Testing Times Square on its busiest night

Testing Times Square on its busiest night
MATsolutions' insight:

 

It's not often that you have a large group of people huddled in one spot at one time. Times Square on New Year's Eve generates just the situation, with an estimate of 1 million people. Teams from Global Wireless Solutions got together and tested the cell phone service and data scores through the whole night to see how networks would handle the heavy traffic. 

 



Article Excerpt:

When the ball dropped on New Year's Eve, three teams from Global Wireless Solutions were testing carrier networks in New York's Times Square.


Sorry, Primary Kilogram, But We Are Dumping You

Sorry, Primary Kilogram, But We Are Dumping You
MATsolutions' insight:

 

After decades of research, the kilogram has been retired and replaced with a reproducible equivalent, the SI or International System of Units.  Now, none of the defining constants and primary standards are tied to a single physical artifact.

 



Article Excerpt:

The physical kilogram, the last of the physical primary-standard artifacts, has been made obsolete. The world’s metrology and standards organization voted to define all physical standards in terms of just seven universal constants.

Historic Vote Ties Kilogram and Other Units to Natural Constants 

Historic Vote Ties Kilogram and Other Units to Natural Constants 
MATsolutions' insight:

 

This historic move will inspire new technology and innovations along with more accurate measurements, and smaller costs to calibrating industrial processes and scientific instruments. 

 



Article Excerpt:

"A convocation of delegates representing 60 countries voted today in Versailles to implement the most significant change to the International System of Units (SI) in more than 130 years. For the first time, all measurement units will be defined by natural phenomena rather than by physical artifacts. The event was the 26th General Conference of Weights and Measures and was hosted by the International Bureau of Weights and Measures."

 


11 Myths About Formal Verification

11 Myths About Formal Verification
MATsolutions' insight:

Don't believe everything you may have heard about Formal Verification - especially if it is keeping you from using it. It can be very beneficial to use, so before avoiding it, read up on the myths and get to know the benefits. 



Article Excerpt:

"Formal verification, which uses mathematical analysis rather than simulation tests, has been available in commercial EDA tools for more than 20 years and in academia much longer. As with many new technologies, initial adoption was slow and limited to companies who had in-house formal experts. This has changed dramatically in the last dozen years or so. Almost every chip-development team makes some use of formal tools, and the market continues to grow. Nevertheless, some myths about formal persist, and they may still be deterring some engineers who could benefit from it. It’s time for the truth to be told."



Understanding oscilloscope bandwidth enhancement techniques

Understanding oscilloscope bandwidth enhancement techniques
MATsolutions' insight:

 

When you need your oscilloscope to have a higher bandwidth, it is beneficial to know the different techniques such as RIS, DSP boosting and Raw Hardware Performance that can help you. What technique do you like to use? 

 



Article Excerpt:

"Data communication rates have soared in recent years and there is every reason to believe that this trend will accelerate. Information speeds that were less than 1 Gb/sec have surpassed 10 Gb/sec. Optical communication is greater than 100 Gb/sec, with 1 Tb/sec down the road. RF wireless communications is in the mid-gigahertz range, and RF and optical communications comply with mandates by means of innovative types of modulation and low-amplitude signals. High-bandwidth oscilloscopes are required to debug these new system designs. As a result, oscilloscope designers are introducing instruments extending beyond 70 GHz."

Pro tip: 3 ways of automatically creating test scripts on Keithley instruments | Tektronix

Pro tip: 3 ways of automatically creating test scripts on Keithley instruments | Tektronix
MATsolutions' insight:

 

Save yourself time (and headaches) by creating test scripts automatically, and get your setup commands directly from the equipment. 

 



Article Excerpt:

Writing test code can be challenging enough on its own but add poring over the instrument programming manual to extract the right series of commands and you may quickly find yourself with a headache. It would stand to reason that you could save considerable time if your instrument just told you how to program it. The good news is that if you select the right piece of equipment, this is entirely possible.


Working with waveforms in mixed-domain oscilloscopes

Working with waveforms in mixed-domain oscilloscopes
MATsolutions' insight:

 

The Tektronix MDO3000 Series oscilloscope’s internal AFG has a library of 13 permanent waveforms. Shop the series here.

 



Article Excerpt:

Waveform generators generally contain a library of common waveforms, which can be individually accessed and displayed by running a BNC cable to an active analog channel input in an oscilloscope. Most oscilloscopes have, available as an option, an internal arbitrary function generator (AFG), which permits the user to create an endless variety of waveforms and display and save them to internal memory or to an external medium. These internal AFGs also have a selection of pre-made waveforms, although not as extensive as in the stand-alone bench-type waveform generators.

Temporary Wiring: How to plan for test facilities and the outdoors

Temporary Wiring: How to plan for test facilities and the outdoors
MATsolutions' insight:

 

Occasionally, test regimes will require test instruments to be set up outdoors, and research needs to be done in temporary areas. This article will help you make sure your setup is done safely. 

 

 



Article Excerpt:

"This means that if you are prototyping electrical equipment, you can use wire nuts outside of an enclosure to splice in power and you don’t have to worry about NEC compliance. On the other hand, this must not be allowed to become a permanent installation."

Turning Wi-Fi testing sideways: Inside Verizon's Sideways House

Turning Wi-Fi testing sideways: Inside Verizon's Sideways House
MATsolutions' insight:

Take a look inside Verizon's Sideways House used to conduct testing for Fios and eventually, 5G. 



Article Excerpt:

When a company tests how well their residential Wi-Fi access points work, they want to replicate the home environment as closely as possible, right down to building materials and furniture. Often that means renting or purchasing a more-or-less typical suburban home to use as a test house. Some even outfit the house with tracks on which device-equipped test robots can run, to assess device and network performance as a user moves from room to room.
