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."

 


Measure phase difference with an oscilloscope

Measure phase difference with an oscilloscope
MATsolutions' insight:

This article provides insight into some different methods to measure phase with an oscilloscope. Do you have a favorite one? 

 



Article Excerpt:

"All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal's phase change when it passed through a network. Fortunately, you can also measure phase with an oscilloscope using several methods."

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.

4½ Practical Uses for a Diode

4½ Practical Uses for a Diode
MATsolutions' insight:

 

Diodes are non-linear and passive devices. Learn more about them in this article and see 4½ practical uses for them.

The ubiquitous diode—though you likely have a good understanding of this device, this primer of sorts acts as a quick-read guide, highlighting many of the essentials you need to know.
 


Not All Emulators Are Created Equal

Not All Emulators Are Created Equal
MATsolutions' insight:

 

Hardware-emulation adoption has become a mandatory verification tool in Silicon Valley. Right now, there are three different hardware-emulation technologies, architectures, and implementations. Do you know what they are? 

 



Article Excerpt:

Speed, throughput, and latency are the key parameters in determining hardware-emulation performance.
 


EMI emissions testing: peak, quasi-peak, and average measurements

EMI emissions testing: peak, quasi-peak, and average measurements
MATsolutions' insight:

 

For EMI testing, it is important to have a spectrum analyzer that has the right software to support the different types of testing.  View our spectrum analyzers here: http://srenew.al/191829

 



Article Excerpt:

EMI emissions testing is critical to bringing a product to market. Most electrical and electronic products require regulatory compliance testing, which must be performed in an approved test lab. Such testing can be expensive, especially if the product fails. A failed test can result in lost time to market and cost overruns. 

To minimize unwanted trips to the test lab prior to compliance tests, you can measure EMI emissions from your product. Not only will this increase your chances of passing emission compliance testing the first time, it can help you identify potential issues early on and reduce the need for last-minute product redesigns. There are several measurements you can do using a spectrum analyzer or EMI receiver.

 


5G Will Take Some Rethinking to Scale

5G Will Take Some Rethinking to Scale
MATsolutions' insight:

 

There are some processes that still need to be considered for 5G to come to life. This article explains the discussions from the  5G Summit at the 2018 International Microwave Symposium (IMS). 

 



Article Excerpt:

Before we see 5G networks and handsets, semiconductor fabs will need to change the way that they process wafers, test engineers will have to figure out how to test, and handset designers will have to figure out how to track steered beams as people move. On top of these and other problems, wireless products will have to sell for prices close to current levels. These were the takeaways from the 5G Summit at the 2018 International Microwave Symposium (IMS). 

 


DMM 101: Handheld vs. bench digital multimeters | Tektronix

DMM 101: Handheld vs. bench digital multimeters | Tektronix
MATsolutions' insight:

 

Handhelds and bench digital multimeters both offer different sets of features and capabilities. Take a look at what areas these two sizes perform the best. Which one do you use?  #testandmeasurement

 



Article Excerpt:

By Robert Green
More than perhaps any other instrument category, digital multimeters or DMMs come in a wide range of shapes and sizes. DMMs intended for use in the field emphasize portability and battery operation so service technicians and maintenance personnel can quickly and easily make basic voltage, current and resistance measurements as they go from location to location. For these applications, resolution, accuracy, measurement speed or connection to a computer are less important than battery life, durability and size.


Will 5G be reliable?

Will 5G be reliable?
MATsolutions' insight:

 

The deployment of 5G will likely be longer than LTE because the standard has so many variations and configurations. See what the deployment will look like and what will need to be done to ensure 5G will be reliable.

 

 



Article Excerpt:

In May of this year, I attended an Emerging Technologies Workshop as part of the IEEE ComSoc International Communications Quality and Reliability Conference. During this workshop, I had the opportunity to present some of National Instruments' work in the 5G space, and to learn how others view 5G’s impact. In particular, I was curious to hear more about reliability as a key performance objective of 5G and the specific use cases targeted by the 3GPP. 

 


Making Power Supply Transient Recovery Time Measurements with Digital Multimeters | Tektronix

Making Power Supply Transient Recovery Time Measurements with Digital Multimeters | Tektronix
MATsolutions' insight:

 

Transient recovery time is important to measure to make sure you are not causing the equipment to underperform. 

 

 

This post provides insight on how to measure transient recovery time by walking through the method using the LM25088MH-1EVL evaluation board from Texas Instruments. 



Article Excerpt:

By Josh Brown
Transient recovery time, simply put, is duration of time needed for a power supply to return to its set level after a load is applied. Those of us who do not design power supplies have a tendency to take this for granted, applying whatever loading circuitry we are working on until, perhaps, the supply performance degrades to the point it impacts our own work. Power supplies are a little like people, if you ask more from them than they are capable of, they won’t perform like you might expect.
