LANforge RF Attenuator


The LANforge RF Attenuator is used to attenuate (decrease) the RF signal between wireless devices.


The LANforge attenuator sits between two RF systems (often WiFi AP on one side and a WiFi Station on the other). The attenuator is connect by shielded RP-SMA plug cables between the attenuator and the device to be attenuated. To adjust the attenuations there are knobs on the Attenuator, or adjustment can be made by a software program on a PC connected to the Attenuator by a USB-Serial connection. The included LANforge software suite supports automated scripting as well as manual configuration of the attenuator modules.
