Handheld Spectrum Analyzer (HSA)
N9340B
IBOC measurements
(Option IBC)
Option IBC has built-in FCC and NRSC
(National Radio Systems Committee) spectral
emission masks for quick compliance
measurements with visual and audible
pass/fail indicators.
N9340B IBC also supports a one-button
auto-tune function that greatly simplifies the
otherwise complex user setup required to
capture and measure IBOC signals of interest.
The auto-tune function will automatically set
the frequency span, RBW, Average and
Detector types, etc. It only takes seconds for
the auto-tune function to display the correct
measurement results.
The included Channel list feature enables users
to easily create and recall setup and
measurement parameters for single or multiple
broadcast frequencies and channels. The user
no longer needs to spend time remembering
numerous channel setups but can simply load
the desired channel from the list to start a
measurement. The Channel list can be
loaded, copied and deleted.

Users may choose to make the xDSL
measurement in either spectrum analysis
or spectrogram mode. Using xDSL
measurement in spectrogram mode is ideal
for capturing intermittent interference on
xDSL lines. When used with option INM,
the DSL measurement application can
measure and record DSL performance data
to a USB flash drive or PC over hours or even
days.
An xDSL probe from Vierling is required to
connect the N9340B analyzer to xDSL
networks for measurements in the field.
N9340B is the industry’s first handheld spectrum
analyzer with a dedicated IBOC measurement
mode. The option IBC is not available as an
upgrade and must be ordered at the time of
instrument purchase.

ADSL measurement with N9340B XDM
The option XDM is not available as an
upgrade and must be ordered at the time of
instrument purchase. The XDM option can
also be used for other applications which
require improved DANL and phase noise at
frequencies from 9 kHz to 12 MHz.
Option IBC equips the N9340B with in-band
on-channel (IBOC) measurement capability
through a dedicated measurement personality
and selected hardware improvements. IBOC
technology is a method of transmitting digital
and analog radio broadcast signals (AM and
FM) simultaneously on the same frequency.
This HD Radio™ version of hybrid digital/
analog technology is the only one approved by
the FCC for U.S. radio broadcast stations.
The IBC option adds enhanced SSB phase noise
for IBOC AM measurements and a noise
cancellation process for improved IBOC FM
measurement margins. IBOC-AM covers 530
kHz to 1.7 MHz and IBOC-FM covers the 87.5
MHz to 108 MHz frequencies.

The occupied bandwidth measured in dBc.
The occupied bandwidth measured in
percentage.
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.
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.
Occupied bandwidth (OBW)
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.
