The Agilent CSA Spectrum Analyzer
A general purpose spectrum analyzer is the engineer’s
most flexible test tool. The Agilent CSA spectrum analyzer
extends that flexibility with its performance, ease-of-use,
and unprecedented reliability.
Performance and quality you expect at a price you can afford
The Agilent CSA spectrum analyzer brings a level of performance not
seen previously in a compact spectrum analyzer. The highest dynamic
range in its price class is achieved with unmatched distortion
performance, substantial noise performance, and standard 10 Hz
resolution bandwidth. The instrument also offers overall amplitude
accuracy of ±0.5 dB. Now you get all of this capability and more, with
excellent reliability and low service and support costs.
Light weight and portable

Ease-of-use means
greater efficiency
The user interface is designed
to give expert users access to all
of the power of the Agilent CSA.
Logically grouped hard keys, soft
keys, and menus allow intuitive
control of parameters like input
attenuation, bandwidth, and
detector type. Features such as
auto-tune, auto-scale, auto-range,
1 dB step attenuator, built-in
preamp, and onboard help make
the Agilent CSA easy to use even
for non-experts.

Easy to upgrade
Unique among our products, each Agilent CSA spectrum analyzer comes with
options installed, ready to be activated. This allows for easy upgrades, enabling
users to reconfigure the instrument as needs change. Signal source and
preamplifier upgrades may require service center calibration.

Accurate, Rugged, Dependable, and Flexible
The Agilent CSA is optimized for manufacturing
with its combination of high performance, modern
connectivity, and the industry’s best reliability.
The instrument was designed for fast sweep speeds
in narrow resolution bandwidths and fast inchannel measurements, as well as the highest
achievable dynamic range in its price class.
Remote control via 100 Base T LAN and SCPI
reduce the complexity and time to develop
automation software, enhance compatibility
with existing systems, and reduce training time
for manufacturing staff. All of these attributes
are designed to reduce cost-of-test, while the
excellent reliability assures the lowest overall
cost of ownership.
Now you can afford the excellence of an
Agilent spectrum analyzer at each engineer’s
bench!
You get true Agilent performance with TOI of
+18 dBm, 10 Hz minimum RBW (1 Hz minimum
VBW) with 10% adjustability, and 1 dB step
attenuator. The large, bright, 21 cm, 1024 x 768
pixel, XGA display (best-in-class), convenient
form factor, and straightforward portability of
data with a USB memory device make the Agilent
CSA spectrum analyzer easy to use. Features like
auto-tune and auto-scale ensure that newer users
can quickly make use of this extensive performance
and capability.

The Agilent CSA’s field-ready features make it
an ideal choice for installation and maintenance
of today’s complex communication systems.
Weighing just 7.5 k (16.5 lbs) with rugged bumpers,
and a comfortable, adjustable bail handle, the
Agilent CSA spectrum analyzer is able to deliver
powerful measurement capability where and
when you need it. This analyzer has more than
two hours of battery life and a bright, highresolution display, perfect for use in the field.
This instrument combines the functionality
of a general-purpose spectrum analyzer, network analyzer, and power meter into a simple,
easy-to-use package. The built-in VSWR bridge,
optional internal signal source, and stimulus/
response measurement suite confirm the Agilent
CSA spectrum analyzer as the best installation and
maintenance solution in its price class.
The Agilent CSA brings the power of spectrum
analysis to the teaching lab, enabling professors
to easily communicate signal theory to their
students.
Easy transformation between time and
frequency domains simplifies the understanding of digital modulation formats. Built-in help
and auto-setup features bring full spectrum
analysis capability into the hands of aspiring
experts. With the shallow form factor conserving
valuable lab bench space, exceptional performance, and affordable price, the Agilent CSA spectrum
analyzer is a sensible addition to undergraduate and
technical teaching lab stations.
5
Measurements and Features
Communication channel measurements
The Agilent CSA spectrum analyzer includes a number
of communication system channel measurements,
allowing users to accurately assess the performance
of common wireless telephony and other channelbased communication systems and components. Using
preset format-based or custom parameters, the operator can easily determine distortion levels and channel
power using the adjacent channel power function.
Similarly, the occupied bandwidth function quickly
determines power and bandwidth of signals with
complex modulation.
New general purpose features
The Agilent CSA offers a wide range of innovative
features designed to assist non-expert users to
easily set up and make valid measurements. The
one button auto-tune function centers the largest
signal on screen and reduces the frequency span,
allowing the user to quickly zoom in. Auto-scale
sets the reference level and amplitude scale for best
signal viewing.
Auto-range performs
a full-band background sweep,
optimizing input
attenuation and
preamplifier settings,
ensuring that
off-screen signals are
not compressing the
RF stage, assuring
accurate measurement results.
6
Return loss, cable fault, and insertion loss
capabilities
The Agilent CSA’s built-in signal source and
VSWR bridge enable a powerful range of scalar measurements not commonly found in general purpose
spectrum analyzers. With the stimulus/response
measurement suite, the Agilent CSA spectrum analyzer can characterize active and passive single and
dual-port devices such as cables, filters, amplifiers,
multiplexers, antennas, and switches. Measurements
included are 1 and 2 port insertion loss, return loss,
and distance-to-fault. The combination of robust
capabilities and spectrum analysis tools can greatly
simplify and accelerate installation and maintenance of complex components and systems.
Use the spectrogram to analyze the stability of a
signal over time, or to detect and identify signals
interfering with the system of interest.
The spectrogram view is essentially a time capture
of spectral activity that can be optimized to focus
on an area of interest, detailing differences in the
frequency and amplitude of spectral components as
a function of time. A common use for spectrograms
is in the identification and eradication of unwanted interference in communications systems. Spectrograms can also monitor the stability of a circuit or
system over time, temperature, vibration, etc.
7
The Agilent CSA’s optional modulation
measurement suite provides functional and
parametric analysis of AM and FM.
Whether you’re making modulation depth or
frequency deviation measurements for AM or FM
devices, the Agilent CSA spectrum analyzer gives
you the full range of metrics you need. The detailed
measurement information – including deviation,
modulation rate, distortion, SINAD, and carrier
power – ensures a full understanding of the modulation characteristics. Both time domain and
frequency domain views of the data allow you to
analyze the signal quickly from different perspectives.
The tune-and-listen option capability lets you hear
the signal and classify it based on its audio qualities.
Analyze pulsed signals
The CSA clearly and easily displays pulsed signals
in the frequency domain. You can measure the
amplitude difference between a CW signal and a
pulsed signal. The example to the right shows the
Sinx/x of a pulsed signal along with the associated
CW signal.
