The Mod. N858 is a double attenuator housed in a one a one unit wide NIM module. The module does not require any power supply since it is made up of resistive cells. Attenuation ranges from 0 to 44.5 dB for each section (0.5 dB steps). Each section is provided with two LEMO 00 connectors, one for the input (50 Ω impedance) and one for the output, and seven toggle switches for attenuation setting.
