The 8494G DC to 4GHz programmable step attenuator offers exceptional repeatability and reliability. Attenuation is provided in 1dB steps from 0 to 11dB. Precision gold-plated leaf springs ensure long-life (over 5 million cycles) and very high attenuator repeatability (typically 0.01dB).
To improve measurement accuracy, NIST traceable data (SWR and attenuation) is available as Option UK6. A maximum switching time of 20ms (including contact settling) speeds automatic testing. Custom step attenuator/switch combinations are possible.
