CC1200 ASK连续接收模式

Other Parts Discussed in Thread: CC1200DK, CC1200

背景:连续接收915MHz的ASK调制信号

硬件:CC1200DK

测试条件:使用smartRF studio 7配置CC1200

4.8k ook默认配置,与915MHz信号源同轴相连。改频点到915MHz其余不变,进入continue RX模式,未打开信号源的时候发现串口输出如下:

全部都是噪声

谁能解释一下RSSI offset=108是在哪里设置的呢?此时AGC_adj是00啊?

我看到有相关的问题,在如下链接

为了屏蔽噪声的干扰,有人建议打开CS,并设置好门限。但我发现在continue RX模式下,smartRF studio 7不能触发接收呢,非常奇怪。有没有碰到类似问题的工程师呢?
