Programmable Attenuator Products

Programmable phase shifters blue Consider how many devices each of us uses every day. Our laptop, smartphone, tablet, and for some of us, a smartwatch, earbuds, plus all the connected devices in our home: thermostat, lights, doorbells, webcams, even our televisions. Now multiply this by billions, all connected to the Internet.

Spectrum Control’s programmable attenuators make this possible by helping companies automate testing and simulate real-world conditions in the lab. This ensures your newest router, smart device, chipset, wireless service or application will all function as advertised, and rollout will take place on time, for less cost than through manual testing.

Our line-up of programmable attenuators includes both our solid-state and electromechanical programmable attenuators and our line of multi-channel programmable attenuator subsystems. Each offers an extensive range of performance options and configurations to choose from, while maintaining standard programming commands and control interfaces – for ease of use.

Programmable attenuators for transmission loss simulation, signal fading, and handovers; available in a variety of step sizes and frequency bands. High attenuation ranges with low step resolutions.
