2. Features of products

2.1, gain automatic linkage function:The automatic detection device receives a signal, automatically sets the uplink gain of the device after tracking the downlink gain of the device, and always keeps the gain of the uplink of the device less than the signal attenuation to the base station, thereby ensuring that the mobile network is not interfered and increasing the number of devices used by the base station.

2.2. Self-excitation detection function: The device supports automatic detection of the isolation function of the transceiver antenna, supports automatic adjustment of the device gain function, supports the status indication function, and supports the device protection function, so as to avoid network interference caused by the introduction of the device.

2.3, digital automatic output power adjustment function:Ensure that the device maintains a stable output power when the external signal fluctuates. Meet the coverage requirements.

4. Introduction of indicator light of equipment

Indicator light identification	Indicator status	Description
Power Indicator POWER	The light is always on	Power on equipment
Power Indicator POWER	Light out	Equipment power failure
Lower output power indicator Output Power(DL)	The light is always on	Equipment full power output Pmax ± 2dBm
	Light flashes	Output power in (Pmax-3 ~ Pmax-15)± 2dBm
	Light out	Output power ≤(Pmax-16dBm)± 2dBm
Isolation indicator Isolation red and green double color lamp	The light is always on	Isolation is too small, enter the equipment protection function
	Light flashes	Poor isolation
	Light out	Good isolation
TDD Sync Indicator RF_Switch	The light is always on	On synchronization
TDD Sync Indicator RF_Switch	Light out	Step-out
Precautions for use: in order to ensure normal communication in actual use of this equipment, it is necessary to ensure that the "Isolation" indicator lamp appears "off" and the "RF_Switch" indicator lamp needs to be "always on".
