CC2540 RF性能测试数据

1、测试的文档可以看这边： www.ti.com.cn/.../swra370.pdf
2、很有可能是晶振的问题
3、The BT Sig Spec calls for testing sensitivity with a PER limit of 30.8%. This translates to a BER of 0.1% while using the max BLE packet size (37 octet payload).

1.测试文档我看过，这里面并没有测试结果的数据，可不可以提供有测试结果的数据，TI demo测试的数据也可以啊

3.这个PER和BER的相关文档介绍有吗

You can calculate the BER directly from the PER. The BT Sig Spec calls for testing sensitivity with a PER limit of 30.8%. This translates to a BER of 0.1% while using the max BLE packet size (37 octet payload). I would recommend just testing PER with a pass/fail threshold of 30.8%.

The calculation is as follows: Assume a model receiver where all the bits have the same error probability and bit errors are statistically independent events. If any bit in the packet, except for the preamble, is incorrect, the packet will be lost, as the access address has to be error-free if the packet is to be received, and the header and payload is protected with CRC. This means that 368 bits have to received error-free for the maximum length packet to be received correctly. If the bit error rate is 0.1%, or 0.001, this means that the packet error rate is:

1-((1-0.001)^368) = 0.308010241105056

TI的规格书就是最终的测试报告了。都是最终特征测试之后输出的统计结果。
