According to Used-Line Research US DOMINATES USED TEST EQUIPMENT MARKET AT 90%! Click To Tweet

What’s behind this astronomical growth and what does it mean for the rest of the world?

As we come to the close of a successful 2015 sales year, we at Used-Line want to share some of our market observations and projections with you, our valued customers.

Used Test Equipment Market Snapshot.

A simple look at the Used-Line Dealers Directory shows North America as the most dominant of the 5 major global markets today by far, with over 70% of our dealers embedded and handling 92% of the products listed.

Used-Line Dealers Directory shows - 70% of North American dealers handling 92% of the products listed Click To Tweet

Europe, handling 6.2% of products, is a very distant second, followed by Asia, Oceania and the rest of the world.

Why is the US Market Growing?

America is experiencing a period of economic growth. The Bureau of Economic Analysis estimates the real gross domestic product (GDP) for 2015 increased at an annual rate of 2.1 percent in 2015 Q3. Employment was up, as well as personal income (up 0.9%) and market optimism translated into higher buying power.

A $4.13 Billion Growth Market

MarketsandMarkets consulting predicts the automated test equipment market will reach $4.13 Billion by 2020, fueled by an increased demand for consumer electronics, more complex designs and a growing need for more effective testing.

But even with the US occupying such a big chunk of the market, other regions are still dealing with a potential market of close to half a billion dollars.

Semiconductors For ADAS

Please Share

Please excuse my ignorance.

When I came across the acronym, ADAS, Advanced Driver Assistance Systems, what popped into my mind was some sort of software or hardware driver – for helping a piece of equipment work inside an application.
However, the indicated ADAS driver in fact sits behind the wheel of a vehicle, typically, a car.
The scope of ADAS is infinite: From an audio beep that prevents you from knocking down your neighbor’s fence while reversing – to automated driverless systems.
The engineering possibilities are limitless as well: cameras, controls, software & hardware drivers, sensors, meters, and more. The designs are not confined to safe driving –  entertainment systems and improvements in driver “usability” are driving development in parallel with vehicle safety features.
The idea behind automatic driving is not new. Assisted driving mechanisms in today’s vehicles are no longer considered “extras”.

Without differentiating between well-known consumer “beeps & whistles” that constitute vehicle extras, and advanced vehicle automation safety design, let’s take a look at some of the driver applications in which semiconductors are embedded.

Handheld Spectrum Analyzer Competes with Benchtops

Please Share

Frequency coverage from the Anritsu MS2720T gets as good as 9 kHz to 43 GHz in model MS2720T-0743, the high end of this series of spectrum analyzers, which starts at its lower end (in terms of frequency) with a model that boasts a continuous frequency range of 9 kHz to 9 GHz. Not too shabby. Launched in December, 2012, this almost two-years-on-the-market handheld could well compete with today’s benchtop analyzers (without external mixers) in the frequency specification department.

Let’s take a look at just a few of the other specs associated with this instrument:

  • Resolution Bandwidth from 1 Hz to 10 MHz
  • Sweep mode speeds: Allow a resolution bandwidth of 30 kHz to 10 MHz with almost no impact on sweep speed
  • Dynamic range is >106 dB in 1 Hz bandwidth at 2.4 GHz
  • DANL is -160 dBm in 1 Hz bandwidth at 1 GHz (preamp on)
  • Phase noise is -104 dBc/Hz at 10 kHz offset at 1 GHz
  • Option of tracking generators from 100 kHz to 20 GHz (full-band)

Read more in the Used-Line T&M Specs pages as well as in the Related Articles below. Do check out the many capabilities available as options for the MS2720T. Not only all the signal analysis packages that a wireless engineer may need for the various data rates of carriers, but a vast selection of analyzers, such as power meter, channel scanner, GPS Receiver, and Interference Analyzer are available as options.

Used Anritsu MS2720T | used-line.comThe Spectrum Master™ MS2720T series provides field technicians and engineers with performance that rivals a benchtop spectrum analyzer. The MS2720T features a touchscreen, full-band tracking generators to 20 GHz, and best-in-class performance for dynamic range, DANL, phase noise, and sweep speed, providing unprecedented levels of spectrum monitoring, hidden signal detection, RF/microwave measurements, and testing of microwave backhauls and cellular signals.

Anritsu suggests that this spectrum analyzer, at 8 pounds “fully loaded” is light enough to take up a tower. Well, you’re not going to get me up any tower, thank you very much, with or without a handheld spectrum analyzer.

CN Tower, Toronto, Canada

I do have quite a bit of trouble picturing an RF engineer making his way up the CN Tower, for example, with a benchtop instrument, so there must be some brave engineers who scale the heights – with their handhelds!

