CISPR 12:2007+AMD1:2009 CSV Vehicles, boats and internal combustion engines - Radio disturbance characteristics - Limits and methods of measurement for the protection of off-board receivers
Abstract
CISPR 12:2007+A1:2009 The limits in this International Standard are designed to provide protection for broadcast receivers in the frequency range of 30 MHz to 1 000 MHz when used in the residential environment. Compliance with this standard may not provide adequate protection for new types of radio transmissions or receivers used in the residential environment nearer than 10 m to the vehicle, boat, or device. This standard applies to the emission of electromagnetic energy which may cause interference to radio reception and which is emitted from a) vehicles propelled by an internal combustion engine, electrical means, or both; b) boats propelled by an internal combustion engine, electrical means, or both. Boats are to be tested in the same manner as vehicles except where they have unique characteristics as explicitly stated in this standard; c) devices equipped with internal combustion engines. The following changes were made with respect to the previous edition: - deletion of narrowband/broadband determination; - general improvement of wording. This consolidated version consists of the sixth edition (2007) and its amendment 1 (2009). Therefore, no need to order an amendment in addition to this publication.
OTHER PRODUCTS IN THE SAME STANDARD:
Capability:
Spectral scan, spatial scan, peak-hold, continuous scanning, spectral and spatial comparison, scripting, limit lines, and report generation.
Spatial scan time:
Continuous real-time or sub-second single scan for the entire scan area is dependent on spectrum analyzer performance.
Spectral scan time:
45 seconds for L 10 cm x W 10 cm (L 4” x W 4”) PCB with a 100 MHz span and 100 kHz RBW. Scanning area, span, and RBW are user-selectable within spectrum analyzer specifications
EMViewer Software
We recommend you use the EMViewer software for best results. A Yearly subscription or a once-off purchase is available.
Spectral scan, spatial scan, peak-hold, continuous scanning, spectral and spatial comparison, scripting, limit lines, report generation, and notes.
