Multichannel Vector Signal Generator – Calibratable Mode Testing
Demos
This video demonstrates the advanced capabilities of the Keysight compact multichannel vector signal generator designed for phased array antenna testing. Engineers can see how the device enables precise phase-coherent switching and synchronous pulse sweeps across up to four channels, each supporting independent frequency and power control.
The demonstration covers the setup process, including trigger configuration via LAN, uploading preconfigured pulsed list sweep files, and enabling RF output. You will see how the generator produces perfectly synchronized double pulse patterns, with the ability to introduce relative delays and maintain repeatable phase relationships even when switching frequencies and power levels.
The phase memory feature ensures absolute phase restoration, which is critical for applications such as beamforming and calibration in 5G networks and other high-precision signal environments.
The video highlights the technical challenges of antenna testing, such as the need for accurate beamforming calibration and the risks associated with phase or amplitude mismatches. It shows how the Keysight signal generator’s features help overcome these issues to maintain signal integrity and minimize interference. You will gain a clear, practical understanding of how multichannel generators with phase-coherent switching can enhance the accuracy and flexibility of phased array antenna testing workflows.
