Keysight 8495G DC to 4 GHz Attenuator; 70 dB

The Keysight 8495G Programmable Step Attenuator is a high-performance device designed for precision signal control across a DC to 4 GHz frequency range. Offering 10 dB steps and 110 dB total attenuation, this attenuator provides exceptional repeatability, with a typical variation of 0.01 dB. Its gold-plated leaf springs ensure over 5 million cycles of reliable operation, making it perfect for demanding environments where accuracy and longevity are critical. With fast 20 ms switching time, this attenuator is ideal for automated testing, research, and RF measurements. Additional NIST-traceable data is available for improved measurement accuracy (Option 890).
