MS20xxA VNA Master UG 10580-00166 Rev. C 3-1
Chapter 3 — Vector Network
Analyzer
3-1 Introduction
This chapter provides an overview of the vector network analyzer capabilities of the Anritsu
VNA Master, which is available in both MS202xA and MS203xA models. The intent of this
chapter is to provide the user with a starting point for making basic measurements.
The VNA Master offers a wide range of display options for 1-port and 1-path 2-port vector
corrected measurements. The Application Options menu contains the
Meas Menu soft key that
allows the selection of Field or VNA measurement menus. Although the Field and VNA
measurement menus use different names for the measurements, the actual measurements
are the same. Cable Loss measurements are available only in the Field menu.
3-2 VNA First Time Use
Before conducting a measurement in vector network analyzer mode, select a measurement,
specify the frequency range, and perform a calibration. The following paragraphs further
explain these steps.
Selecting the Measurement
The Measurement Menu (refer to “Measurement Menus (Field and VNA)” on page 3-40) can
be accessed by pressing the
Measurement function hard key below the display or by pressing
the
Shift key followed by the Measure (4) key. All VNA Master measurements can be found in
the Measurement Menu.
The Measurement Menu can changed between two different settings (Field or VNA). For
users already familiar with the Anritsu Site Master measurement nomenclature, the Field
setting will likely be more comfortable. The VNA setting is designed to more closely resemble
the menus of a bench top VNA, and allows access to more advanced features of the VNA
Master.
Change between the Field Menu and the VNA Menu (for S11 Log Magnitude and S21 Log
Magnitude measurements) by pressing the
Shift key followed by the System (8) key, and
selecting
Applications Options. Press the Meas Menu soft key to toggle between Field and VNA.
VNA Menu measurements included for S11 Reflection are:
• Log Magnitude
•VSWR
•Phase
• Smith Chart
• Log Magnitude Fault Location
• VSWR Fault Location
•Group Delay S11
