B-DOT AND D-DOT FIELD SENSORS
Your Swiss-engineered essential tools for precise, real-time measurement of fast electric or magnetic field transients. Perfect for high-power electromagnetic immunity testing.
Real-time measurement of electromagnetic transients
Up to 10 GHZ bandwidth
Complete solution from one single source
B-Dot and D-Dot field sensors are small derivative monopole or dipole antennas. They deliver an output signal proportional to the variation of electromagnetic field strength. They are the perfect solution for real-time measurement of fast electric or magnetic field transients, particularly in relation with high-power electromagnetic immunity tests.
Ground plane sensors are monopole antennas, whereas free space sensors are dipole antennas. The latter shall be connected to a balun combining the signals from both antenna arms to one single output connector.
The output electrical signal shall be integrated to recover the measured electromagnetic transient. This can be done by one of the passive integrators Montena has developed or by means of a mathematical integration.
To simplify your process, we recommend our PULSELab software application. It has been specifically designed to ease the measurement of electromagnetic transients with derivative sensors. We also strongly advise you to opt for our fiber-optic links to avoid interferences during measurements.

FAQ
What are B-Dot and D-Dot field sensors?
B-Dot and D-Dot sensors are compact monopole or dipole antennas that deliver output signals proportional to the time derivative of electric or magnetic field strength, used for precise real-time measurement of fast electromagnetic transients.
What applications are these sensors used for?
They are ideal for high-power electromagnetic immunity testing, providing accurate transient field measurements.
What types of sensors are available?
Ground plane sensors are monopole antennas, while free-space sensors are dipole antennas, which require a balun to combine signals into a single output.
How is the output signal processed?
The output signal requires integration to obtain the actual transient field waveform, achievable using Montena’s passive integrators or mathematical integration.
What software does Montena recommend for processing sensor data?
Montena recommends the PULSELab software, designed to simplify measurement and analysis of electromagnetic transients with these sensors.
How can I avoid measurement interference?
Montena suggests using fiber-optic transmission links to maintain signal integrity and avoid electromagnetic interference during measurements.
Where can I find detailed technical information?
Datasheets and documentation are available on Montena’s website, along with expert support services.
