HP 909 Series
The HP 909 series are fixed low-reflection loads for
terminating a 50 Ω (75 Ω for HP 909E) coaxial system
in its characteristic impedance. Whereas the HP 909A
is designed for general purpose applications, the
HP 909C,D,E,F series are intended for use as
calibration standards. All loads find wide use as
accessories for both broadband and narrowband
measurement instruments, with models covering dc
to 26.5 GHz.

Sliding
HP 911 Series
The HP 911D,E family of sliding loads represents an advance in calibration and verification of network analyzers.
They utilize integral connectors to form a near perfect airline without the discontinuities associated with changeable
connectors, which cause reflections. The load element is highly stable, with a reflection coefficient variation of less
than 0.00032 as the element location is varied, greatly increasing the integrity of a calibration. A locking mechanism
is used to locate and lock the center conductor reference plane to within 0.00005 inch of the outer reference plane.
