The Keysight (Agilent) 911E Sliding Load is a precision RF and microwave test accessory engineered for network analyzer calibration and high-frequency measurement verification. Its integral 3.5 mm connectors establish a near-perfect airline with minimal discontinuities, reducing reflection artifacts that compromise calibration integrity. The sliding load element exhibits exceptional stability, with reflection coefficient variation below 0.00032 across its full travel range. This enables accurate isolation and characterization of system reflections, making it essential for measuring directional coupler directivity and coaxial slotted line residual SWR.
