Features:
- All aluminum alloy, split cavity design
- Support TYPE-C port power supply + communication; Supports for TTL serial communication
- 1.3 inch full color TFT + button control
- Bidirectional communication through RF port, without distinguishing between input and output
- Mainly used in fields where amplitude output needs to be controlled on RF and IF links. This programmable attenuator has advantages such as wide frequency range, support for multiple communications, low power consumption, high attenuation accuracy, small attenuation step, fully shielded multi cavity design, flat curve, and good isolation.

Module Communication Protocol:
- Send attenuation coefficient command: Change the attenuation coefficient (ending with "Return/n/r"); format: att-xxx.xx
- The response value signal format is: attOK
- When using TTL serial communication, the baud rate is 9600
- Read data format: READ (Return/n/r)
- USB communication uses STM32F4 virtual serial port, without setting baud rate.

Specification:
- Power supply: +5V (Type-C power supply)
- Input and output impedance: 50ohm
- Output interface: SMA female connector
- Minimum attenuation step: 0.25DB
- Maximum input power: 30dBm (1W)
- Size: L x W x H = 6.8 x 4.8 x 2.5cm
- Weight: 120g
- Communication protocol: support USB and TTL serial port communication simultaneously

Package Included:
- 1 x Attenuator Module
- 1 x Type-C Cable
