NSS-PLB 06
NATIONAL SEARCH AND
RESCUE SECRETARIAT PERFORMANCE STANDARD
FOR 406 MHZ PERSONAL LOCATOR BEACON (PLB)
APPENDIX B — RADIATION TEST PROCEDURES
WARNING:
Before proceeding with this test, permission is required from the Canadian Mission Control Centre.
B 1.0 MINIMUM RADIATED POWER
The measured power output shall be 5W ± 2 dB and 25 mW -0dB to + 6dB, for the 406 MHz and 121.5 MHz transmitters respectively. The minimum radiated power of the PLB is measured by an equivalence to an isotropic source that produces at a specified distance an RF field equal in strength to the peak RF field produced, by the PLB transmitter operating on a ground plane and at the same distance. The PLB is measured on an elevated metal ground plane, in order to provide a standard test arrangement that eliminates reflections from the site ground.
B 1.1 METHOD OF MEASUREMENT
The method of measurement for both power and antenna characteristics shall be in accordance with the guidance provided in C/S T.007 Annexes A and B.
