USER NOTICE
This chapter helps you in preparing the spectrum
analyzer for use and provides the information to
start using the spectrum analyzer correctly.
General Inspection
When you receive your new instrument, it is recommended that
you check the instrument following these steps:
Steps
1. Check for transportation damage.
If it is found that the packaging carton or the
foamed plastic protection cushion has suffered
serious damage, do not throw it away until the
complete device and its accessories have been
electrically and mechanically checked.
2. Check the Accessories
Please ensure that all the listed accessories are
present and undamaged, if any problems are
found please contact your distributor.
3. Check the Complete Instrument
If there is any physical damage, operational
fault, or performance issue please contact your
distributor or GW Instek’s local office. If there
is any damage to the instrument please ensure
you keep the original packaging. Ideally you
should always keep the original packaging if
the instrument must be returned for repair.

Safety Precaution before Operation
Check Power Supply
The analyzer is equipped with a three-wire power cord in
accordance with international safety standards. The product must
be grounded properly before being powered on, as floating or
improper ground may cause damage to the instrument or personal
injury.
Make sure the grounding conductor of the spectrum analyzer is
grounded before turning on the instrument. After which the AC
power cord can be connected. Do not use a non-ground power cord.
Allowed Variation Range of Supply Power Parameters
The spectrum analyzer is compatible with 100V~240V, 50Hz-60Hz
AC power. The table below lists the power requirement to run the
spectrum analyzer.
Power Supply Parameter
Compatible Range
Voltage
100 - 240 VAC
Frequency
50 - 60 Hz ±10％
Power
28W
To prevent or lower the risk of damage to the spectrum analyzer
from power interference between instruments, especially from peak
pulses produced by large power consumption instruments, a
220V/110V AC regulated power supply is recommended.
Power Cord Selection
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 must be rated greater than 250Vac and 2A.

WARNING
Improper grounding may cause damage to the
instrument, or result in personal injury. Make sure the
grounding conductor of the spectrum analyzer is
grounded before turning on the instrument.
Always use a well-grounded power source. Do not use
an external power cable, power cord or an auto
transformer without grounded protection. If this
product is to be powered via an external auto
transformer for voltage reduction, ensure that its
common terminal is connected to a neutral (earthed
pole) of the power supply.
Make sure the supply power is stable before turning
on the analyzer to protect it from damage. Refer to
“First Time to Power on”on page 9

Electro-static Discharge (ESD) Protection
ESD is an issue often ignored by users. Damage from ESD on the
instrument is unlikely to occur immediately but will significantly
reduce the reliability of it. Therefore, ESD precautions should be
implemented in the work environment, and applied daily.
Generally, there are two steps to manage ESD protection:
1. Conductive table mats to connect hands via
wrist bands
2. Conductive ground mat to connect feet via
ankle straps
Implement both protection methods will provide a good level of
anti-static protection. If used alone, the protection will not be as
reliable. To ensure user’s safety, anti-static components should
offer at least 1MΩ isolation resistance.
WARNING
The above ESD protections measures cannot be used
when working with over 500V!
Make good use of anti-static technology to protect components
from damage:
1. Quickly ground the internal and external
conductor of the coaxial cable before it is
connected with the spectrum analyzer.
2. Staff must wear anti-static gloves before
touching the connector cord or doing any
assemble work.
3. Assure all the instruments are grounded
properly to avoid static storage.

First Time to Power on
Connect the three-pin AC power cord into the instrument. Insert
the plug into a power socket provided with a protective ground.
WARNING
Check the power source before turning on the
spectrum analyzer, to protect the device from damage.
Steps
1. Press the power switch on the bottom left
of the front panel.
2. Self-initialization takes about 30 seconds, after
the boot screen the spectrum analyzer will
default to the scanning curve.
3. After power on, let the spectrum analyzer warm
up for 60 minutes for stabilization to obtain the
most accurate results.
