Page 10: Description
Description Description The Agilent 8495D and 8495K are 50-ohm, dc to 26.5 GHz, 0-70 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. - Page 11 TKP12-100-P-TS-100-AU.
