CT704 LANforge-Attenuator with 4 Attenuator Modules: 0.7Ghz to 6Ghz

The CT704 RF Attenuator is used to attenuate (decrease) the RF signal between wireless devices. The CT704 uses 4 of the ATS0760-95 modules from EUBUS. A summary of the technical specifications is below:

Impedance:50 Ω
Frequency Range:0.7 GHz – 6.0 GHz
Attenuation Range:0 – 95.5 dB
Attenuation Steps:0.5 dB increments
Insertion Loss:8 dB nominal, 10 dB max
Attenuation Accuracy:1-15 dB: ±1dB, 16+ dB: ±1.5dB or 4%

The CT704 may be controlled by the two knobs on the faceplate and may also 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 CT704 has no moving parts and will fit into a small travel bag or briefcase for easy portability.

The CT704 includes 8 RP-SMA Plug to RP-SMA Plug patch cables, USB Cable, and external power supply (brick).
