3.3 BERT Module
CAUTION
This precision measuring instrument handles high-speed signals at a rate of
10 Gbit/s. If the following precautions are not observed strictly, the instrument will
not be able to deliver its maximum performance and may malfunction.
• Before removing modules from the frame controller, turn the output off.
• Before turning the frame controller off, turn the output off.
• Before connecting cables to or disconnecting cables from the I/O terminals, turn
the output off.
• Before connecting cables to the I/O terminals, tighten the connectors at a
specified torque using a torque wrench.
• Do not leave the DATA OUT, DATA OUT, CLOCK OUT, and CLOCK OUT output
terminals open. Always terminate them with 50
Ω
loads, such as the included
terminators. Likewise, always terminate the cables that are connected to these
output terminals with 50 Ω loads.
• Do not apply a signal that is greater than the specified maximum input voltage to
the input terminals.
• When connecting cables to the I/O terminals, use a grounding strap to prevent
electrostatic discharge.
If the cables are charged with static electricity, the instrument may malfunction.
Always connect cables after they have been discharged.
• Before connecting the unit to the DUT,
*
turn the output off.
• Before connecting the frame controller to the power supply, connect the power
cord to a properly grounded three-prong outlet.
• Always use the specified connector to connect this module’s I/O terminals. Using
unspecified connectors to connect the I/O terminals may cause damage to the
terminals and the connectors.
• When attaching connectors to the I/O terminals, always connect them straight,
not at an angle. Attaching connectors to the I/O terminals at an angle may cause
damage to the I/O terminals or the connectors’ core wires.
• Do not apply external voltage to the output terminals.
* DUT stands for device under test.

ATTENTION
Cet instrument de mesure de précision prend en charge les signaux de haute
vitesse d’un débit de 10 Gbit/s. Si vous ne respectez pas strictement les
précautions suivantes, l’instrument ne peut pas fonctionner au maximum de ses
performances et risque de connaître des dysfonctionnements.
• Avant de retirer les modules du contrôleur, mettre la sortie hors tension.
• Avant de mettre le contrôleur hors tension, mettre la sortie hors tension.
• Avant de brancher les câbles aux bornes d’E/S ou de les débrancher, mettre la
sortie hors tension.
• Avant de brancher les câbles aux bornes d’E/S, serrer les connecteurs selon le
couple spécifié à l’aide d’une clé dynamométrique.
