LCR meter resolves inductance to 1 nH, capacitance to 0.01 pF

August 18, 2017 By Test and Measurement Editor Leave a Comment

Since its release in 2013, LCR-Reader has become a popular test and debugging tool for electronics development. It was important that the tool was offered at half price than its predecessor Smart Tweezers by reducing functionality and simplifying the operation of the device. On the contrary, LCR-Reader MP (Multi Purpose) offers many new features covering […]

mipi-rffe-2

by Mike Borsch and Mike Schnecker, ROHDE & SCHWARZ Modern transceivers often incorporate several parallel RF front ends whose control signaling can be sorted out with advanced instrumentation. The radio frequency (RF) front-end configuration in mobile devices continues to evolve and get better. The trend in mobile radio communications is toward complex multi-radio systems perhaps […]

DCR2U-critical-Mission-Power-Supply-small

by Gerald Hovdestad, Behlman Electronics Commercial-off-the-shelf power equipment can be an option for situations that normally demand specialized designs optimized for harsh conditions. A lot of DOD and industrial equipment is so specialized that it must be custom-developed – it just can’t be bought off-the-shelf. Ironically, there is a large array of commercial products that […]

How to test DC-to-DC converters

June 17, 2016 By Test and Measurement Editor 5 Comments

screen-shot-display--Chroma-63200A

by Larry Sharp, Chroma Systems Solutions, Inc. Functional and safety tests can show whether dc/dc converters perform the way their manufacturers claim they do. DC-to-DC converters (DC/DC) are devices used to convert one dc voltage to another. Users and manufacturers may characterize DC/DC converters by running a variety of tests. We’ll describe several here, but […]

1-KHZ-TRAIN-of-sync-pulses-small

by Barrett Poe, Keysight Technologies, Inc. User interfaces have become more advanced and measurements more automated – and less tolerant of improper measurement setups. Long before every oscilloscope carried an autoscale button, and before touch-screen triggering was a gleam in someone’s eye, aspiring engineers would need to manually adjust settings for the time base and […]

One hidden oscilloscope spec that really matters

June 17, 2016 By Test and Measurement Editor Leave a Comment

Passband-Ideal-v-Non-ideal

by Ben Robinson, National Instruments Corp. Bandwidth isn’t necessarily the primary spec for evaluating how well a scope can display signals of interest. Oscilloscope vendors, National Instruments included, like putting big numbers on the front panels of their instruments to tell you how much better they are than competitors. Bandwidth, sample rate, and sometimes bits-of-resolution […]
