Keeping pace with increasingly intelligent machines

Keeping pace with increasingly intelligent machines

A modern automobile has millions of lines of code, which can range in functionality from engine control to navigation to automated seat adjustment. While no off-highway vehicle currently incorporates this many ECUs, National Instruments is quite sure this level of software integration is most certainly on the horizon for agriculture and construction equipment.

Everyone who has used a webpage, phone app, or other consumer software product is aware that errors in software are common and expected. The challenge is that in the consumer space, these errors are typically resolved with a quick reset of the application with relatively little impact to the user (lost data excluded).

However, when this paradigm is applied to an electromechanical system these errors can have catastrophic consequences if they are present when the customer operates the machine.

Will IoT Sensors Lead to Test Headaches?

Will IoT Sensors Lead to Test Headaches?

"As any experienced engineer knows, sensors are the most vulnerable part of a system. Due to their inherent role, sensors are exposed to the nasty real world of moisture, vibration, temperature, and other physical stresses to a lesser or greater extent. Sometimes the exposure is directly due to what is being monitored, but often it is a side effect of monitoring some other parameter. Regardless of the cause, sensors live a much harder life than the electronics on the typical PC board, even if that board is in an automotive environment. 

The problem is that as we add IoT sensors to everything, we'll be seeing more false positives and negatives that will be harder and harder to test and assess. Soon, planning for how to test the veracity and credibility of the many readings and alarm indicators will become a larger part of the project."

MATsolutions' insight:

Have you experienced too much IoT-like sensor information causing false alarms, and subsequent unnecessary shutdowns of the system, or just ignoring of all alarms?

The number and types of sensors are growing significantly. EE Times discusses how this also could result in many unforeseen system-oversight implications.


Simple Transient-Response Measurement Determines Power-Supply Bandwidth

Simple Transient-Response Measurement Determines Power-Supply Bandwidth

It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response—no good reference exists that defines this in simple terms. It seems like a straightforward problem, which should have a simple solution. The higher the bandwidth, the faster the loop responds, and with less voltage deviation.

It's not always that straight forward, however. 


MATsolutions' insight:

Ascertaining the relationship between bandwidth and response in power supplies isn’t easy, but this idea for design presents a measurement approach that helps ease the process.


What Every Engineer Should Know about Oscilloscope Probes: Passive vs Active

What Every Engineer Should Know about Oscilloscope Probes: Passive vs Active

I’ll bet you have quite the stock of random probes on your bench. And, you’ve inevitably reached for a probe and made a measurement without even knowing which probe you were using. I’m guilty, too. Probe selection can seem awfully confusing, so we often resort to this “random selection.”

 

The fact is, probe selection can significantly affect your measurement, so let’s break this down and walk through the one simple thing every engineer should know about oscilloscope probes: what the difference is between passive and active. Use this guide as the first step to better, more accurate measurements.

5G Data Requirements to Amplify the Need for Network Testing

5G Data Requirements to Amplify the Need for Network Testing

A tremendous increase in global mobile data traffic due to the use of video and other high data applications on smartphones is causing network overloads. Wireless network testing is witnessing a resurgence due to the high demand for a better customer experience.

 

Traditional drive test solutions are no longer sufficient to provide a true picture of the quality a customer is experiencing. Thus, there is a need for additional operation support systems (OSS) tools with geo-location, as well as highly effective active and passive monitoring probes.

Top 10 Things to Consider When Selecting a Digitizer/Oscilloscope

Top 10 Things to Consider When Selecting a Digitizer/Oscilloscope

The modern day digital storage oscilloscope is dramatically different from the cathode ray oscilloscope German scientist Karl Ferdinand Braun invented in 1897. Technology advances continue to provide new features that make the oscilloscope more useful to engineers, but one of the most significant transformations of the oscilloscope was its transition into the digital domain, which enabled powerful features such as digital signal processing and waveform analysis. Digital oscilloscopes today include a high-speed, low-resolution (typically 8 bits) analog-to-digital converter (ADC), defined controls and display, and a built-in processor to run software algorithms for common measurements.

Since oscilloscopes are PC-based, you have the advantage of being able to define your instrument functionality in software. As a result, you can use an oscilloscope not only for general measurements, but also for custom measurements, and even as a spectrum analyzer, frequency counter, ultrasonic receiver, or other instrument. With their open architecture and flexible software, oscilloscopes provide several advantages over traditional stand-alone oscilloscopes. When choosing an oscilloscope there are many considerations to keep in mind when selecting the instrument to fit your application.

This paper discusses the top 10 things you should keep in mind if you are considering a new digitizer/oscilloscop

5 Reasons Why Pharmaceutical Companies Should Use Accredited Calibration Labs?

5 Reasons Why Pharmaceutical Companies Should Use Accredited Calibration Labs?

Instruments in pharmaceutical companies should be calibrated so that their performance and results can be trusted. There should be no shred of doubt if the equipment has been calibrated as per the required standards or not. This is why you must use an accredited calibration lab for your equipment calibration. 


Pharmaceutical companies cannot afford to be lenient about calibration or compromise on the quality. Any kind of inaccurate measurement can cause a breach of process, product recall or potential fines from the FDA. Moreover, the user’s life could be put at risk. Even if there is a small variance, you can be subjected to large cost over-runs and a dip in the quality. 


To avoid such issues, you must use calibration service of accredited labs. There will be a massive difference in the accuracy and quality of the service you receive from an accredited lab as compared to a non-accredited lab.Let us look at 5 benefits that accredited calibration labs provide:

Find the Right Analog Signal Generator - National Instruments

Find the Right Analog Signal Generator - National Instruments

Analog output instruments provide static or dynamic multichannel analog output signals. They enable you to create applications such as stimulus-response, power supply control, deterministic control, and sensor/signal simulation. Analog Output Devices offer various output resolutions, channel counts, and other onboard features, so you can replace several kinds of instruments in your system, including stand-alone proportional integral derivative (PID) controllers, low-speed arbitrary waveform generators, and function generators. Basic, DAC-based analog output devices should generally only be used for low-speed waveform and static generation applications.
