Introduction

This specification is based on JJF 1071-2010 "Rules for the Compilation of National Metrology and Calibration Specifications" and JJF 1059:1-2012 "Evaluation and Expression of Measurement Uncertainty" was compiled: This specification refers to IEEE1309-2013 "IEEEStandardforCalibrationofElectromagnetic FieldSensorsandProbes (ExcludingAntennas) from9kHzto40GHz" in the relevant clauses Line preparation: It mainly stipulates the calibration method of electromagnetic field probe with frequency range of 10kHz~100MHz: Calibration items include: electric field intensity, magnetic field intensity, magnetic induction intensity and isotropy: And the measurement is given in the appendix Example of uncertainty evaluation for This specification is released for the first time: 10kHz~100MHz electromagnetic field probe Calibration specification

1 Scope

This specification specifies the electromagnetic field probes (including electric field probes, magnetic field probes, etc:) in the 10kHz~100MHz frequency band: The calibration method called field probe is suitable for the calibration of field probes used in electromagnetic compatibility testing and other fields: Other types The field probe (except the antenna) can also be used as a reference:

2 Reference documents

This specification refers to the following documents: IEEEStd1309-2013 9kHz~40GHz electromagnetic field probe and sensor (except antenna) calibration [IEEEStandardforCalibrationofElectromagneticFieldSensorsandProbes(Excluding Antennas)from9kHzto40GHz]: For dated reference documents, only the dated version applies to this specification; for undated references The latest version (including all amendments) is applicable to this specification:

3 Terms and units of measurement

3:1 Field sensor fieldsensor An electrically small-sized device used to measure electric or magnetic fields, does not contain electronic components, and should have as little disturbance as possible The field being tested: Theoretically its transfer function (the ratio of the output signal to the input electromagnetic field) can be measured by its physical parameters Number and electrical properties of materials are obtained: 3:2 fieldprobe Contains a field sensor or a combination of several field sensors, diode detectors, resistors, amplifiers and other electronics Pieces: It is used to measure the radio frequency field component in a certain medium, and should disturb the measured field as little as possible: Theoretically The output cannot be obtained by simply measuring its physical parameters: Field probes include electric field probes and magnetic field probes: 3:3 E-fieldprobe A field probe capable of measuring the electric field strength E (unit: V/m): 3:4 H-fieldprobe It can measure the magnetic field intensity H (unit is A/m) or magnetic induction intensity B (unit is Wb/m2 or T) Field probe: Note: 1Wb/m2=1T=106μT: 3:5 readout device readoutdevice The output signal of the acquisition field probe is converted into a readable signal and sent to the electronic device of the data acquisition analyzer:

4 overview

Field probes are usually divided into passive and active two types: passive field probes include field sensors, diode detectors and high-impedance transmitters: ......
