IEC 61967-1 pdf download – Integrated circuits — Measurement of electromagnetic emissions, 150 kHz to 1 GHz — Part 1: General conditions and definitions
1Scope
This part of lEC 61967 provides general information and definitions on measurement ofconducted and radiated electromagnetic disturbances from integrated circuits. It also providesa description of measurement conditions,test equipment and set-up as well as the testprocedures and content of the test reports. A test method comparison table is included asannex A to assist in selecting the appropriate measurement method(s).
The object of this standard is to describe general conditions in order to establish a uniformtesting environment and obtain a quantitative measure of RF disturbances from integratedcircuits (IC). Critical parameters that are expected to influence the test results are described.Deviations from this standard are noted explicitly in the individual test report. The measure-ment results can be used for comparison or other purposes.
Measurement of the voltage and current of conducted RF emissions or radiated RFdisturbances, coming from an integrated circuit under controlled conditions,yields informationabout the potential for RF disturbances in an application of the integrated circuit.

3 Definitions
For the purpose of this part of lEC 61967,the following definitions， taken mostly fromIEC 60050(161).apply.
3.1
artificial networkAN
agreed reference load impedance (simulated), presented to the EUT by networks (forexample，extended power or communication lines) across which the RF disturbance voltage ismeasured and which isolates the apparatus from the power supply or loads in that frequencyrange
[IEV 161-04-05,modified]
3.2
associated equipment
transducers (for example,probes, networks and antennas) connected to a measuring receiveror test generator; also transducers (for example，probes, networks,and antennas) which areused in the signal or disturbance transmission path between an EUT and measuringequipment or a (test-) signal generator
3.3
auto sweep
fastest calibrated sweep which a spectrum analyser will automatically select based on startfrequency, stop frequency, resolution bandwidth and video bandwidth
3.4
broadband emission
emission which has a bandwidth greater than that of a particular measuring apparatus orreceiver
[IEV 161-06-11, modified]
3.5
common mode voltageasymmetrical voltage
mean of the phasor voltages appearing between each conductor and a specified reference,usually earth or frame
[IEV 161-04-09]
3.6
common mode current
in a cable having more than one conductor，including shields and screens,if any,themagnitude of the sum of the phasors representing the currents in each conductor
[lEV 161-04-39]
3.7
conducted emissions
transients and/or other disturbances observed on the external terminals of a device during itsnormal operation
3.8
continuous disturbance
RF disturbance with a duration of more than 200 ms at the lF-output of a measuring receiver,which causes a deflection on the meter of a measuring receiver in quasi-peak detection modewhich does not decrease immediately
[IEV 161-02-11, modified]
