Chapter 2 — Instrument Overview
2-1 Introduction
This chapter provides a brief overview of the Anritsu LMR Master. The intent of this chapter
is to acquaint you with the instrument. For detailed measurement information, refer to a
specific measurement guide listed in Appendix A, “Measurement Guides”.
2-2 Turning On the LMR Master
The Anritsu LMR Master is capable of approximately three hours of continuous operation
from a fully charged, field-replaceable battery (refer to Section 1-4 “Battery Replacement”
on page 1-6).
The LMR Master can also be operated from an external power source (which also
simultaneously charges the battery). This can be achieved with either the Anritsu AC-DC
Adapter or the Automotive Cigarette Lighter Adapter. Both items are included with the
LMR Master.
To turn on the LMR Master, press the green On/Off button on the front panel (Figure 2-1).
The LMR Master takes approximately sixty seconds to complete power warm-up and to load
the application software. At the completion of this process, the instrument is ready for use.
2-3 Front Panel Overview
The LMR Master menu-driven interface is easy to use and requires little training. The
LMR Master uses a touch screen and keypad for data input. The five bottom menu keys and
eight submenu keys on the right side are touch screen keys. The menu and submenu keys
vary depending upon the selected mode of operation. Refer to “Mode Selector Menu”
on page 2-16.
Numeric keys 1 through 9 are dual purpose, depending upon the current mode of operation.
The dual-purpose keys are labeled with a number on the key itself, and the alternate function
is printed in blue above each of the keys. Use the blue Shift key to access the functions that
are printed on the panel. The Escape key, used for aborting data entry, is the oval button
located above numeric key 9. The rotary knob, the four arrow keys, and the keypad can be
used to change the value of an active parameter.
The Menu key provides graphical icons of all of the installed measurement modes and user
defined shortcuts (refer to “Menu Key” on page 2-3). The locations of the keys are shown in
Figure 2-1.
Caution
When using the Automotive Cigarette Lighter Adapter, always verify that the
supply is rated for a minimum of 60 Watts at 12 VDC, and that the socket is clear
of any dirt or debris. If the adapter plug becomes hot to the touch during operation,
discontinue use immediately.
