Keysight Technologies has launched the first dual-channel microwave signal generators that support a 2GHz modulation bandwidth in bands up to 44GHz in a single instrument for 5G testing. 

The VXG microwave signal generators are aimed at wideband millimeter wave (mmWave) applications for 5G and satellite communications by decreasing test set-up complexity and reducing path losses introduced in over-the-air (OTA) test environments.

Many 5G New Radio (NR) deployments have wider channel bandwidths and active antenna arrays operating in mmWave frequency spectrum to support multiple-input and multiple-output (MIMO), as well as beamforming technologies. 3GPP mandated conformance testing of components, and other wireless network equipment aimed for deployment in mmWave frequencies, need to be performed in radiated OTA test environments. 

The VXG signal generators provide a 5G NR test system setup leveraging dual-channel 44 GHz vector signal generation with up to 2 GHz RF modulation bandwidth, and phase-coherent capability in a single test instrument with low OTA test system path loss resulting from the industry’s highest output power versus error vector magnitude (EVM) and adjacent channel power ratio (ACPR) performance. The PathWave Signal Generation software suite gives access to a wide range of evolving standards-compliant 3GPP 5G NR signals for testing base stations, mobile terminal transmitters and receivers.

“We are excited to introduce the world’s first dual-channel 44 GHz microwave signal generator with 2 GHz bandwidth, in both benchtop and modular form factors,” said Joe Rickert, Keysight Vice President, High Frequency Measurement R&D. “The VXG’s low phase noise, high output power, excellent modulation, and distortion performance make it an ideal signal generator for a wide breadth of applications in wireless communications, for commercial and aerospace defense industries.”

Keysight’s 5G waveform generation and analysis testbed uses the VXG for 5G development teams to efficiently validate new designs across both frequency range 1 (FR1) and frequency range 2 (FR2) as defined by 3GPP. The testbed solution uniquely addresses the challenges of 5G NR conformance test and enables Keysight to quickly integrate new technology into designs.

The VXG is avilable in a PXI format or standalone generator with integrated touchscreen.
