The Keysight 8494B dc to 18 GHz manual step attenuator offers exceptional repeatability and reliability. It provides attenuation in 1-dB steps from 0 to 11 dB. Precision gold-plated leaf springs ensure long life (over 5 million cycles) and very high attenuator repeatability (typically 0.01 dB). To improve measurement accuracy, Option UK6 provides NIST traceable data (SWR and attenuation). Custom step attenuator / switch combinations are possible. Use the The Keysight 11716A / B / C interconnect kits to quickly connect 8494 / 5 / 6 / 7 1-dB and 10-dB step attenuators in series for greater dynamic range with 1-dB steps.
