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 2 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.

Test Connector Panel

The connectors and indicators located on the test panel are listed and described below.

12.5-15VDC12.5 to 15 Vdc @ 1100 mA input to power the unit or for battery charging.

(1100 mA)

WARNING

When using the AC-DC Adapter, always use a three-wire power cable connected to a three-wire power line outlet. If power is supplied without grounding the equip- ment in this manner, there is a risk of receiving a severe or fatal electric shock.

Battery	Illuminates when the battery is being charged. The indicator automatically shuts
Charging	off when the battery is fully charged.
External	Illuminates when the Site Master is being powered by the external charging unit.
Power
Serial	RS232 DB9 interface to a COM port on a personal computer (for use with the
Interface	Anritsu Software Tools program) or to a supported printer.
RF Out	RF output, 50 impedance, for reflection measurements.
RF In	RF input 50 impedance for transmission loss or gain measurement.
