Photo of Attenuators

The Attenuators family provides precision passive signal attenuation for analog front-end and test setups, ensuring accurate level matching and protection of sensitive electronics. Implemented with resistive networks and requiring no power supply, these modules offer high-bandwidth performance, low insertion loss, and fine attenuation control in 0.5 dB steps.

Available in both VME and NIM form factors, they enable flexible integration into laboratory and detector systems, with single or dual sections that can be used independently or cascaded for extended attenuation ranges. Designed for 50 Ω environments and fast signal paths, these attenuators maintain signal integrity while allowing precise amplitude adjustment across a wide dynamic range.

  • Passive high-bandwidth attenuators with 0.5 dB step resolution

  • Single or dual sections with wide attenuation range and low insertion loss

  • Available in NIM and VME formats for flexible lab and DAQ integration
