Unless your background is in ac power, it’s possible you haven’t run into the term triplen harmonic. Triplen harmonics have to do with the third harmonic. Even-numbered harmonics do not normally exist in power systems due to symmetry between the positive and negative halves of the ac cycle. It is the odd-numbered harmonics that engineers […]

FPGA-based instruments: Inside the Moku benchtop test gear
The roots of the venerable Moku:Lab, Moku:Go and Moku:Pro test gear from Liquid Instruments can be traced back to a sophisticated interferometer set to orbit the earth. As part of his PhD work, Liquid Instruments CEO Daniel Shaddock documented the design of the control system for the LIGO mirror, which had to be stabilized at […]

Moku:Go is a software-enabled hardware platform that can fit in a backpack. It was designed for portability, flexibility and durability, to take not just […]
Book Review: Create Your Own EMC Troubleshooting Kit
Create Your Own EMC Troubleshooting Kit (Volume 1): Essential Tools for EMC Troubleshooters by Kenneth Wyatt shows you the tools you need to start tackling interference problems. Tracking down and mitigating electrical interference isn’t black magic, though some would have you believe that. Armed with some knowledge on how signals travel and with the right […]
Getting familiar with work-at-home instrumentation
The rise in social distancing has fostered a need for professional-grade test instruments that function as well at home as in the lab. David Horn | Digilent The events that have unfolded across the world since the beginning of 2020 have turned the global marketplace upside down. Few industries have felt this seismic shift as […]
Pocket-sized USB spectrum analyzers address emerging millimeter-wave apps
The Spectrum Master MS2760A ultraportable spectrum analyzer series now has extended broadband frequency coverage from 9 kHz – 170 GHz, as well as a new series of higher sensitivity models – the Spectrum Master MS2762A – with coverage from 6 GHz to 170 GHz for the most demanding sensitivity requirements. This family of tablet-driven, pocket-sized […]
Economical real-time spectrum analyzer monitors wireless signals in real time
The compact ThinkRF R5x50 Real-Time Spectrum Analyzer series are designed to monitor wireless signals in real-time rather than via progressive scan as with most common spectrum analyzers. Real-time analysis is essential for observing intermittent or frequency-hopped signals. Sleeker, lighter weight, and quieter than their predecessor models, the R5550 and R5750 analyzers offer improved spectral performance, […]
Rugged real-time spectrum analyzer/RF recorder works up to 20 GHz
The Spectran XFR V5 PRO Real-Time Spectrum Analyzer is a portable, rugged RF detection device designed to capture even the briefest signal transmissions. Its rapid signal acquisition scans a 20-GHz bandwidth in less than 20 msec, making it the world´s fastest counter-surveillance receiver. The instrument’s internal GPS also indicates the precise location of the measured […]
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 […]
Compact 6 GHz USB RF vector spectrum analyzer
The Triarchy Technologies VSA6G2A Vector Spectrum Analyzer is an economical tool that plugs into the USB port of a PC and is controlled with the provided PC application software. It offers almost all the functionality of a benchtop spectrum analyzer. Its frequency range of operation is from 100 Hz to 6.2 GHz, with an amplitude […]
