Creating a Database
A single trace or a block of traces can be transferred from the instrument to the PC. A sepa-
rate database can be created for each cellular site. The site name can be used as the database
name.
Step1.
Select the
File
menu and select the
Database
.
Step2.
Open an existing database or create a new database with a descriptive filename
that represents the site name.
Once the database has been created, files can be saved and site information can be added,
such as Plot Description, Date/Time, Operator, record/trace number and session description
(transmitter type, etc.)
Individual plots will be labeled with the Database Site Name. Each record has its own plot
description and measurement type.
Printing Formats
One to multiple plots per page can be set up under the print format in Handheld Software
Tools. Orientation of how the plots are printed on the page can be changed from vertical to
horizontal.
Entering Antenna Factors in Handheld Software Tools
NOTE: The Antenna Factor parameter is only applicable to Anritsu Hand Held
Spectrum Analyzers.
The Antenna Factor (AF) is a fundamental parameter of an antenna used in field measure-
ments. AF is used in the calculation of field strength during radiated emissions measure-
ments, and relates the value of the incident electric or electromagnetic field to the voltage at
the output of the antenna. For an electric field antenna, this is expressed as:
AF E
Vl
=
Where AF = Antenna Factor, m
-1
E = Electric field in Volts per meter
V
l
= Voltage at the antenna terminals in Volts
It also can be shown that in a 50 ohm system:
AF
Gr
=
9 73
.
l
Where G
r
= the gain of the receiving antenna in dB
l
= wave length in meters
