Late 1950s

Development of the first line of testing products

By the late 1950s, the company had launched its own comprehensive portfolio of slotted lines for RF applications.

These slotted lines were available in manual and motor-driven coaxial and waveguide versions and naturally accompanied by a wide range of accessories such as detector test heads, selective screen amplifiers, test absorbers, adjustable attenuators, directional couplers, phase shifters, resonant stubs, and tap lines. These products remained available until about two decades later, when slotted lines were superseded by network analyzers.

It’s common knowledge that SPINNER has ranked among the world’s leading makers of passive RF equipment for several decades. But not everyone is aware that the company’s founder, Dr. Georg Spinner, also developed a groundbreaking dual-beam oscillograph at the start of his career, thus paving the way for us to supply test equipment.

Although this product category hasn’t always been the main focus of the company’s sales efforts, it has played a major role. We originally developed many products to meet our own needs, according to the maxim that “only those who accurately test can also ensure optimal product performance.”
