Please refer to Jetson TX1-TX2 OEM Wireless Compliance Guide and do the test at those labs.

But sgs is not on the list of accredited laboratories by the National Radio Commission?
what can we do?

Another option is BTL Dongguan Lab

I have also contacted this laboratory, and it is still not on the list of accredited laboratories. TX2 has CMIIT ID and FCC approval, I think there should be a software for SRRC certification

Only those labs can help, not sure why they’re not in accredited laboratories.
