The Keysight 84904L & 84904M programmable step attenuators offers coaxial measurements to 40 GHz in a compact, rugged design. It offers repeatability of better than 0.03 dB, excellent life (greater than 5 million switching cycles per section) and an attenuation range of 0 to 11 dB in 1-dB steps. High attenuation accuracy and low SWR are achieved through the use of miniature thin-film attenuation.
