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 x @4 g9 W) Z( Y
所以2307的频率可以不用测试的。

The exclusion band for immunity testing shall be calculated as follows:
: W# X$ ~- U, ~. r9 j• lower limit of exclusion band = lowest allocated band edge frequency -5 %;& x8 C* Q; l: d8 {( S- U
• upper limit of exclusion band = highest allocated band edge frequency +5 %.
. e+ B t- z0 gUsing the 2,450 MHz band as an example:
( X* w& i9 ^ h) O! a6 E) O6 O' ]& t• lower limit of exclusion band = 2 400 - 120 = 2 280 MHz;
- w* ` A+ c) l: K: Z' p• upper limit of exclusion band = 2 483,5 + 124,175 = 2 607,675 MHz; A S% S A5 G9 z1 X5 H% q! T) q
• thus the exclusion band for 2,45 GHZ equipment falling within the scope of the present document extends
