Safety-2 PN: 10410-00304 Rev. A ME7828A MM
For Safety
Warning Always refer to the operation manual when working near locations at which
the alert mark, shown on the left, is attached. If the operation, etc., is
performed without heeding the advice in the operation manual, there is a
risk of personal injury. In addition, the equipment 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 shock.
Warning
This equipment can not be repaired by the operator. Do not attempt to
remove the equipment covers or to disassemble internal 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
equipment cart. There is a risk of back injury if this equipment is lifted by
one person.
Caution
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.

1-6 Electrostatic Discharge (ESD) Prevention
All electronic devices, components, and instruments can be damaged by electrostatic discharge. It is important
to take preventative measures to protect the instrument and its internal subassemblies from electrostatic
discharge.
An ESD safe work area and proper ESD handling procedures that conform to ANSI/ESD S20.20-1999 or
ANSI/ESD S20.20-2007 is mandatory to avoid ESD damage when handling subassemblies or components
found the 3738A test set.
Take steps to eliminate the static charges built-up on coaxial cables prior to connecting them to the VNA
System test ports. This can be done by terminating one end of the cable with the short from the calibration kit
and then grounding the outer conductor of the connector of the cables.
