Calibration of field strength probesCalibration is an important tool for ensuring quality and determining uncertainty in final measurements. The basis of this process consists of continuous calibration at RISE.
Calibration of different probes
We offer calibration of numerous types of probe, including electric field alarm probes, ENV 50166-1-compliant alarm probes, three-axis broadband electric field probes and three-axis broadband magnetic field probes.
Probes used in EMC tests must be calibrated with reference to a national standard. RISE (before SP) is Sweden's National Metrology Centre for correction factors for field strength probes.
Methods for electric fields
RISE calibrates correction factors for field strength probes in the frequency range 10 kHz–18 GHz. We generate electric fields of up to 100 V/m or equivalent power density up to 25 W/m2.
Within the interval 10 kHz–1 GHz we use two different TEM cells to create traceability.
Within the interval 1 GHz–18 GHz we carry out calibrations in our anechoic chamber “Hertz” using fields generated from standard gain horns with traceable antenna gain.
Methods for magnetic fields
A traceable field is generated in a Helmholtz coil. We have equipment capable of generating magnetic fields up to 10 µT in the frequency range DC–1 MHz.
We also carry out customer-specific calibrations.
