Multifunction test instruments connect to PCs via USB/Wi-Fi
Digilent Inc.’s OpenScope: Open-source PICMZ All-in-One Instrumentation Device is available for immediate shipment worldwide from Digi-Key Electronics, a global electronic components distributor, the companies announced today. The OpenScope MZ is a portable multi-function programmable instrumentation module. What does that mean? It is a device that connects to a computer (through Wi-Fi or a USB cable) that allows […]
VIDEO: Tektronix RSA306B PC-Based Spectrum Analyzer
A new Tektronix PC-based spectrum analyzer is described and configured to a Windows laptop computer, and its use is demonstrated. Hi and welcome to our 68th Test and Measurement video. Today we’ll do an overview of the Tektronix amazing breakthrough RSA306B PC-based spectrum analyzer. To generalize, the spectrum analyzer is similar to the oscilloscope, but […]
Dealing with and displaying power-line harmonics
Harmonics are waveforms that may accompany a periodic fundamental (also known as the first harmonic) in a divergent infinite series. When they arise, their frequencies are integer multiples of the fundamental. If this fundamental is 60 Hz, the second harmonic is 120 Hz, the third harmonic is 180 Hz, the fourth harmonic is 240 Hz […]
Testing operational amplifiers
Because it is able to function in so many diverse ways, the op-amp can be the defining element in electronic circuits of any complexity. Applications go far beyond amplification. Because they are near-perfect dc amplifiers, op-amps are suitable for filtering, signal conditioning, and for performing such mathematical operations as addition, subtraction, differentiation, and integration. Op […]
The modern economics of renting test instruments
The development of online instrument exchanges puts a new wrinkle into how to get the optimum use of test gear. LEE TESCHLER EXECUTIVE EDITOR When a project comes up that involves expensive test gear like gigahertz-range signal analysis, statistics from the Equipment Leasing & Finance Foundation show this kind of instrumentation is increasingly acquired through […]
Laser power meter can display results over Bluetooth
Gentec Electro Optics, Inc. is proud to present BLU, the first series of wireless laser power meters, at the LASER World of PHOTONICS trade show in Munich. This new product line combines a detector and a Bluetooth-enabled meter unit in a convenient, all-in-one product. Using the free Gentec-EO BLU app, measuring results can be displayed […]
Test gear for wireless communications systems
Various types of wireless communications are characterized by the distances that they can travel. Short distances are conveniently spanned using Bluetooth technology, occupying the radio frequency spectrum from 2.4 to 2.485 GHz. Bluetooth was originally developed to replace RS-232 cabling and it is used to link fixed and mobile devices. It has become ubiquitous in […]

Test & Measurement Handbook 2017
SEEN A GHOST? BLAME ELECTROMAGNETIC FIELDS WE’D like to think that the average viewer who tunes into a TV show on the SciFy channel called Ghost Hunters might get a laugh out watching investigators prowl around places that are reported to be haunted. But the show participants seem to be completely serious and unconcerned about…
