Please pay attention to the following laser safety warnings:
• Under no circumstances look into the end of an optical cable attached
to the optical output when the device is operational. The laser
radiation can seriously damage your eyesight.
• Do not enable the laser when there is no fiber attached to the optical
output connector.
• The laser is enabled by the software. The laser is on when the green
LED above the LO Output connector is lit.
• The use of the instruments, such as microscopes or spectacles, with
this product will increase the hazard to your eyes.
• The laser module has built-in safety circuitry which will disable the
optical output in the case of a fault condition.
• Refer servicing only to qualified and authorized personnel.
All the connectors are very sensitive to electrostatic discharge (ESD).
When you connect a device or cable that is not fully discharged to these
connectors, you risk damage to the instrument and expensive instrument
repairs.
Electrostatic discharge (ESD) can damage the circuits of the M829xA.
Avoid applying static discharges to the front-panel connectors. Before
connecting any coaxial cable to the connectors, momentarily short the
center and outer conductors of the cable together. Avoid touching the
front-panel connectors without first touching the frame of the
instrument. Be sure the instrument and all connected devices (DUT, etc.)
are properly earth-grounded (to a common ground) to prevent buildup of
static charge and electrical over-stress.
