Using a Laser Source
The Agilent 83433A contains an IEC LASER Class 3B according to IEC 60825.
The total power of light energy radiated out of the LASER OUT connector is
8.5 to 11 dBm. Use caution when making or breaking connections to the front
panel.
Three safety mechanisms are provided:
• A laser safety shutter over the front-panel
CLASS IIIB INTERNAL LASER OUT
con-
nector. This shutter must be opened when attaching or removing cables.
• A key switch on the front panel must be turned on to enable the laser. When
this key is turned on, the front-panel LED next to the key will light.
• A REMOTE SHUTDOWN connector on the rear panel. This connector must
be shorted for the laser to operate. When the short is removed from the con-
nector, the accessible radiation does not exceed the AEL for FDA Laser
Class 1 (IEC Laser Class 1) according to IEC publication CE/IEC 821-
1: 1993. Use your own short, switch, or other circuitry to control the RE-
MOTE SHUTDOWN.
To enable the laser, follow these three steps:
1 Make sure a short is connected to the rear panel REMOTE SHUTDOWN
connector. The laser will
not operate without the short connected.
2 Insert the key into the transmitter’s front panel.
3 Turn the key to turn the laser source on.
W A R N I N G Do not , under any circumstances, look into the optical output or any
fiber/device attached to the output while the laser is in operation.
W A R N I N G Do not enable the laser when no fiber or equivalent device is attached
to the OPTICAL OUTPUT connector.
