Chapter 2 — Pulse Analyzer (Option 421)
2-1 Introduction
This chapter gives a brief overview of the Anritsu Field Master Series pulse analyzer and is intended to assist
you in setting up a pulse measurement. This chapter describes pulse references for making pulse
measurements, including selecting the analyzer and setting up frequency, bandwidth, amplitude, sweep, limit
and markers.
2-2 Selecting the Analyzer
The instrument analyzers are selected from the 9-dot icon or the current measurement icon. To select an
analyzer, press the 9-dot icon in the title bar or the current measurement icon to display the available
analyzers, illustrated in Figure 2-1. Simply touch the desired icon to load the new analyzer. The analyzers
available for selection depend on the options that are installed and activated on your instrument. Some
measurements and views are accessed via other measurement setup menus.
