Division 3.1 Frequency range, dwell times, polarisation

The vehicle shall be exposed to electromagnetic radiation in the 20 to 2 000 MHz frequency ranges in vertical polarisation.

The test signal modulation shall be:

• AM, with 1 kHz modulation and 80 % modulation depth in the 20-800 MHz frequency range, and

• PM, t on 577 μs, period 4 600 μs in the 800-2 000 MHz frequency range,

if not otherwise agreed between technical service and vehicle manufacturer.

Frequency step size and dwell time shall be chosen according to ISO DIS 11451-1:2003.
