プログラマブル・ステップ・アッテネータ,DC-26.5 GHz,0-70 dB
The Keysight 8495D and 8495K are 50- ohm, dc to 26.5 GHz, 0 dB to 70 dB (in 10 dB steps), coaxial attenuators with APC 3.5 connectors. Each attenuator is made up of four attenuation sections connected in cascade. Each section consists of a precision thin- film attenuator card, a lossless thru- line, and a ganged pair of edge line transmission lines. The edge lines are flexed to make contact with either the attenuator card or the thru- line. The edge line contacts are gold- plated leaf springs which ensure long life and high repeatability. In the 8495D, the edge line controls are flexed by low- torque cams. In the 8495K, the edge line controls are flexed by solenoid plungers.
