Webinar: New Insights Into the Dynamic Behavior of RF Systems Using Realtime Spectrum Analysis

In modern spectrum analyzers, digital signal processing results in blind time after every sweep or data capturing procedure. In many applications, vital information is lost due to these blind slots. Therefore, for their development and optimization tasks, designers of synthesizers, radar systems and other transmitters not only need spectrum analyzers, they also need instruments with real-time signal processing capability or a spectrum signal analyzer combined with a realtime spectrum analyzer.

Realtime Spectrum Analyzers for Spurious Detection

A spur in electronics and frequency terms is a signal (normally narrow band but could be modulated) that normally is an unwanted product or side effect of a system that has been designed to perform another function. e.g. a mobile phone transmitter is required to transmit information on a specific band, but may as a side effect transmit signals that are also not wanted.

These unwanted spurs cause many issues for both the system they may be generated in, or other systems that may pick up the spurs and be a victim of their presence. Spurs may be out of the immediate band of interest and affect other neighbouring carriers or transmitters. Conversely spurs may be generated in the band of interest for the device being tested and these may significantly affect the transmit signal quality (EVM) and/or the receiver sensitivity of a system.

Such spurs are exhaustively searched for during design, verification test, EMC or other regulatory testing to prove a product complies with CE marking regulations as well as functions to its own manufacturers specification.

What are Realtime Spectrum Analyzers?

Darren Tipton of Rohde and Schwarz UK talks to Radio-Electronics.com and investigates what realtime spectrum analyzers are and how they can be used to find signals other analysers cannot see.

Spectrum analysers are devices that allow us to look at signals in the frequency domain rather than in the time domain. They are frequency selective devices that can be used to analyse characteristics of wanted signals, such as channel power, bandwidth, level and also unwanted characteristics of signals such as unwanted side band power, spurious or other interference.

In many cases a spectrum analyzer can be used to gain more information about a signal such as its phase. Such instruments are normally called vector signal analysers due to this added capability and they are able to perform for example modulation quality or frequency vs time measurements on signals by capturing the signal and post processing it.

In this short article we will discuss the differences between swept and real time spectrum analysers as well as what real time means and what advantages or disadvantages it has over traditional methods.
