Superior RF Performance
•Frequency range: dc to 18 GHz
•Insertion loss at 0 dB: 0.6 dB + 0.09 dB/GHz
•Maximum SWR: 1.5 to 8 GHz, 1.6 to 12.4 GHz, 1.9 to 18 GHz
Repeatability and Life Span
•Repeatability life: 0.03 dB max 5 million cycles per section, typical
•5 million cycles per section
Power handling
•Maximum RF input power: 1 W (average), 100 W (peak)
Features
•Connector type: choice of Type-N female, SMA female, APC-7
•Programming connector: 12-pin Viking, optional 14-pin DIP
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.
