EN55025 |
|
Scope |
Vehicles, boats and other internal combustion engines. |
|
Type
|
RF emissions measurement for the protection of on-board receivers. |
The table below shows the test requirements and ancillary items. Common to all tests are an EMC analyser (SA1002 or SA3000), pre-selector (RF910), pre-amplifier (SA1020) and associated software (included with the EMC analyser).

Clause 5:
Emissions received by antenna on same vehicle.
Antenna is the one normally fitted to the vehicle. If non fitted, use 1m monopole (band B) or loaded ¼ wave monopole (band C & D).
Antenna matching unit reqd: Input imp. >100K II <10pF , Output imp.: 50R
Additional tests when vehicle is in charging mode.
AC mains: LISN: 50uH/50R AMN CISPR16
DC cable: LISN: 5uH/50R HV-AN High voltage
Comms lines: AAN (Artificial Asymmetric Network)
