Product Overview
4-channel programmable RF attenuator — 50 MHz to 8 GHz, 0.25 dB steps
4-channel attenuator with extended frequency range and 0.25 dB steps.
The CT-714b refines the CT-714 with a wider 50 MHz – 8 GHz frequency
range and finer 0.25 dB attenuation steps — useful when you need
precise path-loss control for Wi-Fi 6 GHz, cellular or precise
compliance testing.
Same compact form factor and software-only control as the CT-714, with
the same 4-channel layout (8 SMA connectors). Drives directly from
LANforge scripts and the JSON API.

Typical Use Cases
- •Wi-Fi 6 / 6E / 7 path-loss sweeps with fine 0.25 dB resolution.
- •Cellular and Bluetooth coexistence testing across the full 50 MHz – 8 GHz range.
- •Roaming, handoff and Rate-vs-Range automation.
- •Repeatable RF conditions for compliance and certification work.
/// Hardware Specifications
- 4 channels, 8 SMA connectors (4 in / 4 out).
- Attenuation range: 0 – 95 dB in 0.25 dB increments.
