# 16454A Keysight Fixture New

Features:

-   Frequency:  
    1 kHz to 1 GHz
-   Sample Size (Toroids Only):  
    height: ≤ 8.5 mm  
    inner diameter: ≥ 3.1 mm  
    outer diameter: ≤ 20 mm

The 16454A is designed for accurate permeability measurements of toroidal-shaped magnetic materials. Since the construction of this fixture creates one turn around the toroid (with no magnetic flux leakage), the need of winding a wire around the toroid is unnecessary. Complex permeability is calculated from the inductance with and without the toroid. When the E4991A/4291B with option 002 is used as the measurement instrument, direct readouts of complex permeability are possible. In addition, it is furnished with a small and a large fixture to adapt to a wide range of sizes.
