  • Vector Modulation Analysis Software MX280005A Vector Signal Analyzer Applications Application Note
    Application Note Vector Modulation Analysis Software MX280005A Vector Signal Analyzer Applications For use with Anritsu Spectrum Analyzers Supporting Option 128 Introduction The Vector Signal Analyzer (VSA) is a PC-based software program which performs measurements on digitally modulated signals. An Anritsu hardware receiver/analyzer is first used to convert the RF signal into its complex baseband components. These components are referred to as I/Q signals where ‘I’ is the in-phase (phase reference) and ‘Q’ is the quadrature signal (90° out of phase). The captured I/Q files are then transmitted to the PC for various measurements relating to signal quality. This application note provides a high level overview of the demodulation process as well as insights that can be made from the analysis process. Anritsu’s VSA can be used both for design validation as well as for the investigation of problems such as component degradation, RF channel impairments, and interference. I/Q Conversion Process Information is encoded into the RF signal by modulating the RF carrier. Once received, each signal is digitized into a bit pattern which in turn is decoded by the receiver. Figure 1 shows an example of a quadrature phase shift key (QPSK) signal. Since there are four possible states in a QPSK signal, each state (or symbol) requires two bits to determine its position in the I/Q plane. Higher orders of modulation such as 8PSK or 16PSK require more bits per symbol. More information is carried with these modulations at the expense of a higher susceptibility to bit error rates. The demodulation process begins after the transmitted RF signal is first down-converted to a lower, intermediate frequency (IF), filtered, and presented to an analog-to-digital converter (ADC) in the receiver.

  • Agilent Vector Signal Analysis Basics
    Agilent Vector Signal Analysis Basics Application Note 150-15 Chapter 1 Vector Signal Analyzer This application note serves as a primer on the vector signal analyzer (VSA). This chapter discusses VSA measurement concepts and theory of operation; Chapter 2 discusses VSA vector-modulation analysis and, specifically, digital-modulation analysis. Analog, swept-tuned spectrum analyzers use superheterodyne technology to cover wide frequency ranges; from audio, through microwave, to millimeter frequencies. Fast Fourier transform (FFT) analyzers use digital signal processing (DSP) to provide high-resolution spectrum and network analysis, but are limited to low frequencies due to the limits of analog-to-digital conversion (ADC) and signal processing technologies. 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. VSAs combine superheterodyne technology with high speed ADCs and other DSP technologies to offer fast, high-resolution spectrum measurements, demodulation, and advanced time-domain analysis. A VSA is especially useful for characterizing complex signals such as burst, transient, or modulated signals used in communications, video, broadcast, sonar, and ultrasound imaging applications. Figure 1-1 shows a simplified block diagram of a VSA analyzer. The VSA implements a very different measurement approach than traditional swept analyzers; the analog IF section is replaced by a digital IF section incorporating FFT technology and digital signal processing. The traditional swept-tuned spectrum analyzer is an analog system; the VSA is fundamentally a digital system that uses digital data and mathematical algorithms to perform data analysis. For example, most traditional hardware functions, such as mixing, filtering, and demodulation, are accomplished digitally, as are many measurement operations.

  • Spectrum Analysis Back to Basics
    1 This presentation is intended to be a beginning tutorial on signal analysis. Vector signal analysis includes but is not restricted to spectrum analysis. It is written for those who are unfamiliar with spectrum analyzers and vector signal analyzers, and would like a basic understanding of how they work, what you need to know to use them to their fullest potential, and how to make them more effective for particular applications. It is written for new engineers and technicians, therefore a basic understanding of electrical concepts is recommended. We will begin with an overview of spectrum analysis. In this section, we will define spectrum analysis as well as present a brief introduction to the types of tests that are made with a spectrum and signal analyzer. From there, we will learn about spectrum and signal analyzers in terms of the hardware inside, what the importance of each component is, and how it all works together. In order to make measurements on a signal analyzer and to interpret the results correctly, it is important to understand the characteristics of the analyzer. Spectrum and signal analyzer specifications will help you determine if a particular instrument will make the measurements you need to make, and how accurate the results will be. New digital modulation types have introduced the necessity of new types of tests made on the signals. In addition to traditional spectrum analyzer tests, new power tests and demodulation measurements have to be performed. We will introduce these types of tests and what type of instruments that are needed to make them.
