Available Configurations

The 8495G DC to 4GHz programmable step attenuator offers exceptional repeatability and reliability. Attenuation is provided in 10dB steps from 0 to 70dB. 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.

  • Frequency range: DC to 4GHz

  • Maximum SWR: 1.35
  • Repeatability life: 0.03dB max 5 million cycles per section, typical
  • 5 million cycles per section
  • Maximum RF input power: 1W (average), 100W (peak)
  • Connector type: choice of type-N female, SMA female, APC-7
  • Programming connector: 12-pin Viking, optional 14-pin DIP
