Caution
Do not exceed the operating input power level,
voltage level, current level, and signal type that is
appropriate for the instrument being used. Refer to
your instrument's operation manual for safe
operating practices and device limitations.
Electrostatic Discharge (ESD) can damage the highly
sensitive circuits in the instrument. ESD is most
likely to occur as test devices are being connected to,
or disconnected from, the instrument's front and rear
panel ports and connectors. You can protect the
instrument and test devices by wearing a
static-discharge wristband. Alternatively, you can
ground yourself to discharge any static charge by
touching the outer chassis of the grounded
instrument before touching the instrument's front
and rear panel ports and connectors. Avoid touching
the test port center conductors unless you are
properly grounded and have eliminated the
possibility of static discharge.
Repair of damage that is found to be caused by
electrostatic discharge is not covered under
warranty.

For Safety
WARNING
Always refer to the operation manual when working near locations
where the alert mark, shown on the left, is attached. If the opera-
tion, etc., is performed without heeding the advice in the operation
manual, there is a risk of personal injury. In addition, the equip-
ment performance may be reduced. Moreover, this alert mark is
sometimes used with other marks and descriptions indicating
other dangers.
WARNING
When supplying power to this equipment, connect the accessory
3-pin power cord to a 3-pin grounded power outlet. If a grounded
3-pin outlet is not available, use a conversion adapter and ground
the green wire, or connect the frame ground on the rear panel of
the equipment to ground. If power is supplied without grounding
the equipment, there is a risk of receiving a severe or fatal electric

components. Only qualified service technicians with a knowledge
of electrical fire and shock hazards should service this equipment.
There are high-voltage parts in this equipment presenting a risk
of severe injury or fatal electric shock to untrained personnel. In
addition, there is a risk of damage to precision components.
WARNING
Use two or more people to lift and move this equipment, or use an

Static Safety
Anritsu products comply with the immunity requirements defined by the European Immunity Standard
EN 61000-4-2:1995/EN50082-1:1997-4kV CD, 8kV AD for static discharge. This standard requires that
the products survive air discharge static levels of 8 kV, and direct contact discharge static levels of 4 kV.
The standard also states, "the static electricity discharges shall be applied only to such points and
surfaces of the equipment which are accessible to personnel during normal usage."
Anritsu, as well as most other manufacturers of VNA test equipment, interpret this standard to mean
immunity that excludes direct static discharge to the test port center conductor. To prevent direct contact
under normal usage, the test port connectors are designed with recessed center conductor pins. The
following warning is also affixed near the test ports:
