Hewlett-Packard step attenuators offer exceptional repeatability and reliability in a wide range of attenuation, frequency, and connector options. Each attenuator contains three or four cascaded attenuator sections; edge-line contacts insert and remove attenuator sections as needed. Precision gold-plated leaf springs ensure long life and very high attenuator repeatability. Programmable models feature fast-switching solenoids and attenuation programming is done through a 12-pin connector.
To improve measurement accuracy in manual and automated test systems,
NIST traceable data (SWR and attenuation) is available as Option 890.
Generated on an HP 8510 network analyzer, this option offers swept data
for each attenuator in 250 MHz steps from 1500 MHz to 26.5 GHz,
depending on the model.
