Series MS46122A refers to low-cost vector network analyzers (VNA, VNA) of the ShockLine economy line of the Japanese company Anritsu. This is a complete yet very affordable 2-port vector analyzer. Depending on the modification, the upper operating range is 8, 20 or 43.5 GHz. The MS46122A analyzer can measure all 4 S-parameters (reflection on port 1, forward transfer characteristic, reverse transfer characteristic, and reflection on port 2). In addition, measurements in the time domain are possible with option MS46122A-002.
The Anritsu MS46122A vector analyzer is based on the patented ShockLine VNA-on-chip technology, in which all the main elements of the analyzer are placed in one micromodule, which significantly simplifies and makes the internal structure of the device more compact, which in turn significantly reduces the cost and increases the accuracy of measurements. , especially at high frequencies.
The combination of low cost and good performance makes the ShockLine vector analyzers an excellent choice for measuring passive devices up to 43.5 GHz. The Anritsu MS46122A vector network analyzer is controlled by a personal computer via USB. The software is the same for all analyzers of the ShockLine family. It provides ease and convenience of control of the analyzer, at the same time it has a wide range of professional features.

The most cost-effective complete 2-port vector analyzer
In addition, Anritsu produces a more expensive series of vector analyzers: Anritsu MS46322A. The measuring path and characteristics of the MS46322A series are completely identical to the MS46122A series, but the MS46322A contains a built-in computer. Because of this, the MS46322A is slightly larger, heavier and $5000 more expensive, but all processing is done inside the analyzer and you only need to connect an external monitor, mouse and keyboard to it.

Anritsu MS46122A Economy Vector Network Analyzer Video Review
This video review introduces Anritsu's MS46122A Compact Vector Network Analyzer series. These are full-fledged and at the same time very affordable 2-port vector analyzers of laboratory level. After watching this video, you will get acquainted with their capabilities and see examples of real measurements of the characteristics of the attenuator (30 dB, 18 GHz).
The Anritsu MS46122A is a compact 2-port vector network analyzer that connects to a computer via USB. The analyzer is controlled using software that is installed on a computer with a 64-bit Windows 7 or 8 operating system. At the same time, the measurement results are displayed on the computer screen in real time. The use of a computer as a control, processing and display device made it possible to significantly reduce the cost of the analyzer, as well as increase work efficiency due to quick and convenient work with measurement results.
The Anritsu MS46122A vector network analyzer includes a built-in test signal source, switching circuits, and a built-in meter. The MS46122A analyzer is designed for entry-level and mid-level applications that arise in the design and manufacture of microwave devices up to 43.5 GHz. In addition, a detailed programmer's guide, which can be downloaded on this page in the section Documentation, allows you to remotely control the MS46122A analyzer, as well as include it in automated measuring systems. Also, these analyzers can be used in automated systems using IVI-C driver components in the most popular application development environments such as LabVIEW, LabWindows, MATLAB, C# and .NET.
The MS46122A ShockLine Vector Network Analyzers provide best-in-class performance with best speed, stability, dynamic range, and low noise. The minimum test time and increased bandwidth make these analyzers optimal for testing any passive devices: cables, connectors, filters, attenuators, antennas, etc.
High Measurement Accuracy of Anritsu MS46122A 2-Port Vector Network Analyzer
The Anritsu MS46122A Vector Network Analyzer (VNA) contains high-precision measurement circuits that are calibrated can be done manually (using discrete components) or automatically (using a special external calibration module). Uncertainties (errors) of measurements of the main parameters after manual calibration are shown in the four figures below.
Design 2-port vector network analyzer Anritsu MS46122A
Structurally, the Anritsu MS46122A network analyzer is designed as a compact device without a display and control buttons. The symmetrical design provides flexibility and convenience for rack-mounting, as the instrument can be mounted front- or rear-mounted. With a low height of just 1U, the MS46122A ShockLine Vector Network Analyzers save valuable rack space, making them ideal for testing in confined spaces.
The Anritsu MS46122A vector network analyzer is connected to a computer via a USB interface. Modification of the MS46122A-010 analyzer, which operates up to 8 GHz, contains two N(f) connectors for connecting to the measurement object. Analyzer modifications MS46122A-020 (up to 20 GHz) and MS46122A-040 (up to 43.5 GHz - shown in the figure below) contain two reinforced K(m) connectors for connecting to the measurement object.
