Highlights

The S8825A Satellite and Aerospace Channel Emulation Toolset is based on Keysight's F8800A F64 or F8820A FS16 PROPSIM channel emulator. The toolset enables satellite, aerospace, and airborne radio system performance validation under uncompromised, coherent real-world complex 3D propagation conditions.

Today’s space applications introduce new advanced technologies including wider signal bandwidths, higher frequencies, and beamforming. To address associated complexities, Keysight introduced the first-to-market channel emulation solution that offers the widest signal bandwidth and the highest number of fading channels to test performance of 5G NTN aerospace and terrestrial links in a single unit.

Performance validation of a high velocity aerospace environment requires a test environment that emulates high Doppler frequencies and supports long delays, both common in satellite links. The PROPSIM Channel Emulation Solution allows users to create high-velocity test environments that meet the highest requirements. With the solution, users can create test scenarios using PROPSIM tools or import scenarios from third-party tools. By using a file-based emulation of test scenarios, Keysight’s PROPSIM Channel Emulation Solution assures accurate, realistic and repeatable test conditions for wireless aerospace, telemetry, satellite and high mobility broadband communications applications.

Demand of the wider bandwidths push the satellite networks into higher frequency bands. The latest 3GPP 5G NTN introduces the K-band, 20/30 GHz frequency range, which is fully supported with the S8825A solution. Added with the new M1742A K-band Transceiver, with frequency range of 10 to 32 GHz, S8825A supports all the new requirements of the future wideband NTN services.
