In the 120 years since its establishment, Anritsu has been the starting point of many kinds of wireless and wired communication devices. We have achieved this through a constant cycle of figuring out what people needed in each new age and creating new technology out of existing technology. Our measuring instruments are a symbolic example of this. Measuring instruments are high-tech devices for measuring signals and radio waves, and are essential in the development and production of communication devices. Anritsu began producing its own measuring instruments in-house to evaluate its wired and wireless communication devices. Our management saw a greater scope of potential and began commercializing these instruments, and signal generators, electric field strength meters and other instruments were launched. A particularly successful example is our measuring instruments for microwave circuits. Microwave circuits were a key part of a plan by Nippon Telegraph and Telephone Public Corporation (now NTT, one of Japan’s largest phone companies) to expand Japan’s telegraph and telephone services after World War II, and our measuring instruments played an important role in this initiative. We cemented our position in the test and measurement industry through overseas expansion of our business in measuring instruments for microwave circuits, including business from AT&T, the largest telecommunications company in the US. Since then, we have continued to play a part in the advancement and development of our information and communication-based society by creating measuring instruments that are the de facto standard in fields such as fiber optics, digital communication and mobile communication.
