VNAs deliver highly accurate, precise advanced measurements
of complex RF signals, such as time-domain analysis, noise figure measurements,
and mixer measurements. High-performance requires precise calibration
techniques, high-quality components, and sophisticated signal processing
algorithms.
Additionally, VNAs cover a wide frequency range, even to millimeter-wave
or sub-terahertz bands. Designing circuits and components that operate at these
frequencies requires specialized materials and manufacturing processes, contributing to higher costs.
So, the complex design, specialized precision components, and technologies needed for modern vector network analysis contribute to the
instrument’s price.
