Chapter 3
Functions and Operations
Introduction
This chapter provides a brief overview of the Site Master functions and operations, provid-
ing the user with a starting point for making basic measurements. For more detailed infor-
mation, refer to Chapter 4, Measurements and Chapter 5, Software Tools.
The Site Master is designed specifically for field environments and applications requiring
mobility. As such, it is a lightweight, handheld, battery operated unit which can be easily
carried to any location, and is capable of up to 2.5 hours of continuous operation from a
fully charged battery. Built-in energy conservation features allow battery life to be extended
over an eight-hour workday. The Site Master can also be powered by a 12.5 Vdc external
source. The external source can be either the Anritsu AC-DC Adapter (P/N 40-115) or 12.5
Vdc Automotive Cigarette Lighter Adapter (P/N 806-62). Both items are standard accesso-
ries.
Front Panel Overview
The Site Master menu-driven user interface is easy to use and requires little training. Mode,
Frequency, Amplitude and Sweep function keys are located just below the display and are
easily configured for optimum measurements. Selection of one of these keys brings up a
function-specific menu on the right hand side of the display. The softkeys adjacent to the
display provide access to the various menu items (See Figure 3-1).
