The compact ThinkRF R5500 Real-Time Spectrum Analyzer series is designed to monitor and analyze wireless signals in real-time and not progressively scanned like most common spectrum analyzers. Real-time analysis is vital for being able to observe intermittent or frequency-hopped signals. The R5500 series comes in three models to cover 8, 18, or 27-GHz signals. They […]

Modules let spectrum analyzers serve as I/Q sources within open-source GNU radio apps
GNU Radio modules for the BB60C and SM200A spectrum analyzers allow the analyzers to be used as I/Q sources from within GNU Radio, as blocks in a flowgraph, components of a hierarchical block, or called from a script. According to Roger Rush, lead developer on the project, “Signal Hound and GNU Radio share a software-based […]
USB spectrum analyzer portfolio now includes 13 GHz and 18 GHz models
The RSA500 family of rugged, battery-powered USB-based spectrum analyzers now includes the RSA513A and RSA518A offering 13-GHz and 18-GHz frequency range respectively. Along with their higher frequency support, these instruments provide the ability to stream I & Q data for customers to perform analysis consistent with software-defined radio functionality. Delivering performance and functionality equal to […]
Interactive debugging on a budget
The cost of undertaking multi-domain debugging has come down. New instrumentation can time-correlate RF and embedded signals to let designers quickly uncover the root causes of knotty problems. CHRIS ARMSTRONG, RIGOL TECHNOLOGIES INC. Examine a typical device that is part of the Internet of Things and you’ll likely find a product that combines RF, digital, […]
You passed: Getting products through EMC/EMI compliance tests
Pre-compliance tests run in your own lab can avoid bad news when products go into formal conformity checks. DYLAN STINSON, TEKTRONIX INC. EMI regulations are in place to ensure reliability and safety for users of electrical and electronic equipment. With few exceptions, any product emitting or susceptible to electromagnetic interference must be certified for EMI […]
Real-time spectrum analyzers available in 3.0 GHz and 4.5 GHz models
The New RSA3000 Real-Time Spectrum Analyzer targets applications that don’t require the high performance or standard options of the performance RSA5000 Series. Price sensitive engineers looking to bring Real-Time Analysis to their test bench can now get an upgradable, powerful solution at an exceptional entry price. Available in 3.0 GHz and 4.5 GHz models with […]
Real-time spectrum analyzers come in 3.2-GHz and 6.5-GHz models
The New RSA5000 Real-Time Spectrum Analyzer provides Resolution Bandwidth (RBW) down to 1 Hz, a noise floor as low as -165 dBm, and a full-span sweep as fast as 1 msec. In addition, the analyzer features up to 40 MHz of real-time bandwidth, a minimum probability of intercept (POI) of 7.45 µsec, seven rich visualization […]
Measuring with spectrum analyzers
Modern bench-type and even hand-held oscilloscopes have spectrum analysis capability, providing great added versatility. They can view in rapid succession (or even simultaneously in split-screen format in a mixed-domain instrument) time domain and frequency domain displays of the same signal. Fourier theory tells us that any signal or function in the time domain can be […]
Real-Time 27-GHz spectrum analyzers are PC controlled
Saelig Company, Inc. announces the availability of the compact RTSA7550 Real-Time Spectrum Analyzer – a powerful, full-featured spectrum analyzer designed to analyze wireless signals in real-time (not progressively scanned). This is essential for seeing intermittent and frequency-varying signals. The Model RTSA7550 has all the standard features of a conventional spectrum analyzer such as frequency controls, […]
Handy test equipment for troubleshooting
Not all test equipment needs to be expensive. Here are a few helpful tools that won’t break the bank. Electricians doing residential, commercial or industrial work need to know with absolute certainty whether a wire or terminal is live and whether a given piece of electrical equipment is energized at the power input terminals. Usually, […]
