Summary of KN 301 489-32 Unintentional Radiator EMC Testing
The KN 301 489-32 standard EMC test method covers the ground and wall-probing radar equipment and ancillary equipment in respect to EMC. Technical specifications such as the antenna port and emissions from the enclosure port are not included. However, this document specifies the applicable test conditions, performance assessment, and criteria for GPR, WPR, and the associated ancillary equipment.
Electromagnetic compatibility testing is described as when a device does not interfere with its electromagnetic (EM) environment and it does not emit levels of EM energy that cause electromagnetic interference (EMI) in other devices in the vicinity. Other definitions are used multiple times within this standard. This includes the following.
Ground Probing Radar (GPR): A radar application and equipment, used to probe and examine/analyze sub-surface material or structure.
Wall Probing Radar (WPR): A radar application and equipment used to examine/analyze material in walls.
Scope of KN 301 489-32 EMC Ground and Wall Probing Equipment
During the test, the EUT is operated as intended and for this type of equipment, no modulation is required. For equipment with the capability of using different imaging heads, each one is tested independently.
The GPR and WPR equipment process signals using transmitters. These transmitters emit repetitive or random pulses. The equipment will present the received signal as either an analog time-varying voltage or as a digitized version of the time-varying detector output.
To confirm that the equipment is operational during testing, the manufacturer will provide means which allow monitoring of the analog or digital information.
For the EUT, the performance assessment is based on three factors.
- The maintenance function(s);
- The way the eventual loss of function(s) can be recovered;
- Unintentional behavior of the EUT.
Lastly, performance criteria for GPR and WPR equipment during and after immunity testing are specific to this KN 301 489-32 test. Performance criteria A is for immunity testing with phenomena of continuous nature. Performance Criteria B is used for immunity tests with phenomena of transient nature.
