The CAEN Mod. V859 is a passive dual section attenuator housed in a 1-unit VME 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). The two section can be “cascaded” in order to obtain a single section featuring a 0÷89 dB (step: 0.5 dB) attenuation.
Each section is provided with two LEMO-00 connectors, one for the input (50 Ω impedance) and one for the output, and seven toggle switch for attenuation setting; an additional switch allows to cascade the two sections.
