5G R&D Test Bed, Reference Solution

Keysight’s 5G R&D Test Bed leverages Keysight’s VXG Microwave Signal Generator and UXA Series Signal Analyzer to validate the performance of 5G NR base stations (gNBs) according to the latest 3GPP 38.141 standards. This flexible solution for waveform generation and analysis offers:

Wide 2 GHz bandwidth for 5G NR multi-component carrier waveform generation
Excellent measurement system performance for 3GPP compliant 5G NR 256 QAM modulation schemes down to 1% EVM @28 GHz
5G NR band coverage of up to 44 GHz in FR2

This 5G R&D Test Bed supports Keysight’s industry-leading UXR Series Infiniium 110 GHz Real-Time Oscilloscope for direct analysis of complex 5G NR waveforms in the time domain.

It can be optionally configured using Keysight’s UXA series 110 GHz analyzer for 5G NR waveform analysis in the frequency domain. Coupled with Keysight’s N7631C Signal Studio Pro signal generation software and 89600 VSA demodulation software and Keysight’s KS8000A Test Automation Platform, this 5G R&D Test Bed provides powerful analysis and deep insights into the Over-The-Air (OTA) performance of your 5G NR gNB, MIMO phased array antennas and beamforming mmWave antenna arrays.

Standard Configurations

44 GHz 5G Test Bed, Traditional Configuration

This configuration is designed for signal creation with one or two channels, bandwidths up to 2 GHz, and frequency coverage up to 44 GHz for a variety of applications including creating wanted and interfering signals and creating 2x2 MIMO signals in a single platform. Additionally, a spectrum analyzer enables demodulation of signals up to 1 GHz in BW and traditional swept-tuned analysis of in-band and out-of-band spurious emissions with frequency coverage up to 50 GHz.

Note: the spectrum analyzer can also be ordered in models with frequency coverage up to 110 GHz to meet the 3GPP 5G NR 60 GHz spurious emissions requirements in Frequency Range 2 (FR2).

110 GHz 5G Test Bed

This configuration is designed for creating RF signals between 50 GHz and 110 GHz with bandwidths up to ~10 GHz, traditional swept-tuned measurements from 3 Hz to 110 GHz, and multi-channel demodulation of signals from DC to 110 GHz.

44 GHz 5G Test Bed with Oscilloscope for Multi-channel Analysis

This configuration uses the same source in the traditional configuration but replaces the spectrum analyzer with a high-performance oscilloscope for performing up to 4-channel time-aligned phase-coherent measurements with frequency and bandwidth coverage up to 110 GHz. The ultra-high 256 GHz sample rate combined with 10-bit vertical resolution enables demodulation fidelity comparable to traditional spectrum analyzers. This configuration enables 4x4 MIMO analysis or phase-coherent measurements of devices under tests like phased array antenna systems where evaluating performance between individual antenna elements with real-world modulated signals is important in revealing true device performance and characteristics.

Note: this configuration can also be ordered with a traditional spectrum analyzer for performing traditional swept-tuned measurements like in-band and out-of-band spurious emissions.
