Trigger, Capture, Analyze

The WCA200A Series Wireless Communications Analyzers 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 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.

Characterization – The Versatile WCA200A Series Lets You See More of What is There

The WCA230A and WCA280A provide design engineers with all the measurement capabilities needed to fully characterize devices in an accurate, efficient manner – ensuring a complete picture of the device’s capability.

2G, 2.5G, 3G, 3.5G Modulation Analysis Software – 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.

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

Differential I/Q inputs – 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.

3D Graphical Display – 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 – 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 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 analyzer 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 – 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 SW 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.
