Basic vector signal analysis (Option 89601200C) provides the foundation of the tools and user interface that make up PathWave Vector Signal Analysis (VSA) software. Explore virtually every facet of today’s most complex signals with views of time, frequency and modulation domains. Benefit from the flexible GUI capabilities: arbitrary arrangement and sizing of unlimited display traces, each with unlimited markers. Powerful display formats, signal recording and playback, and detailed Help text provide the insight needed for analyzing signals.
Use PathWave Vector Signal Analysis (VSA) in simulation with sink and source components providing real-time, interactive analysis of results. Co-simulation is available with Keysight Technologies. Keysight EEsof EDA Advanced Design System (ADS) and SystemVue ESL as part of Option 89601200C.
Hardware connectivity, now part of Option 89601200C, allows PathWave Vector Signal Analysis (VSA) to be linked to over 45 Keysight instruments. Choose the right instrument for your application and apply vector signal analysis across your mixed signal design. Use the 89600 VSA software for consistent, comparable results at simulation, prototype and design-validation stages of development.
Power spectrum measurement, previously provided as Option 89601B-SSA, is also part of Basic VSA Option 89601200C. When used with PXIe VSA M9393A or M9391A, users can perform fast spectrum measurement. (Refer 5991-4582EN for more details.)
These options work together to provide a comprehensive set of tools for demodulation and vector signal analysis. These tools enable you to explore virtually every facet of a signal and optimize your most advanced designs. As you assess the tradeoffs, PathWave Vector Signal Analysis (VSA) helps you see through the complexity.
Vector signal analysis
Today’s wide-bandwidth, vector-modulated (also called complex or digitally modulated), time-varying signals benefit greatly from the capabilities of FFT analysis and other DSP techniques. Vector signal analysis offers fast, high-resolution spectrum measurements, demodulation, and advanced time-domain analysis. It is especially useful for characterizing burst, transient, or modulated signals used in communications, video, broadcast, radar, and ultrasound imaging applications.
PathWave Vector Signal Analysis (VSA) is fundamentally a digital system that uses data and mathematical algorithms to perform analysis. All it requires is sampled data from an instrument, software, or digital bus. As a larger portion of wireless designs becomes digital, PathWave Vector Signal Analysis (VSA) software is uniquely suited to provide signal analysis for these complex systems.
PathWave Vector Signal Analysis (VSA) running on a PC uses a measurement “frontend” or data acquisition subsystem to provide formatted sampled data. The frontend performs the following functions: connection to the device under test, signal digitizing, signal capture capability, and data transfer to the PC in a sequential stream of data blocks. Once the data blocks are available, PathWave Vector Signal Analysis (VSA) software is able to perform all vector and modulation analysis functions.
