Technical Overview

Basic vector signal analysis (Option 200) provides the foundation of the tools and user interface that make up the 89600 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 the 89600 VSA software 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 200.

Hardware connectivity, now part of option 200, allows the 89600 VSA software 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 SSA, is also part of Basic VSA option 200. 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, the 89600 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.

The 89600 VSA software 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, the 89600 VSA software is uniquely suited to provide signal analysis for these complex systems.

The 89600 VSA software running on a PC uses a measurement “front-end” or data acquisition subsystem to provide formatted sampled data. The front-end 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, the 89600 VSA software is able to perform all vector and modulation analysis functions.

Analysis and Troubleshooting

Find the root cause of signal problems with advanced troubleshooting tools

Quantify spectral performance with high-resolution FFT-based measurements and a rich set of markers. Analyze time domain signal quality using pulse-timing features, robust trigger controls, CCDF, and more. Use analog demodulation to characterize AM, FM and PM behavior.

Complex stimulus-response measurements enable plotting of one signal versus another for results like AM/AM, AM/PM and gain compression. Automatic time alignment, amplitude normalization and phase error compensation greatly simplify measurement setup.

As the industry’s only solution to correlate baseband and RF signals, the 89600 VSA software is ideal for characterizing envelope tracking power amplifier and power supply designs.

Catch short-lived signal events using sophisticated displays and triggering

The digital persistence, cumulative history and spectrogram displays are useful for viewing signal amplitude and frequency behavior over time and identifying infrequently occurring events.

Capture elusive signals with flexible magnitude and external triggers, as well as frequency mask trigger (FMT) with real-time enabled UXA, PXA and MXA signal analyzers.

Initiate measurements or recordings based on trigger conditions to analyze and thoroughly characterize dynamic signals. Time qualified trigger may be combined with FMT and IF magnitude triggers.

Display unlimited traces simultaneously to gain greater clarity

Pinpoint problems with arbitrary arrangement and sizing of trace windows. You can assign any measurement to any trace, as well as unlimited markers per trace. Optimize the trace window shape to see the most data in each trace.

A docking manager tool lets you position traces anywhere within the 89600 VSA software display window. Multiple display windows can be created to manage a large number of results or take advantage of multiple monitors.

Record and analyze your signals in detail

Especially useful in early R&D, you can capture transient events, compare signal outputs after design iterations, or share the signal for collaborative analysis with remote colleagues. Additional tools, like overlap processing, let you effectively “slow down” the apparent measurement for more in-depth analysis.
