Field Strength Measurements
Electromagnetic field strength measurements are frequently required for
transmitter and antenna coverage testing in the field.
The N9340B includes field strength measurements as a standard function.
Calibrated field strength measurements are easy to make once antenna factors
have been loaded into the analyzer via the antenna template provided by the
N9340 PC software.
The N9340B provides you with quick and convenient field strength measure-
ments and analysis. Either field strength (in dBmV/m, dBmV/m, or V/m) or
power flux density (in dBm/m or W/m) can be displayed. Use the amplitude
offset function to correct gain or loss. You can also set limit lines for pass/fail
testing.
In the following demo, an Omni antenna with a frequency range from 890 MHz to
960 MHz is needed.
1. Edit the antenna factor file and load it into the N9340B
via USB cable.
Instruction
Key strokes
Connect the N9340B to a PC using a USB
cable.
Run the Keysight N9340 PC software on
the PC.
Click the N9340 PC software shortcut
key on the PC screen.
Open a new antenna file.
{File}, {New} select the antenna file.
Edit the antenna file.
{Insert}, fill out the antenna parameters
in the antenna point dialog box, such
as frequency, antenna factor and antenna
gain.
Repeat the previous step until all points have
been entered.
Save the file.
Click the save shortcut key on the toolbar.
{File}, {Save}, choose the directory, enter
the file name and save it.
Open the File Manager menu.
Click the shortcut key for the File
Manager.
Highlight the corresponding USB
address of the N9340B in the instrument
list dialog box.
Click {ENTER}, then the File Manager
dialog box will appear.
Transfer the antenna file from the PC to
the N9340B.
Click the Send button.
Select the file you want to transfer in the
open dialog box.
Click Open and the file will be transferred
from the PC to the N9340B.
