HP/Agilent 11940A Close Field Probe Description

The Agilent 11940A is a hand-held probe specially designed to measure magnetic field radiation from surface currents, slots, cable, and ICs for EMC diagnostic and troubleshooting measurements. Its unique design results in a high level of electric field rejection. This significantly reduces errors allowing calibrated and repeatable measurements. Each probe is calibrated and comes with a two-meter, RG-223 coaxial cable, an SMA (f) to Type-N (m) adapter, and an SMA (f) to BNC (m) adapter.
