16 Keysight N4391A/N4392A Optical Modulation Analyzer, Getting Started
1 Introduction
Line power requirements
Line power connectors
In accordance with international safety standards, the instrument has a
three-wire power cable. When connected to an appropriate AC power
receptacle, this cable earths the instrument cabinet. The type of power
cable shipped with each instrument depends on the country of destination.
WARNING
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.
CAUTION
The Keysight N4391A Optical Modulation Analyzer complies with overvoltage
category II and pollution degree 2. It can operate from the single-phase AC
power source that supplies between 100 V and 240 V (max. voltage fluctuation
10%) at a frequency in the range of 50 to 60 Hz. The maximum power
consumption of the optical modulation analyzer is 40 VA (N4391A) or 375 VA
(N4392A) with all options installed.
Please refer to the documentation for your digital signal analyzer for information
on its line power requirements.
