HP 8490X High-Performance Programmable Step Attenuator Family |
The HP 8490X family of programmable step attenuators offers unmatched
attenuation performance to 40 GHz. The K models provide superior
accuracy and reliability to 26.5 GHz, while the L models offer
unparalleled performance to 40 GHz. The HP 8490X family offers the
selection, performance, and reliability expected from HP attenuators:
attenuation range of 11, 70, or 90 dB; 1 dB and 10 dB step sizes; 5
million cycles per section; better than 0.03 dB repeatability; connector
size options; and the choice of male (plug) or female (jack) connectors.
Connector choices include precision 3.5 mm or 2.92 mm on the K models,
and precision 2.4 mm or 2.92 mm on the L models. While the 2.92 mm
connector format is compatible with both 3.5 mm and SMA connectors,
Hewlett-Packard recommends the more rugged 2.4-mm and 3.5-mm connectors.
