Channel Emulators

Keysight’s PROPSIM Channel Emulators enable realistic real-time performance testing of wireless devices and base stations. Users have access to 24/7 support to facilitate validating of new product releases and verify the performance of designs following implementation of new features prior to delivery.

To address complexities associated with the introduction of new 5G technologies – such as wider signal bandwidths and mmWave frequencies – Keysight launched the PROPSIM 5G channel emulators with the industry’s widest signal bandwidth and highest number of fading channels.

The first-to-market PROPSIM channel emulators offer advanced full-stack end-to-end real-world performance testing of wireless devices, network infrastructure equipment and WLAN access points in a laboratory environment.

The solutions emulate impairments of complex real-world radio channel conditions, including:

  • Dynamic multipath propagation
  • Range pathloss and blocking effects
  • Doppler from mobility and multipaths
  • Noise and synchronous programmable interference

Versatile and easy-to-use tools enable users to when test across a wide range of technologies, including:

  • 5G NR
  • LTE Pro
  • Massive MIMO
  • 3D Beamforming
  • WLAN 802.11ax
