R&S step attenuators reach 67 GHz

-January 30, 2013

Rohde & Schwarz has launched the RSC family of switchable, mechanical step attenuators, which covers frequencies from DC to 67 GHz and includes a precision model with 0.1-dB step size for enhanced accuracy and stability. In addition, the instruments allow engineers to attenuate signal power step-by-step either manually or by remote control.

The RSC family comprises a base unit with or without an internal step attenuator and a choice of two external step attenuators. Every base unit can control up to four external step attenuators in parallel. The frequency response of each step attenuator is measured in the factory and stored in the instrument to achieve high attenuation accuracy.

Internal step attenuators come in three versions. The standard version has an attenuation range of 0 to 139 dB with a 1-dB step size up to 6 GHz. The other two units offer an attenuation range of 0 to 139.9 dB with a 0.1-dB step size from DC to 6 GHz and 0 to 115 dB with a 5-dB step size from DC to 18 GHz.

External step attenuators provide an attenuation range of 0 to 75 dB with a 5-dB step size from DC to 40 GHz and 0 to 75 dB with a 5-dB step size from DC to 67 GHz.
