This chapter introduces the main performance characteristics and application scope of the 3986 series
noise figure analyzer, as well as the methods for proper operation and precautions for electrical safety.
General………………………………………………………………………………………………………5
Safety guide…………………………………………………………………………………………………5
2.1General
The 3986 series noise figure analyzer can cover a frequency range of 10MHz to 50GHz. It contains a
highly sensitive receiver, user-friendly interface, high-definition dual-channel display, an abundance of
external connection ports, dual-noise source driver, etc. It is able to measure the noise figure of
amplifiers, downconverters and upconverters; supports the measurement of multi-stage converters; and
supports extended frequency range measurements. With complete loss compensation function, the loss
in the measurement channel can be compensated by means of fixed and/or table form before and/or
after the device under test，which would greatly benefit precise measurement of noise figure of
automatic test system or microwave chips.The limit lines function provides pass/fail notification to
simplify pass/fail assessment. The product can be applied to microwave and millimeter wave amplifiers,
mixers, attenuators and other components to measure noise figure and gain, and is suitable for scientific
research, production, testing, and technical security evaluation in such fields as radar, communication
and navigation.
A mechanical switch is built at the input port of the 3986D/E/F/H series noise figure analyzer to switch
the frequency range between 10MHz to 4GHz and 4GHz to 18/26.5/40/50GHz. The mechanical switch
has a limited service life. To maximize the reliable life of the switch, please avoid frequencies setting
across 4 GHz as much as possible.

2.2.1.2 Safety signs in the manual
For the purpose of this manual, the following safety warning signs are used to remind the user of
operating the instrument safely and paying attention to relevant information,:
DANGER indicates a situation which, if not being avoided, will lead to
personal injury or equipment damage.
WARNING indicates a situation which, if not being avoided, will lead to
personal injury or equipment damage.
CAUTION indicates a situation which, if not being avoided, will lead to
minor or moderate personal injury or equipment damage.
ATTENTION indicates an important information rather than a danger.
NOTE indicates information about the instrument and its operation.
2.2.2 Operation status and position
Before instrument operation, please pay attention to the followings:
1) Unless otherwise stated, the 3986 series noise figure analyzer must satisfy the following
environmental requirements: be placed on a flat surface. The maximum altitude at which the
instrument is operated and transported should not be greater than 4,600 m. The actual supply
voltage is allowed to vary within ±10% of the specified voltage, and the supply frequency is allowed
to vary within ±5% of the specified frequency.
2) Unless otherwise stated, the instrument not subject to waterproof treatment should not be placed on
a watery surface, vehicle, cabinet, table or other unfixed objects that don't meet the load-bearing
condition. Please place and fix the instrument reliably on the surface of a solid object (e.g. anti-static
workbench).
3) Do not place the instrument in an environment that is prone to fogging. For example, if the
instrument is moved in an alternate cooling and heating environment, water droplets will be formed
on the instrument, causing electric shock and other hazards.
4) Do not place the instrument on the surface of a radiating object (e.g. radiator). The ambient
temperature in which the instrument works should not exceed the value given in the section
regarding description of relevant indicators of the product. Overheating of the product will result in
electric shock, fire and other hazards.
5) Do not insert anything into the instrument through the openings on the housing or cover the notches
or openings on the instrument because they are designed for internal ventilation to prevent the
instrument from overheating.

2.2.3 Electrical safety
Electrical safety precautions of the instrument:
1) Before turning on the instrument, ensure that the supply voltage matches the indicated supply
voltage of the apparatus.
2) With reference to the power requirements on the instrument's rear panel, a three-core power cord is
used to ensure reliable grounding of the power wire during use. Poor floating or grounding may
cause damage to the instrument or harm to the user.
3) Do not damage the power cord; otherwise leakage will occur, which may damage the instrument
and even cause injury to the operator. If an external power cord or terminal board is used, check it
before use to ensure the electrical safety.
4) If the power outlet is not equipped with ON/OFF switch, the instrument can be directly unplugged for
deenergization. For this purpose, it is necessary to ensure that the instrument can be plugged and
unplugged conveniently.
5) Do not use a damaged power cord. It is necessary to check the integrity and safety of the power
cord before connecting it to the instrument, and place it reasonably to avoid the influence due to
human factors, e.g. the operator is tripped by an excessively long power cord.
6) The outlet should be kept clean and tidy, and the plug and outlet should be contacted properly and
firmly.
7) The outlet and power cord should not be overloaded; otherwise, fire or electric shock will be caused.
8) Unless otherwise permitted, the instrument enclosure should not be opened; otherwise, the internal
circuits and components will be exposed, causing unnecessary damage or injury.
9) If the instrument needs to be fixed at the test site, a protective ground wire should be installed
between the test site and the instrument by a qualified electrician.
10) Appropriate overload protection measures should be taken to avoid instrument damage or personal
injury caused by overload voltage (in the event of lightning for example).
11) Please note that if the instrument catches fire, it may release gases or liquids that are toxic to the
human body.
2.2.4 Operation precautions
1) The instrument operator should have certain professional technical knowledge and certain ability of
emergency response.
2) Before moving or transporting the instrument, please refer to the relevant instructions in ―2.2.6
Transport‖.
3) If the instrument operator suffers from allergy (e.g. rash, frequent sneezing, red eyes, or breathing
difficulty) during operation due to the inevitable use of substances (such as nickel) that may cause
personal allergy in the process of production of the instrument, please seek medical advice promptly
to find the cause and resolve the symptom.
4) Before dissembling the apparatus for waste management, please consult the instructions in the
―2.2.7 Waste disposal/environmental protection‖.
5) As the radio frequency instrument will produce a high level of electromagnetic radiation, a pregnant
woman and an operator with a heart pacemaker need special protection.
6) To prevent static electricity from causing damage to the instrument, an anti-static table mat, footpad,
and wristband should be worn to manage static voltage so that it does not exceed 500 V.