If it was I who had the responsibility of handling this instrument, I would be very much inclined to avail myself of the Anritsu Remote Access Tool, which lets the user sit in the comfort of his lab or office while controlling the spectrum analyzer over a LAN connection, and analyze data with the Anritsu Master Software Tools – in-between his sips of coffee.

But then some folks are made for reaching for the sky, and others are not.

Chickens and the Unbroken Chain of Calibration

Please Share

A recent discussion in the LinkedIn group, Metrology & Test Measurement, on the “unbroken chain of calibration” has driven me to hone in on my personal understanding of measurement uncertainty. I am ashamed to say that I know virtually nothing (0 ±0.0031415929) about calibration despite having worked as an electronics technician in the ’90’s. My excuse is that ISO 9xxx only hit the repair floor in the ’90’s. (Well, that’s why it was called ISO 9000.)  But the National Bureau of Standards (NBS), which predates the National Institute of Standards and Technology (N.I.S.T.) by 87 years, has been around since 1901.

logo of National Institute of Standards and Te...

Logo of National Institute of Standards and Technology (Photo credit: Wikipedia)

And the NBS was predated by the International Bureau of Weight and Measures (BIPM in French). In any case, I’m not quite sure how to connect ISO 9xxx with calibration. It must come into it somewhere. All I remember was what kind of shoes to wear and grounding rules. I guess you could say that my uncertainty around these topics is not measurable or traceable!

How do we arrive at an unbroken chain when it comes to metrology? Let’s go to the start of the chain. We will use N.I.S.T. for discussion purposes but really it applies to any of the international organizations that set standards for metrology.

  1. We start with a reference point. This is a universally known measurement value of a particular measurable event. For example, the melting point of ice. (N.I.S.T uses a thermometer as an example on their website.)
  2. This reference is used as a standard by N.I.S.T. I assume that means that a correctly calibrated thermometer will measure – well, I’m not sure exactly what it will measure. It is close to 0 degrees Centigrade. There are various factors that can determine the temperature, such as atmospheric pressure and the purity of the actual water that the ice is composed of. The point is – a standard is set that will be used to begin the chain. This standard is the reference that all other measurements down the chain are going to be traced back to.
  3. Going down the chain, we compare the measurements of the next instrument to be checked against the N.I.S.T. measurement , then document the differences in the results. Depending on the conditions of the measurement, we can make the necessary adjustments needed to arrive at the most accurate measurement but can never be absolutely certain of a true value. Like much of life, we do our best. The “best” is a range of values that approximates the value of the N.I.S.T standard. This range of values is the range of uncertainty. You know that somewhere in this range, lies the true value and if you calibrate an instrument to show results within this range, you should be able to certify your instrument as calibrated according to the standard. If along the way, you lose the reference, your instrument cannot be considered to be calibrated according to the N.I.S.T. standard.

I know! This is a rather crude, simplistic explanation of the process. I “did my best”!

I got further confused after my visit to the supermarket today. They had fresh whole chickens on sale with a limit of 6 Kg per customer. For the customer’s convenience, a scale was placed near the chickens, allowing the customer to verify the total weight of his selection. The trick was to see whether you could get four chickens for 6 Kg, despite the average weight of 1.55 Kg per chicken. You do the math now. It seemed a shame to buy only three chickens and thus not take full advantage of this special sale. Four chickens were over 6 Kg and three were under by quite a bit.

Well, I came pretty close. I managed to find two smaller looking birds and my total weight on the scale (when last was it calibrated, I wonder?) was 6.14 Kg. I went over to the poultry supervisor and told him that I was a little over the maximum weight allowed, and with a smile on his face, he said, “That’s fine.”

<!–Here’s the moral of my little story–>: The more accurate our measurements are, the more honest we can be in our relationships with customers, clients, and other businesses. However, sometimes in life a little uncertainty goes a long way when it comes to give-and-take with others. <!–End of moralizing–>

Two More Used-Line Usability Gems + One Tip

Please Share

Do you remember my recent post (December, 2013), Used-Line Usability Gems? Where I ‘fessed up that I work for Used-Line.com? And I did say that we have more gems, right? Well, here are three more that our smart web people have developed..

    • Search suggestions include Manufacturers’ names. Let’s say you’re searching for a Leeds and Northrup 4210, 1 ohm resistance standard. You enter the model number, 4210, in the Find Category or Model# box on the top right side of any page on the Used-Line website. The results show that there is a significant number of model 4210’s on Used-LIne. You probably don’t need the Fluke DC 4210 power supply. The Boonton 4210 watt-meter may be useful, but that’s not really what you’re looking for. But wait, there it is! 4210 – Leeds & Northrup is one of the search suggestions that came up.
      MFR shown in search results

      MFR shown in Used-Line search results

      With the inclusion of the manufacturer’s name in your search results, you can quickly find exactly what you were searching for.

