6. Attenuation module host +TYPE-C line
7. Provide communication protocol: support USB and TTL serial communication
8. Input loss and standing wave parameters (refer to the measured value of vector network)
9. Maximum input power = 18dBm

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



Module Tests (By vector network analyzer):
1. Set to 0DB attenuation S parameter


2. Set to 5DB attenuation S parameter


3. Set to 10DB attenuation S parameter


4. Set to 15DB attenuation S parameter


5. Set to 20DB attenuation S parameter


6. Set to 25DB attenuation S parameter


7. Set to 30DB attenuation S parameter


Module Communication Protocol (adaptive baud rate):
1. Send attenuation coefficient command: change attenuation coefficient (the end symbol is Enter). The format is: ATT-xx.xx
2. Response value signal: The format is: ATT OK
3. Baud rate: If using USB, there is no need to set the baud rate, it is self-adaptive. If using TTL serial port, the baud rate is 9600bps.
