This standard delineates the requirements of electromagnetic noise instrumentation for the frequency range of 10 Hz to 40 GHz incorporating quasi-peak, peak, rms and average detectors.
NOTE,— Examples of the types of voltages, currents, and fields to be measured are unmodulated and modulated sine-waves, and components of electric and electromagnetic disturbances, including transients that may interfere with the operation of communication, electric, or electronic equipment.
The basic instrument is a frequency-selective voltmeter (FSVM). With appropriate coupling devices, such as antennas and current probes, the instrumentation will also measure other physical quantities such as field strength and current.
The parameters for the quasi-peak detector are specified to agree with the requirements of the Comit6 International Special des Perturbations Radioelectriques (International Special Committee on Radio Interference) (CISPR) [see CISPR Publication 16 (1987)]. An optional discharge time constant is also specified.
The requirements of this specification should not be construed to imply that one instrument is required to cover the entire frequency range or that the instrument is permitted to have only the specified detector or detectors. Many users have measurement requirements over a smaller frequency range or may require additional detection capabilities.
Although spectrum analyzers are frequently used in electromagnetic-noise measurements, it is not within the scope of the present standard to cover such instruments. A separate document covering spectrum analyzers for use from 20 Hz to 40 GHz is in preparation as a proposed supplement to this standard. However, a measuring set configured around a spectrum analyzer that meets the requirements of this standard may be used.
For measurements made on paired telecommunications lines, refer to IEEE Std 743-1984. Instrumentation specifications for measurement of telecommunications terminal equipment for compliance to technical standards of regulatory authorities are under consideration.
