System, & Agilent 8166A Lightwave Multichannel System, Fourth Edition
AC Line Power Supply 
Requirements
The Agilent 8163A Lightwave Multimeter System can operate from the single-
phase AC power source that supplies between 100 V and 240 V at a frequency in 
the range 50 to 60 Hz. The maximum power consumption is 120 VA with all 
options installed. 
The Agilent 8164A Lightwave Measurement System can operate from any 
single-phase AC power source that supplies between 100 V and 240 V at a 
frequency in the range from 50 to 60 Hz. The maximum power consumption is 
270 VA with all options installed.
The Agilent 8166A Lightwave Multichannel System can operate from any single-
phase AC power source that supplies between 100 V and 240 V at a frequency in 
the range from 50 to 60 Hz. The maximum power consumption is 450 VA with 
all options installed.
Line Power Cable
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.
CAUTION Please note that the power key on the front panel of the Agilent 8164A Lightwave 
Measurement System does not stop the flow of power to the instrument. The 
power key allows you to switch between stand-by mode and power-on mode. 
When the green power-on LED is lit, you can use the instrument. When the 
orange stand-by mode LED is lit, the Lightwave Measurement System is in stand-
by mode. Do not remove the instrument covers - the power supply is still 
operating in stand-by mode.
If you need to turn off the power, unplug the instrument at the mains or remove 
the power cable connector from the appliance coupler at the rear of the 
instrument. For this reason, the power cable connection should be easily 
accessible - allowing you to turn off the power quickly. If the instrument is in a
