How to Evaluate and Troubleshoot Wireless Signals with 89600 VSA Software
If you are working with wireless signals in research and development (R&D), you need a reliable and flexible tool for analyzing and demodulating them. Whether you are dealing with 5G, IoT, radar, or any other signal standard or modulation type, you want to gain deeper insight into the frequency, time, and modulation domains of your signals. That's where the 89600 VSA software comes in.
The 89600 VSA software, also known as PathWave 89600 VSA, is a comprehensive set of tools for demodulation and vector signal analysis. It is PC-based, supporting numerous hardware measurement platforms like Keysightâs spectrum analyzers. It can also connect directly to data sources such as simulation software or recorded files. With the 89600 VSA software, you can:
Pinpoint signal problems in time, frequency, and modulation domains
Measure a broad range of signals including 5G, IoT, cellular, WiFi, aerospace, defense, satellite, and more
See through complex signals with customizable measurement displays and unlimited traces
Verify your designs throughout the design cycle with consistent and comparable results
Stay up to date with the latest signal standards and modulation types
In this article, we will review some of the key features and capabilities of the 89600 VSA software and how it can help you optimize your wireless signal analysis.
One of the new features of the 89600 VSA software is the PowerSuite measurements. This feature allows you to measure in-band signal quality and out-of-band emissions as a one-stop shop. You can perform single and multi-carrier Adjacent Channel Power (ACP) and Spectrum Emission Mask (SEM) measurements with presets for 5G base station conformance test with pass/fail results. You can also configure the measurements for any signal type (not limited to 5G) and use similar settings and results as PathWave X-Series Measurement Applications (X-Apps). The PowerSuite measurements can be used with any hardware or data source supported by the VSA software and can apply noise correction with PXI Vector Transceiver (VXT) and X-Series Signal Analyzer (X-SA) hardware for best dynamic range[^1^].
Improved EVM Floor with Cross-Correlated Measurements
Another feature that can enhance your signal analysis is the cross-correlated EVM measurement. This feature allows you to eliminate the effects of receiver noise in your estimates of Error Vector Magnitude (EVM) using two receivers. This can improve your EVM floor by 6-20 dB depending on your signal bandwidth and hardware configuration. The cross-correlated EVM measurement is available for 5G NR and high-speed wireless LAN measurements[^1^].
Event-Based User Actions
The 89600 VSA software also offers advanced triggering based on signal analysis metrics. You can choose a metric such as EVM, frequency error, etc., a condition by which an action should occur, and what happens when the metric meets that criteria. For example, you can trigger a capture when the EVM exceeds a certain threshold or save a file when the frequency error is within a certain range[^1^]. This feature can help you automate your measurements and focus on the events that matter most.
Latest 5G Capabilities
The 89600 VSA software keeps up to date with the latest 5G New Radio (NR) measurement extension enhancements. Some of the recent additions include:
Cross-correlated EVM with the 5G NR measurement extension
5G Non-Terrestrial Network (NTN) support as per release 17 of 3GPP
1024 QAM Test Models per Release 17
Support for additional antenna types for beamforming
Support for 32 component carriers[^1^]
With these features, you can stay ahead of the curve and test your 5G signals according to the latest specifications.
