2.6 Performing High Resolution Measurement
WARNING
• During measurement, light is transmitted from the light source ports. Do not disconnect the
connected optical fiber cables. Visual impairment may occur if the light enters the eye.
• Close the covers of any light source ports that do not have optical fiber cables connected
to them. Visual impairment may occur if light that is mistakenly emitted from these ports
enters the eye.

AVERTISSEMENT
• Lorsque l’AQ7280 génère de la lumière, la lumière est émise à travers les ports de source
lumineuse. Ne pas débrancher les câbles de fibre optique connectés. Des lésions oculaires
peuvent être causées si le faisceau lumineux pénètre l’œil.
• Couvrir les caches des ports de source lumineuse libres. Sur les modèles dotés de deux
ports de source lumineuse ou plus, protéger les yeux contre l’émission accidentelle de
lumière depuis le mauvais port.
When analyzing waveforms in real-time measurement, you can limit the range to be analyzed and
measure at high resolution to obtain detailed measurements.
