Chapter 2
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 the specific chapters for the measurements being made.
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 1.5 hours of continuous operation from a
field replaceable battery for extended time in the field. Built-in energy conservation fea-
tures allow battery life to be further extended. 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 40-163) or 12.5 Vdc Automotive Cigarette Lighter Adapter (P/N 806-62). Both items
are standard accessories.

12.5 to 15 Vdc @ 3A input to power the unit or for battery charging.
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, or
damaging the equipment.
