YD/T 1595.1-2012Requirements and measurement methods of electromagnetic compatibility for 2GHz WCDMA digital cellular mobile telecommunications system - Part 1: user equipment and ancillary equipment (English PDF)

3.1 Terms and definitions

For the purpose of this document, the following terms and definitions shall apply.

3.1.1

International mobile telecommunication-2000 (IMT-2000)

It is the third generation mobile telecommunication system, which can access fixed

telecommunication network (e.g. PSTN, ISDN, IP, etc.) business and other business

provided for mobile users via one or more radio links.

3.1.2

Universal Terrestrial Radio Access (UTRA)

It is a particular radio access network defined in 3GPP Specification.

3.1.3

User Equipment (UE)

It is an entity which can access UTRA business via one or more radio interfaces. When

accessing UTRA business, this entity can be either static or mobile in the UTRA business

area; this entity can serve one or more users at the same time.

3.1.4

Idle Mode

It is a state of user equipment, in which user equipment has been started but without RRC

connection.

3.1.9

Camped On a Cell

It means that UE completes the selection or reselection for a cell and is now in the idle

mode. UE monitors system information and paging messages.

Note. The business may be limited; PLMN (Public Land Mobile Network) may not know which cell has

been selected by UE to camp on.

3.1.10

Spurious Emissions

The disturbances on the discrete frequency except carrier frequency and the sideband

related to normal modulation, including conducted spurious emissions and radiated

spurious emissions.

3.2 Abbreviations

The following abbreviations are applied in this document.

4.1 General Conditions

EUT shall be tested in normal testing environment which shall be recorded in the report.

If EUT has separable integral antennas, unless otherwise specified in this Part, it shall be

equipped with antennas to conduct the test the way it is normally used.

The test arrangement shall be as approximate to normal or typical actual running state as

possible.

4.2 Test Arrangement

During the test, frequency of RF signals shall be selected from appropriate UTRA absolute

radio frequency channel number (UTRA ARFCN).

4.2.3 Test Arrangement of Receiver Input Port

SS shall be placed outside the testing environment.

The frequency of useful RF input signal for providing telecommunication links shall be

selected through correct UTRA ARFCN, unless otherwise specified in other Parts of this

Standard, it is advisable to select the UTRA ARFCN corresponding to the center

frequency of the operating frequency band.

4.6 Immunity Test Conditions and Arrangement

6.4 Performance criteria C (discontinuous phenomenon)

In test, performance is allowed to have degradation, and function can be lost; EUT sender

shall not generate unconscious launch under idle mode. After test, function can be

recovered by operator. After recovery, performance is not degraded and EUT can work

normally.

7.1 Disturbance measurement

Items for disturbance measurement are shown in Table 1.

8.1 Antenna's port (conducted spurious)

Measurement method of this item shall be carried out according to relevant contents of

YD/T 1483.

8.2.2 Limit value

8.2.2.1 Business mode

Limit value is shown in Table 5.

8.3 Chassis' port of auxiliary equipment

8.3.1 General conditions

Measurement shall be carried out under such mode as EUT works normally to generate

the maximum disturbance.

It shall make radiation continuous disturbance measured up to the maximum value, such

as cable passing through mobile EUT.

8.4 Telecom's port

8.4.1 Measurement method

Measurement shall be carried out according to GB 9254.

8.5 DC power input/output port

8.5.1 Measurement method

Measurement shall be carried out according to GB 9254.

When the results meet average limit value by using quasi-peak detection measurement, it

shall be considered it meets requirements of 2 limit values, and it's unnecessary to have

average value detection measurement.

frequency.

8.6 AC power input/output port

8.6.1 Measurement method

Measurement shall be carried out according to GB 9254.AMN is connected with across

current power.

9.1 Electrostatic discharge immunity test

9.1.1 Test method and grade

Test shall be carried out according to GB/T 17626.2.

It shall meet the following requirements.

9.12 Performance criteria

Performance criteria in 6.3 of this Part are applicable to this term.

9.2 Radiation disturbance immunity test (800MHz ~ 2.7GHz)

9.5 Conducted disturbance immunity test of radiofrequency field sensitivity

9.5.1 Test method and grade

When the connection cable for AC power port/signal/telecom/control port and DC power

port of fixed, on-board and auxiliary equipment exceeds 3 meters, this test item shall be

carried out.

9.6 Power frequency magnetic field immunity test

9.6.1 Test method and grade

This test item is only applicable to EUT with device sensitive to magnetic field. The test

method is shown in GB/T 17626.8.

Test grade is 3A/m.

9.7 Immunity test of voltage dips, short interruption and voltage change

9.7.1 Test method and grade

9.7.2 Performance criteria

9.7.2.1 Across current power supply performance criteria

For voltage dips that power supply voltage drops 100% and time duration is 10ms; power

supply voltage drops 100% and time duration is 20ms; power supply voltage drops 30%

and time duration is 500ms, performance criteria B in 6.3 of this Part are applicable to this

term.
