KickStart 2.1 instrument control software enables quick test setup and data visualization when using single or multiple instruments. This software is now available for use with a broader range of Keithley instruments and for the first time can be used with Tektronix mid-range oscilloscopes. Included with the base KickStart package are four instrument apps: I-V […]
Hot topic: How to measure plasma in a fusion reactor
The International Thermonuclear Experimental Reactor (ITER) tokamak is an experimental machine designed to harness the energy of fusion. ITER will be the world’s largest tokamak, with a plasma radius of 6.2 m and a plasma volume of 840 m³. The heart of a tokamak is its doughnut-shaped vacuum chamber. Here, under the influence of extreme […]
Op-amps and their most important parameters
The operational amplifier (op-amp) has been one of the most successful integrated circuits. A type of differential amplifier with high gain, the differential inputs and single output enable this small, inexpensive IC to use negative feedback in a wide variety of applications, in which its gain (hundreds of thousands of times higher than the difference […]
Academic discount program supports lab upgrades in educational institutions
A special program is designed to encourage academic institutions to upgrade their laboratory instrumentation. The Vitrek Academic Discount Program is designed to ease the burden of providing researchers and students with the latest in high-performance test equipment by offering reduced prices on Vitrek equipment to qualified university, college and research laboratories. “Our premier instruments are […]
Remote Communication with USBTMC
Simple connections employing USB can replace more expensive GPIB setups in test instrumentation. Aaron Fernando, B&K Precision Corp. Engineers from a variety of industries use USB and USBTMC (USB Test & Measurement Class) to remotely control test and measurement instruments from a host computer. It is useful to compare USBTMC to the widely used GPIB […]
Testing LVDS devices at the margins with an AWG
Advanced arbitrary waveform generators have simplified the testing associated with communications over low-voltage differential signaling lines. Chris Loberg | Tektronix First introduced in 1994, low-voltage differential signaling (LVDS) has gone on to become widely used in products such as LCD panels, automotive infotainment systems, industrial cameras and machine vision, notebook and tablet computers, communications systems, […]
Test instruments that aid PCB repair tasks
Basic tools such as DMMs and oscilloscopes may be the only test gear needed for small printed circuit board repairs, but it pays to know when automated systems would be a better choice. Alan Lowne | Saelig Co. Inc. PCBs are more complicated to repair today than even a few years ago. Manufacturing mistakes and […]
Web-based jitter measurement utility gives product designers critical timing test results in minutes
The new Jitter Measurement Utility is a web-based, fully automated tool that enables designers to quickly and easily evaluate the jitter and phase noise performance of their custom clock configurations without using their own test equipment. “The need for higher timing performance is being driven by the introduction of new technologies such as 5G, mmWave, […]
Basics of cavity resonators
Experimenters beware! If you think it might be instructive to dismantle a microwave oven and power up the magnetron to make a space gun, don’t do it. A microwave gun (called a magnetron) in a state other than as manufactured has numerous potential hazards. (Nevertheless, you can find a lot of YouTube videos describing exactly […]
Test gear rapidly detects, locates, report optical fiber breaks up to 100 m away
A new testing solution detects problems within optical fibers. AddOn’s EON-NSV-OTDR devices rapidly locate and report any faults in an optical fiber link of a communication network – saving service providers time and money by allowing them to quickly address the root cause of any issues. The detection of problems within optical fibers is critical […]
