Introduction

This chapter includes Vector Network Analyzer (VNA) measurement capabilities and
instrument architecture information. It also describes calculating and displaying
S-parameters, and describes using markers to provide additional measurement information.

VNA is Vector Network Analyzer or Vector Network Analysis. The VNA Master and the
LMR Master are Vector Network Analyzers that measure the magnitude and phase
characteristics of 1-port or 2-port networks, including cables, antennas, filters, isolators,
attenuators, and amplifiers. The Vector Network Analyzer compares the signal that leaves
the analyzer port (the reference signal) with either the signal that is transmitted through the
test device (the transmitted signal) or the signal that is reflected from the input or the output
of the test device (the reflected signal).
Compared to a Scalar Network Analyzer (SNA), a VNA has the added capability for
measuring phase characteristics. While phase measurements are important in themselves,
the availability of this phase information unlocks many new features for complex
measurements. These features include Smith Charts, Time Domain, and Group Delay. Phase
information also allows greater accuracy through vector error correction of the measured
signal.
A VNA can have 1-port only, in which case it measures only reflection signals. A VNA can
have 2-ports, in which case it can measure both reflection and transmission. A 2-port VNA
can also have two different capabilities: 1-path 2-port, or full-reversing. The 1-path 2-port
design allows reflection measurements only at one of the two ports and allows transmission
measurements only in one direction.
The MS20xxB VNA Master and the S412E LMR Master are two-port, 1-path VNA
instruments that allow S
The MS20xxC VNA Master is a full-reversing VNA that allows reflection measurements from
both ports and allows transmission measurements in both directions (S
measurements with a single connection).
