Era Building and Era Creation through "Measuring Technologies"
Anritsu was founded in 1895, the year in which Marconi successfully demonstrated the world's first wireless telegraph. The development of Anritsu has traced the emergence of modern communications, and its history has run concurrent with the evolution of information and communication networks. Now, as a result of the development of a variety of information and communication technologies, a range of services available by way of communication networks are offered. Using the "Measuring Technologies" accumulated over the course of its history of more than 110 years, Anritsu has continued to create and offer a range of original & high-level products and services, to open the door to communications in the 21st century.
