Vector Network Analyzer (VNA)

A Vector Network Analyzer (VNA) is a specialized instrument used to measure how radio frequency signals behave when transmitted through electronic components or systems. It sends known signals into a device and analyzes the reflected and transmitted signals to determine parameters like impedance, loss, and signal quality. This helps engineers evaluate and optimize components such as antennas, cables, and filters for better performance. VNAs provide detailed, phase- and amplitude-sensitive data, making them essential for designing and troubleshooting high-frequency electronic systems in communications and aerospace.
