虽然测试是参照301 489-7做的,但是实际产品是bluetooth,所以301 489-17的免测带应当适用, B) C1 L, W3 I9 f& y- c
所以2307的频率可以不用测试的。9 M4 ~! s+ X& c! H
参见下面的引用# k; M7 Z- B* g1 C9 v- N
The exclusion band for immunity testing shall be calculated as follows:
5 J7 N7 Z) g3 G7 A5 v: p/ b• lower limit of exclusion band = lowest allocated band edge frequency -5 %;
9 p! d& [! A/ V/ _. n: T0 u0 i• upper limit of exclusion band = highest allocated band edge frequency +5 %.
5 w" y: b2 |" Z7 T! @0 VUsing the 2,450 MHz band as an example:
