HP 8494A DC to 4 GHz Manual Step Attenuator

Product Summary

The HP 8494A dc to 4 GHz manual 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 890. Custom step attenuator/switch combinations are possible. The HP 11716A/B/C interconnect kits provide quick connection of HP 8494/5/6/7 1 dB and 10 dB step attenuators in series for greater dynamic range with 1 dB steps.

Product Features

• Excellent repeatability (typically 0.01 dB)

• Long life (over five million cycles per section)

• High accuracy (typically ±2%)

• Low SWR (typically less than 1.30)

• Test data available

• 0 to 11 dB in 1 dB steps
