Environmental Requirements

This instrument is suitable for the following environment:
Indoor use.

Pollution degree 2

In operating: altitude lower to 3000 meter；in non-operating: altitude lower to 15000 meter.

Operating temperature 0 ℃ to ﹢ 40 ℃ ; Storage temperature -20 ℃ to +70 ℃ (unless otherwise

specified).
In operating, humidity temperature below to +35℃, ≤90％ relative humidity;


There are ventilation opening on the rear panel and side panel of the instrument. So please keep the air
flowing through the vents of the instrument housing. To prevent excessive dust from blocking the vents,
please clean the instrument housing regularly. The housing is not waterproof, please disconnect the power
supply first and then wipe the housing with a dry cloth or a slightly moistened soft cloth.

Connecting Power Supply

The specification of AC power supply that can input
Please use the attached power lead to connect to the power port.
Connecting to service cable
This instrument is a Class I safety product. The supplied power lead has good performance in terms of case
ground. This spectrum analyzer is equipped with a three-prong power cable that meets international safety
standards. It provides good case grounding performance for the specification of your country or region.
Please install AC power cable as follows：
• ensure the power cable is in a good condition.
• leave enough space for connecting the power cord.
• Plug the attached three-prong power cable into a well-grounded power socket.

Electrostatic Protection

Electrostatic discharge may cause damage to component. Components can be damaged invisibly by
electrostatic discharge during transportation, storage and use.
The following measure can reduce the damage of electrostatic discharge,
• Testing in antistatic area as far as possible；
• Before connecting the power cable to the instrument, inner and outer conductors of the instrument should
be briefly grounded to discharge static electricity;
• Ensure all the instruments are properly grounded to prevent the accumulation of static
