CT714b LANforge-Attenuator with 4 Attenuator Channels: 50 MHz - 8 GHz


The CT714b RF Attenuator is used to attenuate (decrease) the RF signal between wireless devices. A summary of the technical specifications is below:

Max RF Power:+28 dBm
Impedance:50 Ω
Frequency Range:50 MHz – 8.0 GHz
Attenuation Range:0 – 95 dB
Attenuation Steps:0.25 dB increments

The CT714b may be controlled through software access over the USB-Serial port. The included LANforge software suite supports automated scripting as well as manual configuration of the attenuator modules.

The CT714b is a test tool and should be used in an RF enclosure to prevent un-intended RF interference with other equipment.

The CT714b has no moving parts and will fit into a small travel bag or briefcase for easy portability.

The CT714b includes 8 SMA-Male to SMA-Male semi-rigid RF cables, and a USB Cable for both management and power supply.

Example Network Diagram


The LANforge attenuator sits between two RF systems, often a WiFi AP on one side and WiFi Station on the other. The attenuator and WiFi stations are connected by shielded SMA-Male cables. Adjust the attenuation as desired either with the LANforge GUI or direct access over serial.

Quick Start Guide

  1. Connect the CT714 to a Linux system running LANforge with the included USB cable. The USB cable allows control of the CT714. The USB cable also provides power so no other power cable is required.
  2. Connect the attenuator pairs: One side to one system and the other side to another system or antennas.
  3. Open a LANforge GUI and connect to the Linux system with the CT714.
  4. In the Attenuator tab, you should see the CT714 device. Modify it to set attenuation values manually and/or configure a script to change attenuations automatically.
  5. One useful feature for the CT714 is the Rate vs Range test in Chamber View. The second screenshot below shows the possible options this feature gives. For more information, please see Testing Rate vs Range throughput for a WiFi Device.
