Some 600 companies exhibited at the recently concluded International Microwave Symposium in Phoenix. Microwave design is an instrumentation-intensive endeavor, so a lot of show floor space was devoted to new developments in test gear. Here are a few things in that area that caught our attention. Garbled signals, instruments to the rescue National Instrument’s RFIC […]
By Lisa Clark Before we differentiate a spectrum analyzer and a network analyzer, it is important to understand what these two instruments are, and what function they perform. Thus, we give a basic overview of the two devices and their basic mechanism: Spectrum Analyzer The spectrum analyzer is an electronic device that is used for […]
Oliver Heaviside’s life, spanning the years 1850 to 1925, began and ended in squalid surroundings. He was never entirely free of the dark melancholy that characterized his private as well as public persona. Beyond a little primary schooling, he was self-educated. His reading of James Clerk Maxwell’s Treatise On Electricity And Magnetism was a revelation. […]

A new power analyzer combines power measurements with features of a touch-driven oscilloscope. The Keysight IntegraVision power analyzer targets engineers who need dynamic views of current, voltage and power so they can see, measure and prove the performance of devices such as power inverters or converters, universal power supplies, battery systems, vehicle and aircraft power systems, lighting systems/electronic ballasts and […]
The DMM7510 7½-Digit Graphical Sampling Multimeter integrates a high-accuracy digital multimeter, a digitizer for waveform capture, and a capacitive touchscreen user interface. The instrument is a precision multimeter with selectable resolution levels from 3½ to 7½ digits and provides DC accuracies typically only found in metrology-grade instrumentation. It has a 14 ppm basic 1-year DCV […]
Here are some of the most popular topics in test & measurement being discussed in our EDAboard.com sister site. Measuring antenna radiation — I had a problem measuring and understanding the problem of quantifying radiation patterns. I am working on a dongle application. How do I measure and test my simulation value range and what […]
Here are the most popular threads on EDAboard this week pertaining to test and measurement topics: Measuring an RF transceiver: I have a low-noise mixer IF amplifier and IF filter on the PCB. I want to measure signal power, return loss, insertion loss on the PCB. What is the best solution for this? Should I […]
