The new RF Vector Network Analyzer (VNA) gives designers, production engineers, and educators affordable access to many capabilities of conventional bench-top network analyzers.  

The VNA covers 200 kHz to 120 MHz. It’s used to test low-power amplifiers, determine characteristics of coax cables, measure and adjust filters, check antenna impedance versus frequency, measure antenna SWR, and even measure the length of transmission lines using the time domain reflectometer (TDR) feature.

The VNA measures the forward and reverse gain and phase response of a circuit. It also measures I/O reflection (complex impedance), provides S parameters, and measures one- (input and ground) and two-port networks (input with ground and output with ground). The VNA also functions as a general-purpose signal generator. 

To use the VNA, load the software on a Windows-based PC and connect to a USB 1.1-compatible port. A Linux version is currently under development.

The VNA costs $655.
