测试仪表配置：
? 综合测试仪 R&S CMW500 ? 频谱分析仪 R&S FSQ
? 带阻滤波器 主要作用是衰减工作频带内的发射信号，降低输入到频谱分析仪的
混频器的输入端口信号强度，防止输入到频谱仪中的信号过大，导致频谱仪过载（overload，频谱仪动态范围不够），进而失真导致结果出错；同时防止输入到频谱仪中的信号强度大，将频谱仪的底噪抬高将杂散信号淹没，导致的测试结果不正确；还可以防止大的发射信号与频谱仪产生交调，引入额外的频谱杂散分量，影响测试结果的真实性。

6. 测试步骤
1. 按照上图搭建测试环境。
2. 在CMW 500上按照Table 6.6.3.1.4.1-1，设置RB数目和调制方式，并让UE以最大发射功率
发射。
3. 使用频谱仪进行杂散测试
1） 根据不同的测试频段，设置起始与终止频率，并设置相应的RBW 和VBW。
在设置频率时，如果遇到UE的发射频段，是需要将其规避的。规避的范围是：上下边带频率的基础上+/-(ΔfOOB+MBW/2), MBW就是Table 6.6.3.1.3-2中的Measurement Bandwidth测试带宽，即频谱仪的解析带宽，也就是RBW。 如B3，20M 带宽，19575频点，载波频率为1747.5MHz，信道实际带宽为1737.5M~1757.5M，ΔfOOB为25M，MBW为1M,实际测试杂散的保护带为1712MHz～1783MHz；
2） 设置线损: 在频谱仪上AMPT软键下设置。
3） 按下SWEEP软建，设置sweep time 为6s左右，sweep point为9000
4） 按下Trace软建，设置Trace为Max hold，Max hold为最差状况，如果Max hold没有
问题的话，肯定可以通过的，检波方式为RMS；如果Max hold方式不同通过的话，需要对不通过的点采用手动验证，trace方式改为clear/write，这样还是不过的话，就是杂散招标了。
5） 更改信道，重复上述操作步骤，直至3个信道都测试完成。 7. 注意事项
1）认证机构设置：检波方式为RMS检波、trace方式为clear/write
2）目前，实验室没有10M以上的带阻，所以LTE在测试杂散的时候一般采取的方法是： 5M（带阻调到-40一下）、10M（带阻调到-20一下）加入带阻，15M、20M不加入；
但是，由于带阻是频繁切换的，自动化又是连续的，频繁调带阻很费时间，所以，
目前也可以采取所有带宽都不加带阻的方法，一气儿用自动化测完，但不加带阻测
试时，可能会出现部分频点失真如果有FAIL点，在通过加入带阻滤掉载波，使仪器 的动态范围可以满足测试，手动验证即可。
3）测试需重点关注的就是测量带宽，这里的测量带宽指的是频谱仪的解析带宽，即RBW。 不同频率范围所对应的值是不同的，需注意，否则，手动验证时会影响测试结果。
4）需要测量的插损：
综测仪到UE之间的插损
频谱分析仪到UE之间的插损
二、UE共存带内的杂散辐射带（6.6.3.2）
1. 指标含义
UE共存发射杂散是指：在协议定义内的共存的频带系统内产生的一些有特殊要求的发射机传导杂散。 2. 测试目的
UE的杂散可能落到其他共存系统的接收频段内，造成其他共存系统的干扰，为了验证UE发射的信号不能引起共存系统不可接受的干扰而启动该项测试。 3. 测试配置
