Channel Emulators

PROPSIM solutions are designed for advanced full-stack end-to-end real-world performance testing of wireless devices, base station network infrastructure and WLAN access points and devices within a laboratory.

Solution supports quick and easy testing of base station and mobile device key performance indicators such as data throughput, beam management, latency, stability with mobility handovers. Versatile and complex test scenarios such as multi-user and multi-cell configurations across frequency bands and radio access technologies are easily defined by the user with easy to use industry-leading PROPSIM test scenario building software.

PROPSIM channel emulation solutions emulate accurately characteristics of real-world radio channel conditions for improved test coverage and quality. PROPSIM solution enables users to validate new product releases and continuous implementation of new features to verify performance prior to delivery with 24/7 testing support.

The industry’s leading chipset, device and base station manufactures use PROPSIM solutions to verify that new products and new software releases meet set quality metrics prior the field deployment. Solutions support 3GPP, 802.11 WLAN and Tier-1 Mobile Network Operator test requirements.

5G is introducing new advanced technologies including wider signal bandwidths, mmWave frequencies and Massive MIMO with hybrid beamforming. To address associated complexities, Keysight was first to market with a 5G NR-ready channel emulation solution that offers the widest signal bandwidth and highest number of fading channels. PROPSIM 5G Channel Emulation Solution is designed for end-to-end realistic and repeatable real-world performance testing in the lab. It supports all 5G NR key technical requirements, including signal bandwidths up to 400MHz, carrier aggregation schemes continuous up to 1.2GHz and non-contiguous up to 16CC. The solution supports massive MIMO channel emulation with radio channel models defined in TR38.901 for both conducted and Over-The-Air (OTA) testing across sub 6GHz and mmWave frequencies.

PROPSIM F64 RF fader platform seamlessly integrates with Keysight’s 5G network emulation solution portfolio to emulate complex fading test scenarios coherently with protocol signaling for complete end-to-end device performance testing in sub 6GHz and mmWave bands.

PROPSIM Channel Emulation Solutions are versatile and easy-to-use in a wide range of applications including 5G NR, LTE Pro, massive MIMO and 3D Beamforming testing, WLAN 802.11ax MIMO and beamforming testing, Device MIMO OTA testing, Virtual Drive Testing, Aerospace & Satellites radio testing and MANET radio testing.
