3. 配置.

3.1 頻帶

There are three frequency bands to be selected

——800MHz/1.4GHz/2.4GHz. You can choose the

suitable frequency band according to local regulations.

The specific frequencies for each band are as follow:

800兆赫：806～825MHz；

1.4千兆赫：1427~1447MHz；

2.4千兆赫：2408～2480MHz；

3.2 帶寬

There are four BW to be selected——3MHz/

5MHz/10MHz/20MHz. The greater the BW, the more

data can be transmitted, but the weaker the

抗干擾. In Fixed frequency mode, M50/M51 will have

more frequency to fix with small BW.

Additional, there is a shortcut key on M50/M51.

You can change BW easily. While NB is narrow band，

and WB is wide band. For both the air and ground unit,

the shortcut key should in the same place. 除此以外, they can not link.

3.3 射頻功率

M50/M51 has three levels of power to choose.

In order to cause interference between devices, 請

select the appropriate transmission power. The specific

RF功率值如下：

1-低：15dBm的；

2-中：20dBm的；

3-高的：25dBm的。

3.4 跳/固定模式

有兩種模式可以選擇 -

/固定. 在跳躍模式, M51可以自動調整

有乾擾的頻率. 在固定模式下,

該設備已固定為特殊頻率 . 所以一個
