4 Test Conditions
4.1 General Conditions
EUT shall be tested under normal test environment. The test conditions shall be recorded in the
report.
When EUT has a detachable antenna, unless otherwise specified in this Part, the antenna shall
be mounted in the same mode as in normal use for the test.
The test layout shall be as close as possible to normal or typical actual operating conditions.
If EUT is part of a system or is connected to ancillary equipment, then, during the test, EUT
shall be connected to the minimum typical configuration of ancillary equipment, and the ports
connected to the ancillary equipment shall be activated.
During the test, the operating mode and configuration shall be accurately recorded in the test
report.
If the equipment has a large number of ports, a sufficient number of ports shall be selected to
ensure that actual conditions can be simulated and that different types of ports can be tested.
Before the test, UE shall be in the maximum power transmission state, and its maximum total
radiated power value shall be confirmed. The test method shall refer to YD/T 1484, and the test
results shall be recorded in the test report.
4.2 Test Layout
Under full-rate transmission conditions, EUT establishes a communication connection with a
suitable base station simulator. The base station simulator shall be outside the test environment.
The immunity test for mobile and handheld radio terminals needs to be separately conducted in
the following two modes:
---business mode;
---idle mode.
When EUT establishes business mode, it is necessary to use the loopback service option to
establish a connection, and satisfy the following conditions:
---EUT transmits at maximum power;
---Prohibit “variable rate data transmission”;
---EUT is transmitting at maximum data rate.
In idle mode, EUT needs to satisfy the following conditions:
---EUT receiver is set to CDMA single mode;
---The test system shall simulate a base station and establish a paging channel (either a
fast-paging channel or a forward common control channel) and a broadcast control
channel in a carrier frequency. UE is already synchronized and can respond to the base
station’s paging signal. UE shall not initiate calls, re-register or send information.
There shall be adequate measures to ensure that anti-interference RF signals will not be applied
to the measurement equipment.
4.2.1 Test layout of transmitter input terminal
Through an appropriate normal modulation signal generated by an internal or external signal
source, enter the transmitter input terminal. The external signal source shall be located outside
the test environment.
SS shall ensure that EUT continuously transmits.
4.2.2 Test layout of transmitter output terminal
SS shall be placed outside the test environment.
If EUT contains an external 50  RF antenna port, and in actual application, this port is usually
connected through a coaxial cable, during the test process, the useful signal for establishing a
communication connection shall be fed out from this port through the coaxial cable.
If EUT contains an external 50  RF antenna port, and in actual application, this port is usually
not connected to a coaxial cable, or if EUT does not contain an external 50  RF antenna port
(for example, the integral antenna equipment), then, during the test process, the useful signal
for establishing a communication connection shall be fed out through the antenna within the
test environment.
During measurement, the influence of disturbance signals on the measurement equipment shall
be avoided.
4.2.3 Test layout of receiver input terminal
SS shall be placed outside the test environment.
The useful RF input signal frequency that provides the communication link is selected by
setting the correct UTRA ARFCN, unless otherwise specified in other parts of this Standard,
during the test, the UTRA ARFCN corresponding to the center frequency of the operating
frequency band shall be selected.
If EUT contains an external 50  RF antenna port, and this port is usually connected through a
coaxial cable, the useful signal for establishing a communication connection shall be fed in
from this port through the coaxial cable.
If EUT contains an external 50  RF antenna port, and this port is usually not connected to a
coaxial cable, or if EUT does not contain an external 50  RF antenna port (for example, the
integral antenna equipment), then, the useful signal for establishing a communication
connection shall be fed in through the antenna within the test environment.
During measurement, the influence of disturbance signals on the measurement equipment shall
be avoided.
In the immunity test, the electrical level of the useful RF input signal providing the
communication link shall be 40 dB above the reference sensitivity level of EUT. The electrical
level of the input signal shall be recorded in the test report.
In the disturbance measurement, the electrical level of the useful RF input signal shall not
exceed the reference sensitivity level by 15 dB. The electrical level of the input signal shall be
recorded in the test report.
4.2.4 Test layout of receiver output terminal
For the voice function of the equipment, the audio output of the receiver shall be connected
through a non-conductive acoustic tube to an audio distortion analyzer or other similar
measurement instruments located outside the test environment. For situations where the non-
conductive acoustic tube cannot be used, other methods can be adopted to connect the output
of the receiver to an audio distortion analyzer or other similar measurement instruments, and
this shall be recorded in the test report.
For the non-voice function of the equipment, the output signal of the receiver shall be connected
through a non-conductive method to the test equipment located outside the test environment. If
the receiver has a receiver output connector or port, then, the cable shall be connected as in
normal operation of EUT to the test equipment located outside the test environment.
Measures shall be taken to minimize the influence of coupling on test results.
4.3 Test-exempt Frequency Band
The test-exempt frequency band refers to the frequency band exempted from the radiated
immunity test.
There is no test-exempt frequency band for ancillary equipment.
4.3.1 Test-exempt frequency band of transmitter
The test-exempt frequency band of transmitter is the center frequency of the current radio
frequency transmission carrier frequency  2.5 times the channel bandwidth.
4.3.2 Test-exempt frequency band of receiver
The low-end frequency of the test-exempt frequency band of the receiver and the receiving part
of the receiver / transmitter is the low-end frequency of the receiving frequency band of the
