Radio Frequency Emissions

Conducted and radiated RF emissions emanating from vehicle components are generally measured using procedures based on CISPR 25.

Measurement procedures can also be tailored to conform to the manufacturer’s custom requirements. 

Transient Emissions and Immunity

Radio Frequency Immunity

The ability of a device to operate without interference in the presence of a high RF field can be assessed using various methods, depending on the reference standard and frequency range.

Some common methods of coupling the RF energy to the device include: 

  • TEM Cell 4 ISO 1145243
  • Stripline 4 ISO 1145245
  • Bulk Current Injection 4 ISO 1145244
  • Direct Injection 4 ISO 1145247
  • Free Field 4 ISO 1145242

RF Remote Key Measurements

RF remote transmitters and receivers must comply with the radio communication standards applicable to the destination market.

In Australia the applicable standard is AS/NZS 4268, whilst in Europe the applicable standards are ETSI EN 300 22041 (emissions) and ETSI EN 301 48941(immunity).

FCC requirements must be met for the US market. 

Electrostatic Discharge

Electrostatic discharges are common events in vehicles as occupants enter and exit after a period of travel.

These ESD events can easily reach levels of ±25kV and may cause momentary loss of operation or permanent damage to sensitive electronic circuitry.
