Wireless Communication Analyser WCA200A Series

The WCA200A Series Wireless Communications Analysers were developed 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 synchronised RF or base band signal into memory, and they can analyse 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.

Features & Benefits

• Multi-domain analysis enables fast, complete signal analysis in frequency, time, code and modulation domains — without making multiple measurements
• Extended Memory enables 10 seconds of 3G and 3.5G signals to be captured, ensuring all the necessary information is available to make a complete analysis of the signal
• Frequency Mask Trigger – Available only from Tektronix – Makes it easy to capture fast, transient, or intermittent signals that swept spectrum analyzers would miss
• Fast and accurate measurements at the touch of a button
• Spectrogram provides a revealing picture of RF signal frequency and amplitude behavior over time – not possible with a swept spectrum analyser
• Codogram provides a simple, graphical means of analysing code power vs. time
• W-CDMA Compressed Mode enables analysis of handovers between W-CDMA and GSM
• ACK/NACK and CQI analysis for HSDPA uplink (Requires Option 27 and 23)
• Differential I/Q inputs enable straightforward analysis of differential baseband I and Q signals
• Fast measurement speed and exceptional accuracy improve production throughput without affecting yield
• Versatile general demodulation capabilities ranging from BPSK to 256QAM, as well as selectable filters allow analysis of non-standard signals
• One instrument, practical and useful every day, to cover all your spectrum and vector analysis needs

Characterisation

The WCA230A and WCA280A provide design engineers with all the measurement capabilities needed to fully characterise devices in an accurate, efficient manner – ensuring a complete picture of the device’s capability. 2G, 2.5G, 3G, 3.5G Modulation Analysis Software on the WCA200A Series offers modulation analysis software that provides one-button measurement routines that quickly and accurately perform measurements that conform to the relevant industry standards – W-CDMA, HSDPA, GSM/EDGE, cdma2000 1x, 1xEV-DO, and TD-SCDMA.

In W-CDMA Compressed Mode the WCA200A Series, with its unique ability to analyse W-CDMA compressed mode, allows engineers to quickly and easily monitor their device during the complex handover process between W-CDMA and GSM.

By providing differential I/Q inputs, the WCA200A Series is the only product in this class that addresses the increasingly common need of 3G UE designers to directly measure their differential I/Q signals. A 3D Graphical Display on the WCA200A Series is the only one-box solution that offers engineers extremely useful graphical representations, such as spectrogram and codogram, which give a complete picture of what is happening with the signal under test.

Troubleshooting Capabilities

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 analysers and vector signal analysers 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 3G or 3.5G 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 analyser that can trigger on any RF signal and seamlessly capture the full duration of the call set up into memory, enabling time-correlated multi-domain 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

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 SW is the only spectrum analyser 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 analysers. 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.
