General Information
•
Ruggedness, reliability, and small size make these attenuators useful
both on the bench and in systems applications.
•
Accuracy and low SWRs make the attenuators well suited for extending
the range of sensitive power meters for higher power measurements and
applications such as calibration standards and RF substitution
measurements.
•
Each attenuator is tested with a vector network analyzer for attenuation,
and a plot of actual attenuation values is printed on the label attached to
the body of the attenuator (except for the 8490D/G and 8493C).
Option UK6 calibration data, which is generated by a network analyzer,
provides a tabulated list of attenuations and reflection coefficients in which
the number of frequency points provided depends on the model number and
frequency range. Option UK6 calibration data is available when attenuators
are first purchased and recalibrations are available through Agilent
Technologies Service Centers.
The 11581A, 11582A, and 11583C are boxed sets of four coaxial fixed
attenuators of 3, 6, 10, and 20 dB as shown in
Each attenuator set comes with a printed calibration report that gives the
actual attenuation and reflection coefficient of each port at frequencies from
100 MHz to 12.4 GHz for 11581A, 100 MHz to 18 GHz for 11582A and 100
MHz to 26.5 GHz for 11583C, at increments from 100 to 500 MHz.
