Checking Shipment and Order List

We recommend you check the shipment and order
list according to the following procedure when you
receive the shipment.

• Inspect the shipping container for damages.
Signs of damage may include a dented or torn
shipping container or cushioning material that
indicate signs of unusual stress or compacting.

• Carefully remove the contents from the shipping
container, and check your shipment.

• For any question or problem, contact Agilent
Technologies Customer Contact Center (CCC) for
consultant and service. See “Contact Agilent

Technologies" on page 24.

Power Requirements

The AC power supply must meet the following
requirements

Voltage : 100 VAC to 240 VAC

Frequency: 50 Hz to 60 Hz

Power: Maximum 62 W

The analyzer is equipped with a three- wire power
cord, in accordance with international safety
standards. This cable grounds the analyzer cabinet
when connected to an appropriate power line
outlet. The cable appropriate to the original
shipping location is included with the analyzer.

Various AC power cables are available that are
unique to specific geographic areas. You can order
additional AC power cables for use in different
areas. The table AC Power Cords lists the available
AC power cables, the plug configurations, and
identifies the geographic area in which each cable
is appropriate.

The detachable power cord is the product
disconnecting device. It disconnects the mains
circuits from the mains supply before other parts
of the product. The front switch is only a standby
switch and do not disconnect instrument from
LINE power.

Safety Considerations

Agilent has designed and tested the N9340A
handheld spectrum analyzer for Measurement,
Control and Laboratory Use in accordance with
Safety Requirements IEC 61010- 1: 2001,
UL 61010- 1 (2004), and CSA C22.2 No.61010- 1- 04.
The tester is supplied in a safe condition. The
N9340A is also designed for use in Installation
Category II and Pollution Degree 2 per IEC 61010
and IEC 60664 respectively.

Read the following safety notices carefully before
you start to use a N9340A handheld spectrum
analyzer to ensure safe operation and to maintain
the product in a safe condition.

Getting Started 2

WARNING

Personal injury may result if the analyzer’s cover is
removed. There are no operator-serviceable parts inside.
Always contact Agilent qualified personnel for service.
Disconnect the product from all voltage sources while it
is being opened.

WARNING

This product is a Safety Class I analyzer. The main plug
should be inserted in a power socket outlet only if
provided with a protective earth contact. Any
interruption of the protective conductor inside or outside
of the product is likely to make the product dangerous.
Intentional interruption is prohibited.

CAU-CAUTION

NOTE

Danger of explosion if the battery is incorrectly replaced.
Replace only with the same type recommended.

Do NOT dispose of batteries in a fire.
Do NOT place batteries in the trash. Batteries must be

recycled or disposed of properly.

Recharge the battery only in the analyzer. If left unused, a
fully charged battery will discharge itself over time.

Never use a damaged or worn-out adapter or battery.
Charging the batteries internally, even while the analyzer
is powered off, the analyzer may become warm. To avoid
overheating, always disconnect the analyzer from the AC
adapter before storing the analyzer into the soft carrying
case.

We strongly recommend you to connect the automotive
adapter to the power output connector for IT equipment,
when charging the battery on your automotives.

The VxWorks operating system requires full conformity to
USB 1.1 or USB 2.0 standards from a USB disk. Not all the
USB disk are built that way. If you have problems
connecting a particular USB disk, please reboot the
analyzer before inserting the next.

Temperature extremes will affect the ability of the battery
to charge. Allow the battery to cool down or warm up as
necessary before use or charging.

Storing a battery in extreme hot or cold places will reduce the
capacity and lifetime of a battery. Battery storage is
recommended at a temperature of less than 45

Electrical Requirements

This analyzer allows you to use either the original

adapter shipped with the analyzer for power
supply to the analyzer.

Electrostatic Discharge (ESD) Precautions

This analyzer was constructed in an ESD protected
environment. This is because most of the
semiconductor devices used in this analyzer are
susceptible to damage by static discharge.

Depending on the magnitude of the charge, device
substrates can be punctured of destroyed by
contact or mere proximity of a static charge. The
result can cause degradation of device
performance, early failure, or immediate
destruction.

These charges are generated in numerous ways,
such as simple contact, separation of materials,
and normal motions of persons working with static
sensitive devices.

When handling or servicing equipment containing
static sensitive devices, adequate precautions must
be taken to prevent device damage or destruction.
Only those who are thoroughly familiar with
