中国无线电型号核准认证（SRRC）办理流程
准备资料：包括企业营业执照、产品说明书、电路图、样机（通常2-3台）等。
提交申请：通过工信部型号核准系统提交，审核通过后进入检测阶段。
实验室测试：由SRMC等认可实验室完成，测试项目包括频率范围、发射功率、杂散发射等。
审核发证：测试合格后提交工信部审核，通过后颁发SRRC证书。
SRRC认证测试方法
核心测试项目：
频率范围：验证设备发射频率是否与申报一致。
发射功率：测量峰值和平均功率，确保不超过限值。
杂散发射：检测谐波、带外发射等干扰信号。
调制特性（如EVM）：评估数字调制质量。
测试方式：包括辐射（天线发射）和传导（射频接口）测试。

Process for China Radio Model Approval Certification (SRRC)
Preparation materials: including business license, product manual, circuit diagram, prototype (usually 2-3 units), etc.
Submit application: Submit through the model approval system of the Ministry of Industry and Information Technology, and enter the testing stage after approval.
Laboratory testing: Completed by accredited laboratories such as SRMC, the testing items include frequency range, transmission power, stray emissions, etc.
Review and certification: After passing the test, submit it to the Ministry of Industry and Information Technology for review, and issue an SRRC certificate upon approval.
SRRC Certification Testing Method
Core testing items:
Frequency range: Verify whether the device's transmission frequency is consistent with the declared frequency.
Transmission power: Measure peak and average power to ensure it does not exceed the limit.
Stray emission: detects interference signals such as harmonics and out of band emissions.
Modulation characteristics (such as EVM): Evaluate the quality of digital modulation.
Testing methods: including radiation (antenna emission) and conduction (RF interface) testing.
