HP / Agilent 11583C Coaxial Attenuators Set

The HP/Agilent 11583C Coaxial Attenuators Set is a precision fixed-attenuator assembly for RF and microwave signal level control from DC to 26.5 GHz. The set comprises four individual attenuators with discrete values of 3 dB, 6 dB, 10 dB, and 20 dB, each based on the Agilent 8493C platform and equipped with APC-3.5 connectors. Construction uses thin-film-tantalumnitride on sapphire substrate for high-precision performance with resonance-free operation extending to 34 GHz. Each unit includes NIST-traceable calibration documentation specifying attenuation accuracy and reflection coefficient at each port. The set arrives in a walnut accessory case.
