YD/T 2583.14-2013Requirements and measurement methods of electromagnetic compatibility for cellular mobile telecommunications equipment. Part 14: LTE user equipment and ancillary equipment (English PDF)

3.1 Terms and definitions

The following terms and definitions apply to this document.

3.1.1

Ancillary equipment

The equipment used to connect with the wireless communication device,

which at the same time satisfies the following conditions.

3.1.5

Continuous disturbance

It refers to the electromagnetic interference having an effect on certain

equipment which cannot be clearly differentiated as a series of effect.

3.1.6

Data application ancillary

It refers to the ancillary equipment which accesses the universal mobile

telecommunication system (UMTS) via the user equipment, thus providing

the transmitting and receiving data.

3.1.7

Enclosure port

It refers to the physical boundary through which the electromagnetic field

radiates or invades. The physical boundaries of the plugins are defined by

the host unit.

3.1.8

Host equipment

It refers to any equipment which can realize functions completely without

connecting to the wireless communication equipment. AND the wireless

communication device only provides additional functionality.

3.2 Abbreviations

The following abbreviations apply to this document.

4.1 General conditions

The equipment under test shall be tested in a normal test environment. If the

test conditions are uncertain, the manufacturer shall provide information on the

humidity, temperature and supply voltage of the equipment under test. These

test conditions shall be documented in the test report.

4.2 Test arrangement

The radio frequency input signal frequency shall be selected from the

appropriate E-UTRA absolute radio frequency channel number.

It may select an appropriate base station simulator (also referred to herein as a

test system) to establish a communication link. The base station simulator shall

be placed outside the test environment.

4.3 Narrowband response of the receiver

The narrowband response as generated by the receiver/transceiver during the

discrete frequency test process shall be determined by the following method.

5.1 General

It is same as the clause 5.1 of GB/T 22451-2008.

The relevant contents on the intermediate frequency filter bandwidth in front of

the receiver demodulator as mentioned in clause 5.1 of GB/T 22451-2008 are

not applicable to the radio equipment within the scope of this standard.

5.2 EUT which can establish continuous communication

connections

It is same as the clause 5.2 of GB/T 22451.2008.

The test arrangement conditions and signals as defined in chapter 4 apply to

the equipment under test AND the equipment under test to which ancillary

equipment is added for the purposes of establishing the communication link.

The equipment performance test based on voice calls and data transfers are

detailed in Chapter 6.

5.3 EUT which cannot establish continuous communication

connections

It is same as the clause 5.3 of GB/T 22451.2008.

5.6 EUT classification

It is same as the clause 5.5 of GB/T 22451-2008.

6.1 General

The EUT shall comply with the minimum performance criteria as specified

below.

6.2 Performance criteria A (continuous phenomena)

The communication link shall be established before the test, AND the

communication connection shall be maintained during the test.

6.3 Performance criteria B (transient phenomena)

It shall establish the communication link before the test.

After the test, the user equipment shall not have any communication quality

degradation in the communication process which is sensible by the user.

If the entire test consists of a series of small tests, after the test, the equipment

under test shall be free of loss of user control function OR loss of stored data,

AND the communication connection can be maintained.

7.1 Disturbance measurement

Disturbance measurement items are as shown in Table 1.

8.1 Radiation spurious (enclosure port)

8.1.1 Measurement method

The measurement method of this item is carried out in accordance with the

relevant requirements of YD/T 1483.

8.1.2 Limit values

8.1.2.1 Traffic mode

The limit is as shown in Table 3.

8.2 Radiation continuous disturbance (enclosure port of

ancillary equipment)

8.2.1 General conditions

Measurements shall be made in the mode in which the EUT is operating

normally with maximum disturbance.

The measured continuous radiation disturbance shall be maximized, for

example by moving the EUT cable.

8.4 Conduction continuous disturbance (AC power

input/output port)

8.4.1 Measurement method

The measurement is carried out in accordance with GB 9254 AND the AMN is

connected to the AC power supply.

8.5 Conduction continuous disturbance (telecommunication

port)

8.5.1 Measurement method

Measurements are made in accordance with GB 9254.

9.1 Radiation disturbance immunity test (80MHz ~ 2700MHz)

9.2 Electrostatic discharge immunity test

9.2.1 Test methods and levels

The test method shall be in accordance with GB/T 17626.2.

It shall comply with the following requirements.

For contact discharge, the equipment shall be able to pass the ±2kV and ±4kV

test levels;

For air discharge, the equipment shall be able to pass the ±2kV, ±4kV and

±8kV test levels.

9.4 Conduction disturbance immunity of radio frequency field

induction (0.15MHz ~ 80MHz)
