Regardless of whether you are handling
military communications, a Wireless
Service Provider (WSP), or involved
with spectrum management you need
to avoid impaired communication.
The N9340B provides you with a reliable,
accurate and detailed picture of your
communication spectrum.
When you test, you need fast data
capture to help locate and identify
elusive, transient interference signals.
That’s why every N9340B spectrum
analyzer has a truly fast sweep time.
It requires less time to measure across
the spectrum, to obtain more reliable
test results and to help you achieve
more for the same investment of time
and money.

Spurious signals and noise are of great
concern to all network users. A superior
combination of low displayed average
noise level (DANL) and single sideband
(SSB) phase noise coupled with a
narrow resolution bandwidth (RBW)
means your signal measurements are
more reliable and you will have more
confidence in your test results. The
N9340B’s low DANL and SSB phase
noise helps you detect very low-level
signals (spurs or noise) which are close
to the carrier. You will avoid missing
these difficult-to-identify signals, which
would otherwise lead to an insufficient
or even incorrect understanding of the
spectrum.
The N9340B’s RBW is the narrowest in its
class. The narrow 30 Hz bandwidth of the
analyzer ensures that it is even easier
to identify, resolve, and measure two
signals that are close together.
Additionally, with a resolution filter
shape-factor of less than 5, the N9340B
has the ability to resolve closely spaced
signals with unequal amplitudes.
Moreover, the narrow RBW means that
the spectrum analyzer introduces minimal
noise itself, helping to further reduce
DANL and improve sensitivity.
N9340B Superior Performance Ensures the Field Test Confidence
Superior sensitivity: lowest DANL in-the-class
Fastest sweep time
Narrowest resolution available
Superior sensitivity
With more wireless devices on the market
requiring greater bandwidth usage, the
ability to discriminate between different
signals becomes more challenging. It’s
under such demanding conditions that the
superior performance of an N9340B
analyzer proves its worth. The N9340B
has one of the best sensitivity and
selectivity specifications. The DANL is
–124 dBm, or –144 dBm with the
optional preamplifier (30 Hz RBW, 10
MHz < fc < 1.5 GHz).
–
The optional
preamplifier adds 20 dB gain for
improved analyzer sensitivity.
Speed at your fingertips
The RF spectrum is a finite resource,
therefore its usage requires management.
Most regulatory authorities responsible
for administering frequency allocation
require service suppliers and network
operators to perform routine
monitoring of signal power and
transmission frequency stability..

N9340B
Spectrum emission mask
The new N9340B adds Spectrum Emission
Mask (SEM) as a standard feature. SEM is
a mask for out-of-channel emissions
measurement. The SEM is defined relative
to in-channel power.
The user can set the parameters of the main
channel, out-of-channel frequency bands,
and the limit lines. Included is Pass/Fail
testing for the overall spectrum emission
mask and each individual out-of-channel
frequency range. The N9340B will trigger
the failure indicator once any measurement
result violates the mask.
Also displayed are the main channel power
and the power level metrics relative to
in-channel power for each out-of-channel
frequency range. The user can save the
spectrum scan, the mask, the data or
screenshot for later analysis and reporting.
Spectrogram
Now you can take advantage of the
spectrogram display to view the behavior of
varying signal parameters over time. The
N9340B includes spectrogram as a standard
feature. The scrolling three-dimensional display
is noted for its ability to track the frequency and
power behavior over the time, particularly
intermittent signals. The user can use
spectrogram to analyze the stability of a signal
over the time, or to identify intermittent
interference signals in communications systems.
There are two markers for the user to identify
power versus frequency and time. Also the time
interval between two consecutive colored rows
can be adjusted. When a marker is put on the
spectrogram, the N9340B can display the trace
for the time of the selected marker.
The spectrogram data and screenshots can be
saved and recalled for later analysis or reporting.
N9340B is now equipped with powerful
features to address field applications
using a handheld spectrum analyzer.
An important application of spectrum
analysis is identifying interfering signals.
These often arise from illegal transmissions,
and may cause impairment of services
for authorized users, often resulting in
financial loss. These interfering signals
could possibly restrict critical
communications of civil aviation and
emergency services, which could
jeopardize public safety.

Field strength measurement
New
Electric field strength measurements are frequently
required for field testing of transmitter and antenna
coverage. Field strength measurements are now a
standard function in the N9340B. Calibrated field
strength measurements are easy to make once the
antenna factors are loaded into the analyzer via the
provided PC software based antenna template.
Either field strength (in dBµV/ m, dBmV/ m, or V/
m) or power flux density (in dBm/ m or W/ m )
2
2
can be displayed. With the amplitude offset function,
the user can correct gain or loss. And finally together
with the user-definable multi-limit line function, the
N9340B offers the user quick and convenient field
strength measurements and analysis.
The spectrum emission mask shows the main
channel power and the power level vectors
relative to in-channel power for each out-of-channel
frequency range.
The spectrogram gives the three-dimensional
display of power, frequency and time.
The field strength measurement automatically
takes into the account of the antenna factor.
The antenna table is definable by the standard
N9340B PC software.

no external power supplies and with
internal zeroing eliminate the need for
external calibration. Without the need for
additional boxes, the user can easily set up,
calibrate and control the power meter/sensor
via the analyzer’s USB port. The N9340B
can collect, display and save the power
meter results.
The analyzer also provides Pass/Fail
testing with user set upper and lower
limits and a Pass/Fail indicator. Test
results are shown in dBm and W when
making absolute measurements and in
dB and percentage when measurements
are relative. Two display modes are
available: Meter or the Chart mode to log
power measurements over time.

Channel table
New
For the users who prefer to tune the spectrum
analyzer according to channel numbers rather
than center frequency, you will find the new
Channel Table feature easy-to-use. The
Channel Table includes the major wireless
communication standards, such as AMPS,
GSM/EDGE/GPRS, CDMA, CDMA2000 etc.
The Channel Table can also be edited by the
user with the included N9340 PC Software.

downloaded to the analyzer via a PC USB
cable or a USB memory stick.
The channel table offers the ability to tune N9340B
according to channel numbers.
One-button measurement
The Agilent N9340B supports one-button
measurements of occupied bandwidth, channel
power and adjacent channel power ratio.
This virtually eliminates set-up time in the field.
Occupied bandwidth (OBW)
An occupied bandwidth measurement
integrates the power of the displayed
spectrum and puts one pair of vertical lines
at the frequencies between which the
interested signal is contained.
An N9340B spectrum analyzer supports two
ways to measure the occupied bandwidth, in
percentage or in dBc.
The occupied bandwidth measured in
percentage.
Channel power
Use channel power to measure both
power and power spectral density in
a user-specified channel bandwidth.
One pair of vertical lines on the display
indicates the edges of the channel
bandwidth.
It is quick and easy to set center frequency,
integration bandwidth, and channel bandwidth.
Adjacent channel power ratio
(ACPR)
Wireless service providers need to
minimize the interference caused
by power leaking into adjacent
transmit channels. Adjacent channel
power ratio measurements help to
check for signal leakage and the
identification and control of
sources of interference.
The channel table is editable by N9340B PC software.
Safety at high input levels
The N9340B can be used for many high
power applications. However, should the
power level exceed33 dBm, the input
protection switch activates to protect the
instrument from damage.
The maximum safe input level is > +33
dBm for 3 minutes at most < 50 VDC.
The occupied bandwidth measured
in dBc.
Center frequency, main channel bandwidth,
adjacent channel bandwidth, and channel
space can easily be set.
