System - Part 1: User Equipment and Ancillary Equipment
1 Scope
This Part of GB/T 19484 specifies the electromagnetic compatibility requirements for user
equipment (UE) and ancillary equipment of 800 MHz and 2 GHz cdma2000 digital cellular
mobile telecommunications system, including measurement methods, limits and performance
criteria, etc.
This Part is applicable to CDMA, CDMA1X, cdma2000 and cdma2000 HRPD user equipment
that transmits and receives voice and / or data, including portable and vehicle-mounted user
equipment, as well as user equipment powered by AC power and used in fixed locations, etc.

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.
