In addition, a VNA can also measure the gain or loss between two ports of a circuit, again by magnitude and phase. But where a multimeter measures a resistor at DC (0 Hz), a VNA measures resistance of an RF or microwave circuit at their operating frequency, measuring both the resistance and the phase (they make up a Vector) of the circuit. What does a Vector Network Analyzer do?Ī Vector Network Analyzer (VNA) is much like a multimeter that measures resistance. This page shares some of the frequently asked questions for your information.
As a VNA vendor we get many questions from our customers.
