4 Test Conditions
4.1 General Conditions
The test shall be carried out under the conditions of normal operation of the equipment specified by the manufacturer, and the output power level of the UE shall be the level for maximum rated output power.
The test configuration shall be as close as possible to typical conditions of actual use.
When the UE has an integral antenna, the antenna in normal use shall be installed for the test, unless otherwise specified in this Part or the manufacturer declares that the antenna is removable.
If the EUT is part of the system, or is connected to ancillary equipment, the test may be performed with the minimum configuration of the ancillary equipment, and the port connected to the ancillary equipment shall be activated.
If the EUT has a large number of ports, a sufficient number of ports shall be selected to simulate actual operating conditions, and ensure that all different types of ports are included.
The EUT ports that are connected to other equipment in actual use shall be connected to ancillary equipment, associated measurement equipment or a matched load that simulates the impedance of ancillary equipment during the test. For RF input/output ports, a matched load shall be terminated.
The EUT ports that are not connected to other equipment in actual use, such as service ports, program ports or debugging ports, shall not be connected to other equipment during testing. If these ports are to be connected to ancillary test equipment in order to excite the EUT, or if the interconnecting cable must be extended, ensure that the evaluation of the EUT is not affected by the associated measurement equipment or the extension of the cable.
The ancillary measurement equipment shall be placed outside the test area. If placed in the test area, the ancillary measurement equipment shall not affect the test results of the EUT, or its influence shall be excluded.
If the EUT supports multiple operating modes, tests shall be performed in each operating mode. For example, the UE has two operating modes of voice service and data service, and both of them shall be tested.
The disturbance measurement shall be carried out at the mode under which the EUT generates the maximum disturbance during normal operation. During radiation disturbance measurement, in order to measure the maximum radiation disturbance, some necessary measures may be taken, such as moving the cables of the EUT.
The operating frequency range (FR) of the UE is shown in Table 1. For different operating frequency ranges, the test conditions for electromagnetic compatibility may be different.

4 試驗條件
4.1 通用條件
試驗應在廠家規定設備正常工作的條件下進行，UE的輸出功率電平應為最大額定輸出功率電平。
試驗配置應盡可能地接近實際使用的典型情況。
當UE具有一體化天線時，應安裝正常使用時的天線進行試驗，除非在本部分中另有規定或廠家聲明天線為可拆裝的天線。
如果EUT是系統的一部分，或與輔助設備相連，試驗可在輔助設備的最小配置下進行，與輔助設備相連的端口應被激活。
如果EUT有大量的端口，應選取充分數量的端口模擬實際情況的工作條件，并確保包含所有不同類型的端口。
對于EUT在實際使用中與其他設備連接的端口，試驗時這些端口應與輔助設備、輔助測試設備或模擬輔助設備阻抗的匹配負載相連。對于射頻輸入/輸出端口，應端接匹配負載。
對于EUT在實際使用中不與其他設備連接的端口，例如服務端口、程序端口、調試端口等，測試時這些端口不與其他設備連接。如果為了激勵EUT，這些端口要與輔助測試設備相連，或者互連電纜必須延長時，應確保對EUT的評估不因輔助測試設備或電纜的延長而受到影響。
輔助測試設備宜放置在試驗區域外，如果放置在試驗區域內，輔助測試設備不應影響EUT的測試結果或其帶來的影響應被排除。
如果EUT支持多個工作模式，則在每個工作模式下都應進行試驗。例如，UE具有語音業務和數據業務工作模式，兩種工作模式都應試驗。
騷擾測量時，應在EUT正常工作時產生最大騷擾的模式下進行。輻射騷擾測量時，為使所檢測到的輻射騷擾達到最大，可采取某些必要措施，例如移動EUT的線纜等。
UE的工作頻率范圍(FR)見表1。對于不同的工作頻率范圍，電磁兼容的試驗條件可能不同。
表1 頻率范圍的定義
名稱 頻率范圍
FR1 450MHz～6000MHz

收信機或收/發信機的收信機在進行抗擾度試驗時，離散頻率的窄帶響應應通過以下方法來判定：
—在抗擾度試驗時(見9.2和9.5節)，窄帶響應和寬帶現象都可能使受試設備出現不符合本文件規定的性能判據(見6.2節)的情況，在此情況下，應通過調整干擾信號的頻率判斷是窄帶響應還是寬帶現象；
—將測試頻率偏置±1×BWChannelMHz，重復測試，如果不符合的情況消失，則這種情況為窄帶響應；
—如果不符合的情況未消失，則可能為另一個干擾信號所引起的窄帶響應，在此情況下，將測試頻點偏置±2×BWChannelMHz，重復測試，如果不符合的情況仍未消失，這種情況為寬帶現象，即受試設備未通過測試。
窄帶響應應被忽略。
4.4 免測頻段
4.4.1 通用要求
免測頻段是指不進行射頻電磁場輻射抗擾度試驗的頻段。
輔助設備沒有免測頻段。
4.4.2 收信機免測頻段
收信機免測頻段的低端頻率是收信機接收頻段的低端頻率減去收信機支持的最大信道帶寬。
收信機免測頻段的高端頻率是收信機接收頻段的高端頻率加上收信機支持的最大信道帶寬。
