Keysight Technologies Launches First Built-in Dual Channel 44 GHz Vector Signal Generator with 2 GHz Bandwidth

High-performance VXG microwave signal generators for broadband mmWave applications for satellite and 5G communications
SANTA ROSA, California, February 19, 2019 – Keysight Technologies, Inc. (NYSE: KEYS), a leading technology company that helps other businesses, service providers, and institutions innovate to connect and secure the world, today introduces the The first dual-channel microwave signal generator to support signals up to 44 gigahertz (GHz) and 2 GHz RF modulation bandwidth, all in one instrument.
Keysight's new VXG microwave signal generators target more demanding broadband millimeter wave (mmWave) applications for satellite and 5G communications, reducing the complexity of test setup and path loss found in environments of airway tests (OTA).
Many 5G New Radio (NR) implementations make use of wider channel bandwidths and enable antenna systems that operate in mmWave frequency spectrums to support multiple input/multiple output (MIMO) as well as shaping technologies. of beam. Conformance tests indicated by 3GPP for components and other wireless network equipment intended to work on mmWave frequencies must be performed in radiated OTA test environments.
Keysight's new VXG microwave signal generators address the next frontier of cellular technology with these benefits:

  • Provide an optimized 5G NR test system configuration that enhances the generation of 44 GHz dual-channel vector signals with up to 2 GHz RF modulation bandwidth and phase coherence in a single test instrument.
  • Deliver a low path loss rate in OTA test systems, thanks to the combination of the highest output power in the industry and the performance of Error Vector Magnitude (EVM) and Adjacent Channel Relative Power (ACPR) .
  • Accelerate product development by integrating Keysight's PathWave Signal Generation, a suite of software with access to a wide range of 5G NR signals that are compliant with ever-evolving 3GPP standards for testing base stations, receivers, and mobile terminal transmitters.

“We are delighted to introduce the first dual-channel, up to 44 GHz microwave signal generator with 2 GHz bandwidth, in both modular and testbed form factors,” said Joe Rickert, Vice President of R&D for the Keysight High Frequency Measurement Division. "The VXG's ultra-low phase noise, high power output, excellent modulation, and low distortion make it an ideal signal generator for a wide range of wireless communications applications, as well as the defense, commercial, and aerospace industries."
Keysight's VXG signal generators offer designers and manufacturers of wireless equipment a wide range of advanced features, including:

  • Unmatched RF performance that optimizes measurement integrity and minimizes uncertainty for wide bandwidths at millimeter wave frequencies.
  • A new graphical user interface for 5G NR that offers a streamlined experience in creating standards-compliant test signals
  • User-focused interface (modular and multi-touch) that offers identical technical features while addressing specific needs unique to both manufacturing and R&D environments.

Keysight's 5G Waveform Generation and Analysis Benchmark Solution Optimizes the Enhanced Capabilities of the VXG Microwave Signal Generator for 5G Development Teams to Efficiently Validate New Designs in Frequency Range 1 (FR1) ) and frequency range 2 (FR2), as defined by 3GPP. The testbed solution uniquely addresses the challenges of 5G NR compliance testing and enables Keysight to rapidly integrate new technology into market-ready solutions that allow customers to act quickly and be first out to the market.
