Distribution Amplifiers to multiple test benches and test systems. When the end products, for example radio base stations, are tested, our Frequency Counter/Analyzers perform various measurements, like time delay between multiple MIMO antenna elements, frequency verification of master oscillator, and more.
Our GNSS Simulators are popular at many of the world’s leading automotive industries, for testing embedded GNSS receivers for navigation, safety (eCall, UN-R144) and more, with built-in test scenarios according to standards. The GNSS simulators are also used for drive test via record-and-replay and are used in advanced multi-test chambers with real-time scenario generation and sensor simulation (inertial sensors), to simulate real time changes of e.g. acceleration, ascending (climbing hills) and skidding. Another use is for simulating the position of autonomous vehicles (driverless), where the differential GNSS and RTK options assist in achieving cm-accuracy in positioning.
The Pendulum products are popular affordable, high-resolution and easy-to use tools in various electronic industries around the world, for example many of the major consumer electronics companies in Japan, world leading contract manufacturers, electronic RF & Microwave component manufacturers (for example radar sensors for speed control), other global test & measurement companies, medical electronics industries, and more. Frequency Counters are used in production as a high-performance, yet affordable, tool for verification of basic time and frequency parameters, with ultimate measurement speed for high throughput. Sometimes our Frequency standards supply the reference frequency to the test system.
