[F16. Frequencies U.K.
6.1. Measurements U.K.
Measurements shall be made throughout the 30 to 1 000 MHz frequency range. To confirm that the vehicle meets the requirements of this Annex, the Testing Authority shall test at up to 13 frequencies in the range, e.g. 45, 65, 90, 120, 150, 190, 230, 280, 380, 450, 600, 750, 900 MHz. In the event that the limit is exceeded during the test, investigations shall be made to ensure that this is due to the vehicle and not to background radiation.
6.1.1. The limits apply throughout the frequency range 30 to 1 000 MHz. U.K.
6.1.2. Measurements can be performed with either quasi-peak or peak detectors. The limits given in Annex I, paragraphs 6.2 and 6.5 are for quasi-peak. If peak is used, add 38 dB for 1 MHz bandwith or subtract 22 dB for 1 kHz band width. U.K.
6.2. Tolerances U.K.
| Spot frequency (MHz) | Tolerance (MHz) |
|---|---|
| 45, 65, 90, 120, 150, 190 and 230 | ± 5 |
| 280, 380, 450, 600, 750 and 900 | ± 20 |
The tolerances apply to frequencies quoted and are intended to avoid interference from transmissions operating on or near the nominal spot frequencies during the time of measurement.]
