The new
PSG vector
signal generator
can help you
simulate real-world
environments
Custom pulse waveform created with MATLAB® and generated with
the E8267C PSG
The new E8267C PSG vector signal
generator, a member of Agilent’s
next-generation of performance
signal generators, opens new doors
in the testing and characterization
of microwave components and
systems in a single integrated
instrument.
Many systems that operate at microwave
frequencies need modulation bandwidths
ranging from tens to hundreds of megahertz, whether they are pulsed radar sets
or broadband wireless communication
systems employing vector modulation
to transfer high data rate signals. The
E8267C has features that enable the
generation of these signals and include:
• Internal I/Q modulation capability
which enables users to input external
baseband analog I/Q signals up to
160 MHz RF modulation bandwidth
through BNC ports on the front panel.
• Optional wideband I/Q inputs with RF
modulation bandwidth of 1 GHz.
Although uncalibrated, these inputs are
useful for many broadband applications.
Typical plots of frequency response are
provided in the PSG vector data sheet.
• Optional internal baseband generator,
which operates in dual mode, combining
the capabilities of a 32 Msample, deep
memory arbitrary waveform generator
with the sophisticated coding power of
a real-time baseband generator.
• Standard two-tone and multitone
applications are built into the optional
internal baseband generator of the PSG
vector signal generator. Users can
press a few simple soft keys to quickly
generate multitone waveforms, and
define relative tone spacing, relative
tone power and phase relationships.
These capabilities eliminate the issues
associated with combining multiple
continuous wave signal generators,
and significantly reduce test costs.
• Compatibility with industry-standard
software packages – including Agilent’s
Advanced Design System (ADS) software and other industry standard
software packages such as MATLAB
and Excel® – which makes it easy to
generate customized arbitrary waveform
files. Once a waveform file has been
developed, engineers can use Agilent’s
free PSG/ESG Download Assistant PC
software. This software works entirely
in the MATLAB environment. Developers
can use these functions to download
MATLAB I/Q data into the volatile
memory of the signal generator and play
it back with a single command. Also,
customers can use Agilent’s Intuilink, a
free connectivity software, that allows
easy transfer of measurement data and
images from instruments into PC
(Microsoft Word® and Excel) with little
or no programming.

Easy creation
of complex
waveforms for
your application
Do you want to simplify your
radar receiver characterization?
The new E8267C PSG vector signal
generator utilizes I/Q modulation to simulate pulsed signals in a single integrated
instrument. Now, arbitrary waveforms
representing pulsed radar signals can be
defined in the time domain using Agilent’s
Signal Studio for pulse building, Advanced
Design System (ADS), or even MATLAB
software. Using vector modulated arbitrary
waveforms eliminates many of the
synchronization issues associated with
pulsing modulated signals using traditional
analog techniques. Also, the PSG vector
signal generator’s deep playback memory
and waveform sequencing facilitates the
generation of complex pulse test patterns
for radar receiver tests.
Features of the E8267C PSG that are
useful for radar test:
• Arbitrary vector waveform generation
• Flexible waveform sequencing for
complex pattern generation
• Mass storage for archiving pulse
waveforms
• Narrow pulse modulation specified
down to 10 MHz
• Signal Studio software for pulse building used for simplified custom pulse
shaping, pulse compression, and pulse
sequences
Do you need digital signals
for your satellite, point-topoint, LMDS, and MMDS
applications?
From subsystem tests through manufacturing and post-launch verification, there
is a need to ensure that each module or
radio will function properly when it is
integrated into the end-to-end communications system. Traditionally, either “golden
devices” or a combination of test equipment was used to generate the desired
microwave test signals. These types of
solutions are generally un-calibrated and
cost intensive. With the PSG vector signal
generator you are investing in a guaranteed
performance in a single integrated instrument. The PSG E8267C is able to adapt
to your test environment and help you
overcome interoperability challenges
with a broad range of capabilities.
Features of the E8267C PSG for
microwave communication systems:
• Internal baseband generator with
80 MHz of RF bandwidth
• Flexible modulation with simplified
setups for basic formats
• Extended RF modulation bandwidth
to 1 GHz
• Deep waveform playback memory for
playback of long complex signals
• Maximum 50 Msymbol/s for high data
rate applications
Note: For vector modulation above 20 GHz,
combine an Agilent ESG vector signal generator
to provide IF vector signal (or other RF vector
signal generator) with the E8247C or E8257C
equipped with Option H30 or H34 which provides
IF up-conversion to 46 GHz. Please consult your
Agilent sales representative for further
information about this solution.

Cost-effective testing of
microwave components
For component or subsystem testing,
speed and accuracy are critical and it is
imperative to continuously improve test
processes and reduce costs. The PSG
signal generators deliver with high
performance and innovative capabilities
that exceed other microwave signal
generators. To simplify non-linear device
characterization, the PSG vector signal
generator provides application specific
personalities for performing two-tone and
multitone signal generation. The issues
associated with combining multiple signal
generators no longer need to be addressed
and the cost of test is significantly reduced.
High throughput ramp sweep has been
added to perform frequency and power
sweeps for stimulus response applications.
The new PSG operates automatically
with the 8757D scalar network analyzer
providing faster sweeps and more dynamic
range than our previous solutions. The
PSG’s industry standard high output power
provides 10-20 dB more dynamic range
for your scalar measurements. The new
PSG is SCPI code compatible with existing
Agilent microwave sources, and it is
compatible with Agilent’s millimeter wave
source modules that can extend frequency
up to 110 GHz.
Component manufacturers will now be
able to accurately test their products with
the signal environment in which the component will ultimately be used, reducing
costly failures during system verification.
Features of the PSG signal generators for
component characterization:
• Multitone signal generation with a
single instrument
• Industry leading performance for high
output power and enhanced phase
noise
• Convenient sweep modes: analog ramp
sweep, digital step sweep, and list sweep
• 8757 scalar network analyzer compatibility
• Backwards code compatibility with
Agilent 836xxB/L, 837xxB,
E824x/E825xA, and 8340/8341 signal
generators
• Frequency coverage up to 110 GHz using

The Signal Studio software for pulse
building is the first of a collection of PC
applications that is compatible with the
new PSG vector signal generator. Agilent
is introducing this application on the PSG
vector, which allows radar system developers to create optimized pulsed signals
using the I/Q signals from the baseband
generator.
• Easy navigation of the intuitive user
interface
• Creation of a pulse library
• Construction of custom pulse shapes
• Applying intra-pulse modulation
• Building a pattern library
• Application of baseband pre-distortion
• Improve image rejection
• Optimization of RF modulation flatness
• Automation using the COM-based API
When utilizing this Signal Studio software,
the mathematics required to calculate the
I/Q waveform samples will be transparent
to the user. By simply setting a few highlevel pulse parameters like rise time, ramp
profile, intra-pulse modulation — even the
novice user can create complex radar
waveforms. When combined with an
Agilent ESA or PSA spectrum analyzer, the
Pulse Builder software applies pre-distortion to the calculated waveform to
improve image rejection and RF flatness.
Corrections can also be applied to custom
I/Q user data that has been imported to
the software For further information about
