Our range of derivative free space electromagnetic field sensors is designed for the measurement of fast pulsed fields. Different models are available: for electric field (D-dot) and for magnetic fields (B-dot).
Because those sensors are passive, no external power source is required. Baluns, passive integrators and a mounting kit are proposed as accessories. Free space field sensors might be connected through a fibre optic link to the measurement equipment.

Free Space Field Sensors Mounting Kit
The SFMK mounting kit allows the installation of a montena free field measurement chain on an antenna mast. One sensor with its balun and an optional fibre optic transmitter can be fastened onto the stand. Four M6 & 1/4″ x 20 UNC threads enables the installation on different supports and orientations.
Example of Measurement Setup
A free space derivative electromagnetic field sensor delivers two balanced pulse signals to the balun, which are converted into an unbalanced signal.
To ensure noise-free measurement over long distances, the balun is connected through a fibre optic link to the measurement equipment installed in a shielded enclosure.
Montena PULSELab software application automatically configures the oscilloscope for pulse acquisition, display, and storage in the control PC.
