1.1 Test Conditions

This section provides the test conditions for the CE and RE measurements.

  • Input supply:
    • Fully charged 12-V car battery
  • Load on load switch evaluation module:
    • Common Use Load, 125 Ω (40 mA)
    • Maximum Current, 25 Ω (200 mA)
  • Antenna configurations for radiated emission measurements
    • Monopole: 150 kHz–30 MHz
    • Biconical (Horizontal/Vertical): 30 MHz–200 MHz
    • Log Periodic (Horizontal/Vertical): 200 MHz–1 GHz

Table 1-1 shows EMI receiver settings for the conducted emission measurements.
