What is BS EN 55016-2-2 - Specification for radio disturbance and immunity measuring apparatus and methods about?
BS EN 55016 is a series on specifications for radio disturbance and immunity measuring apparatus and methods. Radio disturbance is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. BS EN 55016-2-2 specifies the methods of measurement of disturbance power using the absorbing clamp in the frequency range 30 MHz to 1 000 MHz.
Who is BS EN 55016-2-2 - Specification for radio disturbance and immunity measuring apparatus and methods for?
BS EN 55016-2-2 on specifications for radio disturbance and immunity measuring apparatus and methods is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 55016-2-2 - Specification for radio disturbance and immunity measuring apparatus and methods?
The disturbance may degrade the performance of the circuit or even stop it from functioning. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data. BS EN 55016-2-2 describes the classification of different types of disturbance and the detectors appropriate for their measurement. Radio disturbance measurements are reproducible, i.e., independent of the measurement location and environmental conditions, especially ambient noise and free from interactions, i.e., the connection of the EUT to the measuring equipment neither influences the function of the EUT nor the accuracy of the measurement equipment.
These requirements may meet by observing the existence of a sufficient signal-to-noise ratio at the desired measurement level, e.g., the level of the relevant disturbance limit and having a defined measuring set-up, termination, and operating conditions of the EUT. For both manual measurements and automated or semi-automated measurements, measurement times and scan rates of measuring and scanning receivers shall be set so as to measure the maximum emission. Especially where a peak detector is used for prescans, the measurement times and scan rates have to take the timing of the emission under test into account. More detailed guidance on the execution of automated measurements can be found in BS EN 55016-2-2. Using BS EN 55016-2-2 you can specify the methods of measurement of disturbance power using the absorbing clamp in the frequency range 30 MHz to 1 000 MHz.
What’s changed since the last update?
BS EN 55016-2-2:2011 supersedes BS EN 55016-2-2:2004. BS EN 55016-2-2:2011 includes some technical changes with respect to BS EN 55016-2-2:2004. These include:
- Provisions for the use of spectrum analyzers for compliance measurements (Annex D)
- The use of FFT-based test instrumentation (Clauses 3, 6 and 8) is now included
