Keysight N4376D Lightwave Component Analyzer, Getting Started
Using controls or adjustments or performing procedures other
than those specified in the documentation supplied with your
equipment can result in hazardous radiation exposure.
This product complies with overvoltage Category II and Pollution
Degree 2.
Ventilation requirements: When installing the product in a cabinet,
the convection into and out of the product must not be restricted.
The ambient temperature (outside the cabinet) must be less than
the maximum operating temperature of the product by 4 °C for every
100 watts dissipated in the cabinet. If the total power dissipated in
the cabinet is greater than 800 watts, then forced convection must
be used.
Install the instrument so that the power switch is readily identifiable
and is easily reached by the operator. This is the instrument
disconnecting device. It disconnects the mains circuit from the
mains supply before other parts of the instrument. Alternatively, an
externally installed switch or circuit breaker (which is readily
identifiable and is easily reached by the operator) may be used as a
disconnecting device.
Always use the three-prong AC power cord supplied with this
instrument. Failure to ensure adequate earth grounding by not using
this cord may cause instrument damage.
This instrument has autoranging line voltage input. Be sure the
supply voltage is within the specified range.
