Keysight Channel Emulators

This video introduces Keysight Channel Emulation solutions, designed to enable end‑to‑end real‑world testing of wireless devices, network infrastructure, and WLAN access points within a controlled laboratory environment. These solutions combine high‑performance channel emulator hardware with specialized software toolsets to accurately recreate mobility, fading, interference, congestion, beamforming conditions, handovers, and real‑world wireless propagation scenarios.

Keysight channel emulator hardware delivers scalable and repeatable RF testing across sub‑6 GHz and mmWave frequencies, supporting up to 64 coherent channels, 1.6 GHz of instantaneous bandwidth, multiple MIMO topology configurations, and frequency ranges up to 29.5 GHz. This flexibility makes the platform suitable for 5G NR, LTE, WLAN, NTN, tactical radio, mesh networks, and future next‑generation wireless technologies.

A suite of software toolsets expands the capability of the emulator hardware. The General Channel Emulation Toolset supports standards‑based and customizable RF scenarios using Keysight Channel Studio software. The MIMO OTA Emulator Toolset provides realistic testing for 5G MIMO devices, emulating multi‑path propagation and spatial channel characteristics. The RF Field‑to‑Lab Toolset captures real‑world RF environments, including interference, fading, and degraded coverage, and brings them into the lab for debugging, regression, and repeatable validation. The Satellite & Aerospace Toolset enables accurate link‑performance and protocol testing for satellite and airborne communication systems. The MANET Channel Emulation Toolset supports flexible, software‑configurable mobility, terrain, and multi‑node topologies for tactical radio, mesh, and autonomous‑network performance evaluation.

Channel emulation systems may also be paired with Keysight anechoic test chambers, enabling shielded, quiet test environments suitable for MIMO OTA, beamforming, and antenna validation. Together, these capabilities provide a comprehensive platform for validating wireless device and system performance under realistic, repeatable, and controlled RF conditions supporting both R&D and high‑performance production testing.
