Furthermore, a gain value may be sent which may be used to control a variable gain amplifier (VGA) within the transceiver during 8-PSK operation.

而且，可以发送增益值，它可用来控制在8-PSK操作期间的收发信机中的可变增益放大器（VGA）。

Then after a variable gain amplifier, After A / D conversion and through the microcontroller serial digital data to the ARM within the main control panel for processing.

然后经过一级可变增益放大器，在经过A/D变换，通过单片机串口将数字数据传输到ARM主控制板内进行处理。
