Accurately Demodulate Satellite Communication Signals
Satellites that use higher frequencies and wider bandwidths require higher-order and more complex modulation techniques. As a result, you need to test and characterize components and systems more thoroughly to ensure that they meet requirements. As modulation becomes more complex, viewing a time-domain waveform or frequency spectrum and understanding or troubleshooting signal quality issues becomes increasingly challenging. Such challenges are particularly apparent for techniques using IQ modulation. Instead, use a vector signal analysis tool to demodulate the signals and display them as constellations.
Keysight PathWave Vector Signal Analysis (89600 VSA) software allows you to analyze the modulation accuracy. It provides insight into error vector magnitude (EVM), IQ offset, quadrature error, and gain imbalance measurements. In addition to the standard digital modulation schemes used in satellite communication, the software supports custom modulations for your satellite applications.
- Supports more than 40 digital modulation formats, including PSK, QPSK, QAM, FSK, VSB, custom APSK, SOQPSK.
- Perform digital modulation analysis on nonstandard user-defined IQ signals.
- Troubleshoot signals using modulation error analysis tools: EVM, IQ errors, and more.
- See through the complexity of custom orthogonal frequency-division multiplexing (OFDM) systems and handle a wide range of signals using a highly customizable parameter setup.
- Characterize signals and troubleshoot errors using flexible measurement displays.
- Evaluate single-input / single-output and multiple-input / multiple-output (MIMO) systems with channel, stream, and cross-channel measurements.
- Automate tests with SCPI or .NET programmability.
A Comprehensive Overview of Satellite Communication Modulation Techniques
As the demand for faster data throughput grows, satellite communications use complex modulation schemes to improve their spectral efficiency. In satellite communications, modulation techniques entail higher data rates and minimize nonlinear amplification in the radio-frequency power amplifier. Choosing the right modulation scheme depends on your communication channels, hardware limitations, and data throughput requirements. With flexible custom modulation software, you can save time on signal simulation and easily configure your signal analyzer for demodulation analysis.
This white paper discusses modulation techniques for modern satellite communications, from signal generation and signal analysis to how phase noise affects your modulation analysis.

PathWave VSA Custom OFDM Modulation Analysis Demonstration
Communications systems have widely accepted OFDM signals because of their inherent immunity to noise and efficiency in transmission. However, troubleshooting and analyzing these systems can be challenging, especially for new, custom, generic, or nonstandard OFDM formats. Spectrum analysis tools can measure simple parameters such as frequency, power level, and spectral mask, but most in-depth quality measurements require specialized tools, such as VSA tools that can work with custom OFDM systems.
PathWave VSA with Option BHF, custom OFDM modulation analysis, provides an easy-to-use interface to describe your generic and proprietary OFDM signals without developing any special software. Troubleshooting your designs has never been easier. PathWave VSA displays a channel’s error summary including details on EVM, frequency, symbol clock, and common pilot errors; plus IQ errors such as offset, quadrature errors, gain imbalance, and time skew.
