What’s the difference between a current probe and an I-dot sensor ?
Current probe vs. I-DOT sensor
A current probe is not really a current sensor, because it does not respond to direct current. A current probe is designed to sense and integrate the first derivative of the current – or, more precisely, the magnetic field associated with the current being measured. Continue reading

Aircraft EMC testing with Fibre Optic Links – part 4: Practical aspects to consider
The requirements of a FOL system vary depending on whether low or high level testing is being conducted. For example, when conducting LLSC/LLSF measurements on an aircraft immersed in a low-level field, very low levels of current or voltage are … Continue reading
Aircraft EMC testing with Fibre Optic Links – part 3: Lightning Testing
Lightning Testing Aircraft lightning testing is concerned with two aspects of the direct attachment of lightning to the aircraft: Direct damage, including fuel explosion Induced electrical transients causing upset or damage to critical electronic systems, known as indirect effects. Direct … Continue reading
Aircraft EMC testing with Fibre Optic Links – part 2: HIRF Testing
HIRF Test Methodology The final stage of aircraft clearance may involve limited illumination of the aircraft with threat level RF fields, typically over the range 10 kHz – 18 GHz. As an alternative approach, with lower facility costs than for … Continue reading
