Introduction

This manual provides maintenance instructions for the Anritsu LMR Master S412E.
The information includes:
• Chapter 1, "General Information"
• Chapter 2, "Vector Network Analyzer Verification"
• Chapter 3, "Spectrum Analyzer Verification"
• Chapter 4, "CW Signal Generator Verification"
• Chapter 5, "Option Verification"
• Chapter 6, "Battery Information and Replacement"
• Chapter 7, "Assembly Replacement"
• Chapter 8, "Troubleshooting"
• Appendix A, "Test Records"
Anritsu recommends that you make a copy of the blank test records to document the
measurements each time a Performance Verification is performed. Continuing to document this
Note
process each time it is performed provides a detailed history of instrument performance, which
allows you to observe trends.
Throughout this manual, LMR Master and S412E are used interchangeably to refer to the instrument.
Familiarity with the basic operation of the front panel keys (for example, how to change measurement
mode, preset the unit, or the meaning of submenu key or main menu key) is assumed. Refer to the
LMR Master S412E User Guide (Anritsu part number 10580-00318) for basic operation information.

Product Description

The S412E LMR Master is a portable handheld vector network analyzer (VNA), spectrum analyzer (SPA), and
signal generator (SG). The VNA features precise performance and essential RF capabilities. It is designed to
conduct accurate vector-corrected 1-port magnitude, phase, and fault location measurements and 2-port
magnitude, phase, group delay measurements from 500 kHz to 1.6 GHz for the base unit with an option to
extend the upper frequency to 6 GHz. The SPA is capable of providing quick and accurate measurement results
for monitoring, measuring, and analyzing signal environments. The SPA offers broad spectrum analysis with
frequency coverage to 1.6 GHz for the base unit with the option to extend the upper frequency to 6 GHz.
The LMR Master offers impressive dynamic range and excellent phase noise performance. Standard
measurements include field strength, occupied bandwidth (OBW), channel power, adjacent channel power
ratio (ACPR), and carrier to interference (C/I) ratio. The SG allows the user to generate modulated signals from
500 kHz to 1.6 GHz. The amplitude of the signals range from –130 dBm to 0 dBm.
Frequency Ranges
• VNA, 500 kHz to 1.6 GHz (6 GHz with Option 16)
• SPA, 9 kHz to 1.6 GHz (6 GHz with Option 6)
• SG, 500 kHz to 1.6 GHz
