software combination. The N4010A/
89601A combination adds the
flexible digital demodulation and
analysis capabilities of the 89601A
software to the frequency coverage
and capabilities of the N4010A.
This guide also characterizes the
performance of the N4010A and the
89607A wireless LAN WLAN) test
suite software combination. The
N4010A/ 89607A combination allows
for quick and accurate standards-
based transmitter testing for
IEEE 802.11b/g formats.
Product Overview
N4010A wireless connectivity
test set
The N4010A is a test set designed to
quickly and accurately measure
emerging wireless connectivity
formats in the 2.4 GHz band. The
N4010A offers two bandwidth
selections of 5 and 22 MHz, making
the N4010A an ideal test platform
for Bluetooth™ and WLAN RF
measurements. The N4010A with
Bluetooth Option 101 is an effective
measurement tool for development,
integration, pre-qualification, and
volume manufacturing. Use Option
N4010A-101, with eight different
Bluetooth RF cases, for making
transmitter and receiver measure-
ments as defined in the Bluetooth 1.1
RF test specification. The Bluetooth
test set also includes an internal test
sequencer to shorten test and devel-
opment time. The N4010A with
WLAN Option 102 includes integrat-
ed source and receiver hardware to
verify that 802.11b/g modules and
devices meet their RF design
requirements.
89601A VSA software
The 89601A VSA software provides
flexible tools for making RF and
modulation quality measurements
on digital communication signals.
Analyze a wide variety of standard
and non-standard signal formats
with the 89601A software. Standard
signal presets cover GSM, EDGE,
cdmaOne, cdma2000, W-CDMA,
Bluetooth, 802.11a/b/g, and more.
For emerging standards, the 89601A
software series offers 24 digital
demodulators with variable center
frequency, symbol rate, filter type,
and filter alpha/BT. A user-adjustable
adaptive equalizer is also provided.

Quickly evaluate and troubleshoot
digitally modulated signals with the
modulation analysis tools in the
89601A software. Examine symbol
behavior with trellis/eye diagrams.
Use the constellation and vector
diagrams for an overall indication of
signal behavior and to obtain clues
to the cause of the problem. Take
advantage of the EVM, EVM
spectrum, and EVM time capabilities
for more sensitive examination of
signal errors.
Perform time domain analysis using
the 89601A software RF scope
capability. Evaluate pulse shape
with the main time display, select
specific portions of a burst for
analysis with the time gating
feature, and use statistical tools
such as CCDF and CDF to character-
ize the noise-like behavior of your
modern communication signal.
Simplify the characterization of your
signal with the zero-span spectrum
analysis tools in the 89601A analysis
software. With the wide selection
of spans available in the 89601A
software, match your measurement
span to your signal bandwidth, to
maximize signal-to-noise ratio SNR)
analysis. FFT-based resolution
bandwidths down to less than 1 Hz
provide all the resolution needed for
frequency domain investigations.
A power spectral density PSD)
function is useful for estimating
the level of the noise floor when
calculating SNR. Additionally, a
spectrogram display is provided for
monitoring the wideband behavior
of hopping signals over time.
89607A WLAN test suite software
The 89607A standards-based test
suite provides the convenience of
automatic, one-button test set-up
and execution. It also provides you
with the confidence of knowing your
design is being tested based on
the techniques, parameters, and
specifications set down in the IEEE
802.11a/b/g standards.
The 89607A WLAN test suite
software is ideal for characterizing
overall physical PHY) layer per-
formance of your WLAN transmitter.
Evaluate your transmitter design
against the IEEE standards. Take
advantage of its standardized tests
to qualify parts or do acceptance
testing. Use the software for
manufacturing test; you can even
modify the pass/fail limits to add
some margin between what IEEE
requires and what test you do.
N4010A/89601A/89607A
combination
In the N4010A/89601A combination,
the N4010A can be used as a wire-
less connectivity test set to link with
other Bluetooth devices and check
for correct operation by making
parametric measurements on the
device under test. Use the 89601A to
extend the testing capabilities of
the N4010A by measuring and
graphically displaying modulation
quality of your Bluetooth signal.
With the N4010A and Option
89601A-B7R or 89607A software,
the N4010A/89601A/89607A
combination can be used to test and
troubleshoot WLAN modules and
devices. The N4010A with Option
89601A-B7R can be used for flexible
modulation analysis to quickly
locate design problems. The N4010A
with the 89607A software can be
used test WLAN modules to the
specifications set down in the IEEE
802.11b/g standards with one-
button pass/fail testing.
This combination can measure
active signals or signals captured in
the N4010A’s memory. The N4010A
or the N4010A/89601A combination
can examine active signals. Switching
between the two products is
facilitated by an easy disconnect/
restart menu selection in the
89601A user interface.
The 89601A/89607A software runs
on a PC connected to the N4010A
via LAN, USB, or GPIB and provides
hardware control, modulation analy-
sis, evaluation, and troubleshooting
along with complete results displays.
The controls and display of the
N4010A are disabled while operat-
ing the 89601A/89607A software.

