5G Channel Sounding, Reference Solution

Keysight’s 5G Channel Sounding Reference Solution consists of multiple hardware and software elements to provide wideband signal generation. This solution helps research engineers to advance 5G channel modeling at mmWave frequencies.

The test platform addresses the challenges posed by mmWave frequencies and wide analysis bandwidths for 5G channel capture and characterization. Researchers can determine the properties of a radio channel by understanding the impact of path loss, Doppler effect, and other issues on signal transmission. The solution easily scales up by adding Keysight up/down converters and digitizers.
