The precision of the method is determined by the<br \/>\nprecision of the optical spectrum analyzer and the resolution<br \/>\nsetting used. The precision of this procedure may be enhanced by<br \/>\naveraging several sweeps.<\/p>\n<p><strong>Hazards<\/strong><\/p>\n<p>This procedure involves measurements of energized optical<br \/>\nsources. Exercise care to avoid possible eye damage.
