Dual-channel 44 GHz vector signal generator, did you know?

What is a dual-channel 44 GHz vector signal generator? What does it do? February 22, 2019, Beijing - Keysight Technologies (NYSE: KEYS) today launched the first dual-channel microwave signal generator, which is available at Supports signals up to 44 GHz and 2 GHz radio frequency (RF) modulation bandwidth in the same instrument. Keysight Technologies is a leading technology company helping enterprise, service provider and government customers accelerate innovation and create a secure and connected world.

Keysight's new VXG microwave signal generator addresses the needs of very demanding broadband millimeter wave (mmWave) applications in 5G and satellite communications by reducing test setup complexity and reducing path loss in over-the-air (OTA) test environments. .

Many 5G New Radio (NR) applications are using wider channel bandwidths and active antenna arrays operating in the millimeter-wave spectrum to support multiple-input multiple-output (MIMO) and beamforming technologies. 3GPP requires compliance testing of components and other wireless network equipment deployed within millimeter wave frequencies, and this needs to be performed in a wireless OTA test environment.

Keysight's new VXG microwave signal generator supports next-generation cellular technology and offers the following key benefits:

Provide optimized 5G NR test system settings, provide up to 2 GHz RF modulation bandwidth and phase coherence capabilities through a single test instrument, and generate dual-channel 44 GHz vector signals.

It has industry-leading EVM (Error Vector Magnitude) performance and ACPR (Adjacent Channel Power Ratio) performance at high output power, providing very low path loss for OTA test systems.

Accelerate product development by integrating Keysight's PathWave signal generation software. The PathWare software suite provides access to the evolving 3GPP 5G NR standards conformance signals for base station, mobile terminal transmitter and receiver testing.

"We are very pleased to launch the world's first dual-channel 44 GHz microwave signal generator with 2 GHz bandwidth, which is also available in benchtop and modular models," said Joe Rickert, vice president of high frequency measurement R&D at Keysight Technologies. VXG "Providing low phase noise, high output power, and excellent modulation and distortion performance, it is ideal for a variety of applications in commercial wireless communications and the aerospace and defense industry."

Keysight's VXG signal generators provide wireless device designers and manufacturers with a rich set of advanced features, including:

Excellent RF performance to optimize measurement integrity and minimize uncertainty at high bandwidths at mmWave frequencies

Provides a new graphical user interface for 5G NR to provide a smooth experience while creating standards-compliant test signals

User-centered multi-touch and modular interface that delivers the same performance while meeting the unique and specific needs of R&D and manufacturing environments

Keysight's 5G waveform generation and analysis test bench solution leverages the enhanced capabilities VXG microwave signal generators provide 5G development teams to efficiently verify new technologies in 3GPP-defined frequency range 1 (FR1) and frequency range 2 (FR2). design. This testbed solution takes a unique approach to overcoming 5G NR conformance testing challenges, allowing Keysight to quickly combine new technologies with proven solutions, enabling customers to move quickly and achieve first-to-market goals. The above is the analysis of the dual-channel 44 GHz vector signal generator. I hope it can be helpful to everyone.
