step attenuators

Test and measurement tool manufacturer Rohde & Schwarz has recently unveiled their latest RSC family of switchable, mechanical step attenuators. The company's latest product covers frequencies from DC to 67GHz and includes a precision model with 0.1-dB step size for enhanced accuracy and stability. The instruments also 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 6GHz. The other two units offer an attenuation range of 0 to 139.9 dB with a 0.1-dB step size from DC to 6GHz and 0 to 115 dB with a 5-dB step size from DC to 18GHz.

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

The datasheet for the RSC step attenuator can be found here.
