• 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.
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.