Performance Summary
The following is a summary of the
features and capabilities provided
by the N4010A in combination with
the 89601A software. These are
nominal values and are not
warranted.
Frequency range
Option N4010A-101 or 102 2.381 to 2.519 GHz (for 22 MHz span)
Center-frequency tuning resolution 1 MHz
Frequency span range < 10 kHz to 22 MHz
Frequency points per span
Calibrated points 51 to 102,401
Displayable points 51 to 131,072
Resolution bandwidth (RBW)
The range of available RBW choices is a function of the selected
frequency span and the number of calculated frequency points.
Users may step through the available range in 1-3-10 sequence
or directly enter an arbitrarily chosen bandwidth.
RBW range < 100 Hz to > 1.68 MHz
RBW shape factor
The window choices below allow you to optimize the RBW shape as
needed for best amplitude accuracy, dynamic range, or response to
transient signal characteristics.

Time and Waveform Time record characteristics
In the 89601A software, measurements are based on
time records (for example, blocks of waveform samples
from which time, frequency and modulation domain data
is derived.) Time records have these characteristics:
Time record length = (number of frequency points – 1)/span,
with RBW mode set to arbitrary, auto-coupled
Time sample resolutions = 1/(k x span)
Where k = 1.28 for time data = zoom
Time capture characteristics
In time capture mode, the 89601A software captures
the incoming waveform in real time (i.e. gap free)
into high speed time capture memory. This data may
then be replayed through the software at full or
reduced speed, saved to mass storage, or transferred
to another software application.
When post-analyzing the captured waveform, users
may adjust measurement span and center frequency
in order to zoom in on specific signals of interest, as
long as the new measurement span lies entirely
within the originally captured span.
Time capture memory size 500 ksamples (complex samples for spans
≤5 MHz; real samples for spans > 5 MHz)
Time capture length versus span 5 ms, 5 MHz < span ≤22 MHz
50 ms, spans ≤5 MHz

Software Interface
The 89601A software appears to
other Windows® software as an
ActiveX® object. Implemented
according to the industry-standard
Component Object Model COM), the
software exposes a rich object model
of properties, events, and methods,
as fully described in the 89601A
documentation.
Software development environments
that are capable of interacting with
COM objects include Agilent VEE,
Microsoft® Visual Basic®, Microsoft
Visual C++®, MATLAB®, National
Instruments® LabVIEW, and others.
In addition, many end-user applica-
tions are able to interact directly
with COM objects using built-in
macro languages such as Visual
Basic for Applications VBA). For
example, in Microsoft Excel®, a VBA
macro could be used to set up the
instrument, collect the measurement
data, and automatically graph the
results.
Macro language
The 89601A’s built-in Visual Basic script interpreter allows many
types of measurement and analysis tasks to be easily automated.
Scripts may be developed using any text editor, or may be recorded
automatically from a sequence of menu selections. Completed
scripts may be named and integrated onto the analyzer’s toolbar,
allowing them to be launched with a single button press.
Remote displays
To operate the 89601A/N4010A combination or view its displays
from a remote location, the use of commercially-available remote
PC software such as Microsoft NetMeeting®or Symantec
pcAnywhere®is recommended.
Remote programming
Beginning with Microsoft Windows NT®4.0, COM objects on
one PC are accessible from software running on another PC.
This capability, known as Distributed COM (DCOM), makes
the 89600 object model fully programmable from any other
PC having network connectivity to the N4010A’s host PC.
File formats
For storage and recall of measured or captured waveforms,
spectra, and other measurement results:
ASCII Tab-delimited (.txt), comma-delimited (.csv)
Binary Agilent standard data format (.sdf, .cap, .dat)
Binary Agilent E3238 time snapshot (.cap) and time
recording (.cap) files under 2 Gsa in size.
No additional calibration.
MATLAB 5 MAT-file (.mat)
Source
In source mode the 89601A software can control a signal
generator via GPIB or LAN. Control is provided via the
VSA GUI. Frequency and level control of CW signals is
provided. Arbitrary signals may be downloaded from the
time capture memory to the signal generator for replay.
The same time record may be played over and over
contiguously. A window function can be applied to
smooth start-up and finish of replay.
