与发射机杂散一样，这里不在赘余
四、 发射机互调（6.7）
1. 指标含义
在与UE发射频段临近范围内的干扰信号，会和UE发射机发射出来的信号进行调制，产生交调产物，这些产物可能会落到UE或其他终端的接收频段内，对他们产生影响。
2. 测试目的
如果发射机互调产物太大，落到接收机接收频段内，会使底噪抬高，降低灵敏度，影响终端接收机性能，所以要进行该项目的测试。 3. 测试配置

6. 测试步骤
发射机交调衰减指发射机发射功率和交调产物功率之比,例如UE发出的最大功率为23dBm(测试时一般会回退3dB)， 交调产物是-20dBm， 两者相差-43dBc, 即发射机交调衰减。
1．在综测仪CMW 500 上设置：
在LTE Signaling界面按Table 6.7.4.1-1设置 Uplink的RB数目，调制方式，补线损，发射机以最大功率发射（一般会回退3dB，频谱仪或是功分器将两路和为一路的时候会有3dB的抬升，以频谱仪的抬升为主要原因），注册连接 2．测量UE的平均功率，在频谱仪上读出不加干扰源时的UE的功率 3．设置干扰信号功率及频点
a． 设置干扰源的中心频点：
如上表，以以B3，20M带宽为例，在发射上行中心频点1747.5MHz的基础上左右偏移20MHz（之后偏移40MHz），即1767.5MHz和1727.5MHz上加入干扰单音信号。 b． 如上表设置功率为-40dBc，dBc 指和UE最大发射功率(一般回退3dB，为20dBm)之
间的比值，这样的话，单音信号源的功率大小为-20dBm。
4. 用频谱仪进行互调产物测试，读出交调产物的功率，在与步骤2中的功率进行比较， 看是否满足协议要求，上表协议要求中的Intermodulation Product，指交调产物与UE最大发射功率之间的差值。
5．将干扰源频率设为第二个偏置进行重新测试
7. 注意事项
1）.在测试发射机交调时要注意信号源的所加入的值的计算，此值的大小取决于当时在频谱仪上测量出的UE最大功率发射时所测量的功率值，然后根据表5的要求算出所加的单音干扰信号的大小。同样在测试交调产物时也是根据当前测量出的最大功率来确定交调衰减值的。
2）.对于交调产物大小的测量，主要通过频谱仪完成，此时频谱仪应该设置为对应测量OBW的测试界面测量交调产物的大小。
3）.目前自动化工程并不支持该项目测试，由于风险小，而且与芯片相关，所以一般实验室里都不去测试，如果不放心，可以手动验证一下。
接收机指标
-----ACS，带内，带外，窄带阻塞等测试就目前的测试环境来看是要加入带阻的，若加了带阻还是不能过，就是问题。注意带阻的使用范围：3GHz以下请使用带阻，3G以上请使用高通。
一、邻道选择性（ACS）（7.5）
1. 指标含义
在UE接收频段的指配信道邻近存在另一个LTE信号，就叫邻道选择性。 2. 测试目的
考虑加入了邻道干扰时，验证UE接收机接收选择性能和抗干扰能力，看接收机的实际接收能力如何。 3. 测试配置
