Articles - Measurement - 9

I am continually amazed at how the pioneers of electronics, and microwaves in particular, did their research and development with little or no test equipment. How can you design or repair anything without being able to measure key parameters? Yet ...

By Johann Zipperer Peter Weber, Texas Instruments. Electronic Specifier A novel approach to digitally measuring analog current could deliver greater accuracy at ultra-low powers Measuring current can be as simple as putting a shunt resistor in ...

Kenneth Wyatt EDN These unusual EMI sources may be used to perform pre-compliance testing (radiated or conducted immunity) to help determine the immunity characteristics of your circuits or product. Chattering Relay (120 VAC powered) - can produce ...

Dennis Seguine, Cypress Semiconductor Electronic Design Using a pseudorandom sequence (PRS) generator and some software, you can build a pink-noise generator (equal energy per octave) with 1 dB performance over the audio band, in addition to the ...

Tak Tsang, Agilent Technologies Machine Design It’s no secret that electrical overloads and physical abuse can shorten the life of a handheld meter. But some instruments can withstand far more mishandling than others. Today it is possible to ...

Described as The nerdiest thing you can put on your wrist.” The Oscilloscope Watch has the features of a modern watch (time, calendar, alarm, etc...) along with those of an oscilloscope, waveform generator, logic analyzer, protocol sniffer, ...

Karthik Kadirvel, Texas Instruments ECN Personal battery-powered devices range from single-cell devices such as cell phones to multi-cell devices such as electric cars. Range anxiety is a common issue among all battery-operated electronics. Users ...

Introduction In Industrial motor or servo control applications, accurate current measurement is a critical as part of the control loop. Not only has the current measurement need to be as accurate as possible, it also needs to be safe and reliable. ...

TIAs are the most powerful type of time measurement instruments. In addition to the functions provided by traditional “frequency counters”, “time interval counters” and “universal counters”, TIAs include new ...

Jason Seitz, Texas Instruments EDN In today’s industrial automation and process-control applications, sensors that measure process parameters such as pressure, temperature, toxic gas, and pH are abundant. These sensors make industrial ...
