develop and produce, and that you
must evaluate and test?
That is what an Agilent N9320A
spectrum analyzer brings you,
whether you are identifying and
eliminating sources of unwanted
interference or checking the
stability of circuit components or
You'll want to make just sufficient
performance checks to develop

Simplify common power
measurement tasks
Power measurements made easy
using the measurement suite
Single-key auto-tuning allows you
quickly to home in on the highestlevel signal across the bandwidth.
Centering this signal on the screen,
the analyzer simultaneously reduces
the frequency span. Auto-scaling and
ranging enhance accurate, speedy
One of the most fundamental
measurements performed by
spectrum analyzers is the frequencydomain measurement of RF power.
However, detailed analysis of a signal
often requires standards-defined
spectral mask tests or more complex
power/bandwidth measurement
When you find yourself having
repeatedly to make the same type of
complex measurement or
measurement sequence, it is useful
to know some shortcuts. That's what
we have provided for you in your
N9320A spectrum analyzer.
Channel power
Accuracy and speed of the integrated
channel power and computed power
spectral density from the RMS
averaging detector.
Adjacent channel power (ACP)
Fast, accurate simultaneous filtered
RMS power measurement in up to six
offset power bands. Ideal for mobile
telephony applications.
You will find that the in-built suite of
power measurements shortens
routine test set up time by simplifying
keypad/menu selection.
Of course, you retain the flexibility to
tailor each measurement task to your
specific needs when necessary. And
you'll find it easy to distinguish
between signals having large level
differences since the analyzer has
one of the widest dynamic ranges for
a tester in its price range.
Selecting these directly from the softkey menu also helps ensure accuracy
of test set up.
Simple PC connection via USB
The N9320A spectrum analyzer
continues the Agilent tradition that
today's testers should be easy to set
up, and simple to use.
Occupied bandwidth
Specifying the power percentage
places markers at the upper and
lower frequencies of the appropriate
bandwidth representing this power.
Those familiar with other Agilent
spectrum analyzers will find similar,
user interfaces here in this low-cost
tester, allowing for simpler set up and
making measurements.
Built to perform
you to compete
It is easy and convenient to operate
your spectrum analyzer from a PC
connected to the USB ports.
USB ports on front and back panels
make interconnection to a PC
particularly straightforward.
Each analyzer comes with PC-based
virtual panel software utilities and
drivers. These replicate all controls
and setup parameters of the large,
full-color display on the analyzer's
front panel. Analyzer control is then
through the PC's virtual panel display
priced for
Furthermore, this software provides
useful and straightforward data
analysis productivity tools for you,
allowing uncomplicated data logging
and archiving of important test
results, including graphics.
and maintenance
Detecting low signal levels whilst
simultaneously resolving closelyspaced frequencies is a
fundamental requirement for RF
testing. Employing one of the
best combinations of sensitivity
and narrow resolution bandwidth
(RBW) ensures that an N9320A
spectrum analyzer will readily
handle these tasks.
When it comes to receiving the best return
from your R&D equipment budget, turn to
Agilent's new generation of low-cost
sources and analyzers.
Your N9320A has all-round application
in field installation and maintenance.
A strong, handy carrying case and front and
rear transit bumpers protect your analyzer
when in transit.
Limited on your R&D budget?
An effective, professional field
installation and maintenance tool
You'll find an N9320A spectrum
analyzer equally versatile for lowbudget R&D applications, too. It is
equally suitable for new RF design
verification or when initiating a lowcost project for product
enhancements and extensions.
Most installation and maintenance
tasks demand fast, cost effective test
solutions. Being small and
lightweight, an N9320A spectrum
analyzer is as functional and
indispensable in low-cost bench
repair applications as it is for field
Bench repair
So whether it is to aid
straightforward device tuning on the
bench, or carrying out more complex
repair or regular maintenance on
base stations in the field, the N9320A
spectrum analyzer will find a place in
any RF technician's toolkit.
Wherever you deploy your engineering and
hardware resources, everyone will find

Multi – language screens and manuals
enhance usability as design and
manufacturing services move around the
world:shortly, other languages will follow.
The N9320A can become portable with
handle and bumper. It makes the N9320A
an ideal choice for installation and maintenance.
Learning how to use test
instrumentation, and understanding
how RF signal interact are
fundamentals for electronics studies.
Spectrum analysis is one test
essential to good circuit design. It
brings signal interactions to light for
students and helps explain signal
mixing processes.
