Wireless Communication Analyzers

WCA230A • WCA280A

Trigger, Capture, Analyze

The WCA200A Series Wireless

Communications Analyzers were devel-

oped for designers and manufacturers

of wireless communications devices. The

WCA200A Series can selectively trigger

on frequency domain events that no

other instrument can trigger on, they

can capture a seamless record of time

synchronized RF or base band signal

into memory and they can analyze this

data. This analysis includes correlating

multiple domains, which allows developers

to observe system interactions and

behaviors, ensure proper operation and

rapidly troubleshoot problems with a

simple test set up.

Troubleshooting – Now it is Simple
to See What Couldn’t be Seen

Troubleshooting a design can be a

challenging, time-consuming task for

any engineer. The WCA200A Series is

designed to let you focus on the task at

hand, troubleshooting your design and

not spend your time learning specialized

test equipment or using external software

for post processing. The WCA200A

Series is designed to provide advanced

modulation analysis and troubleshooting

capability in an easy-to-use, one-box

solution, which allows you to use these

advanced troubleshooting tools without

having to become an expert on the

test equipment.

Frequency Mask Trigger – The ability to

trigger off any signal, either known or
unknown, in the frequency domain ensures
that signals which traditional spectrum
analyzers and vector signal analyzers would
miss can be captured and analyzed in all
domains – providing you with a complete
view of even the most random signals.

Long Acquisition Memory – Extended

memory enables 10 seconds of 3 G or 3.5 G
signals to be captured, ensuring all the
necessary information is available to make
a complete analysis of the signal.

Concurrent Multi-domain Analysis – The

WCA200A Series lets you perform simulta­neous measurements in the frequency, time,
code and modulation domains, which
enables simple, fast and complete analysis
of all complex RF signals without the need
for multiple and non-concurrent measure­ments. By removing the need for multiple
measurements, you can be sure that your
results correlate between domains, ensuring
accurate comparisons.

Simultaneous Analysis of UE and BTS
Interaction – When two WCA200A Series

instruments are synchronized, the unique
frequency mask trigger coupled with the
long memory capture enables the complete
call up set interactions between UE and
BTS be recorded so interoperability issues
can be identified.

Analysis of Dynamically Changing interactions
Between 3GPP Node-B and UE – The

WCA200A Series with HSDPA analysis
software is the only spectrum analyzer that
can trigger on any RF signal and seamlessly
capture the full duration of the call set up
into memory, enabling time-correlated multi­domain analysis views of the ACK/NACK
signal and dynamic changes in the RF signal
over time.

Ease of Use – The user interface of the

WCA200A Series was designed to ensure
that its advanced troubleshooting capabilities
are easy to use. As a result, you will spend
less time pondering operation and more time
troubleshooting the device under test.

Verification – Practical for
Everyday Use, the WCA200A
Series Lets You View Test Results
Sooner

When verifying your product, two critical

questions must be asked about your test

equipment: How quickly can I get the

results? How accurate are the results?

The WCA200A Series answers these

questions with a powerful combination of

speed and accuracy. Even when your test

challenges change day to day, the

WCA200A Series enables you to solve

your measurement challenges, quickly

and accurately.

Fast Power Measurements – Whether you are

making power calibration measurements on
a cell phone production line or testing the
ACLR performance of a PA to a 2G, 2.5G,
3G, or 3.5G standard, the WCA200A Series
offers not only exceptionally fast measure­ments, but outstanding accuracy as well,
thereby improving production throughput
without affecting yield.

Analysis of Complex and Dynamically
Changing RF Signals or Interactions Between
DSP Operations and RF Events – The

WCA200A Series with HSDPA analysis
software is the only spectrum analyzer that
can trigger on any RF signal and perform
multi-domain analysis of the dynamic
changes in ACK/NACK signals over time.

Reduced Test Setup and Cost – The

WCA200A Series removes the need for
test systems to include several different
analyzers. This one-box solution meets
all your demodulation requirements,
without sacrificing the traditional RF
performance that you need to satisfy your
RF test challenges.

Flexible Connectivity – The WCA200A Series

provides users with many different ways to
access their measurement results. Ethernet,
USB (2 ports), and GPIB ports are supplied
as standard, along with a floppy disk drive.