    • Ordering directly from the dealer: Some of our dealers have taken advantage of our new Directly From Dealer button. When a buyer opens an ad listed by a dealer using this functionality, he is given the option to purchase directly from the dealer without filling out any forms on Used-Line – thus reducing the number of steps required to complete his transaction. The buyer simply clicks on a thumbnail image that takes him to the specific listing on the dealer’s website. (Click the image below to view this actual ad on Used-LIne.)
Order directly from dealer.

    • Moving up the ranks in Used-Line search results: And here is our tip for the week. It is a tip for promoting your ads on Used-Line. I’m sure you’ve noticed the featured ads with photos, in a row of four mini-banners at the top of a category’s listings page. Featured Items is a special upgrade that you can purchase from Used-Line. (See the page on becoming a member.) What you may not realize about Featured Items is that the mini-banner at the top of the page is not the only benefit you get from this upgrade. You also get to send your ad uprank (I made that word up) in the list of search results (possibly to the top!) when users search for the item you wish to sell. For details on how this works, view the Used-Line video on Featured Items.

Three Ways to View Power Analyzers on Used-Line.com

Please Share

Do you know that there are at least three ways (maybe there are more) to view Power Analyzers on Used-LIne.com? Of course, the same applies to many of the other categories on Used-LIne. But today we are going to focus on just one instrument category – power analyzers – for illustrative purposes.

These three paths all serve different purposes. Used-Line has so much to offers its visitors!

1. View Power Analyzer Listings

Let’s talk about listings first because this is why a potential buyer of a power analyzer will visit Used-Line.com.

How do you find power analyzer listings on Used-LIne?
Well, I could send you the Used-Line Help manual. No. Let’s be honest. Which of our users really need help finding equipment listings on our website?

You probably fit into one of the following four user profiles:

  1. You are a frequent visitor to Used-Line and have been for years, and could probably give a class on how to navigate our website.
  2. You’ve been keeping up with our blog (you have, haven’t you?), and have learned all the tips and tricks for browsing equipment on Used-LIne.
  3. This is your first visit to the Used-Line website. You are in the market for a power analyzer and your favorite search engine brought you here.
  4. You have no interest in power analyzers or in test equipment in general. You simply enjoy reading this blog!

Profile 1: You know what you’re doing.
Profile 2: You’ve learned what to do.
Profile 3: Used-Line developers have made searching on Used-LIne such a cinch, there is no need for instruction.
Profile 4: Keep on reading!

So, no instructions needed – only a link: Used-Line Power Analyzer Ads.

Now that you’ve seen the listings, how about some descriptions of the various power analyzers that are listed?

Which takes us to Used-Line’s specifications pages for test and measurement equipment.

2. View Power Analyzer Specifications

If you followed the link to the power analyzer listings on Used-Line, you will have noted that there are 871 listings (as of today’s date)! Of course, you may have already decided which model you want, or you are a dealer looking for a specific manufacturer’s analyzer for one of your customers. But, what if you’d like to know a little more about a particular model? Or you want to check specs and features of a number of models before making your purchasing decision? What kind of power analyzer operation modes are essential to your work environment? Is harmonics measurement a must-have feature?

In other words, you would like to learn more about what types of analyzers are available and drill down into some specific characteristics about the various models in the market.

Here’s what you can do:

    1. Visit Used-Line’s T&M Specifications pages.
    2. Choose Power Analyzers.
    3. Browse the analyzers if you wish, then select one that you are interested in, for example, the discontinued Fluke 435. And here it is.
      Used Fluke 435 | used-line.comFind your used Fluke 435 Power Analyzer at used-line.com, the Online Marketplace for used Test and Measurement equipment.

      Embedly Powered

And here’s the best part! After studying the specs and features of the Fluke 435, you may decide this is just what you have been looking for. Scroll up the very page you landed on to view the Fluke 435 features description and you will find all the current Fluke 435 listings on Used-Line.

3. View the Power Analyzer Glossary

Yes, Used-Line actually provides a glossary of terms. Most, but not all the terms, are key specifications organized by instrument. Figuring that most of our users are familiar with the specs of the instruments they are interested in, we’ve hidden the glossary in the small fine print that can be found at the bottom of each page. Go ahead and see if you can find it. You just never know when you may need to look up a spec description while browsing our listings. Let our glossary get you started on your search for specification definitions. In case you don’t have a magnifying glass on hand, here’s the link. Of course, you want the Power Analyzer glossary, so that in case you were losing sleep wondering what Total Interharmonic Distortion really is, click below to find your answer.

Power Analyzer Glossary Terms | used-line.comA power analyzer, also known as an energy analyzer, is an electronic device that measures single-phase or three-phase electrical energy as it flows through a circuit or is distributed through electronic or motorized equipment. Electrical measurements commonly taken with a power analyzer include volts, amps, watts, frequency, reactive power hours, maximum power, phase angles and harmonic distortion.
