HP 8494H Programmable Step Attenuator, DC to 18 GHz, 0 to 11 dB, 1 dB steps

 

Description

The Keysight 8494H dc to 18 GHz programmable step attenuator offers exceptional repeatability and reliability. Attenuation is provided 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, NIST traceable data (SWR and attenuation) is available as Option UK6. A maximum switching time of 20 ms (including contact settling) speeds automatic testing. Custom step attenuator/switch combinations are possible. The Keysight 11716A/B/C interconnect kits provide quick connection of Keysight 8494/5/6/7 1 dB and 10 dB step attenuators in series for greater dynamic range with 1 dB steps.
