Specifications and Features Now Showing in Used-Line Listings

Please Share

You’ve seen our T&M Specifications page, haven’t you? Well, it just got smarter. We added behind-the-scenes instruments that don’t necessarily fit into the T&M Specifications categories, but that do show up under ads in Used-Line listing categories.

Ok, we can hear you saying now: What are they talking about?

So, let’s explain.

Here’s how it usually works.

If you visit our Specs page, you’ll find 31 Test & Measurement Categories in which you can perform two tasks:

  • Check and compare product specs.
  • Find a particular model’s listings on Used-Line.

Let’s choose Signal Generators, for example. You view a table of (currently) 426 models and their specs, such as frequency ranges and output power.

Signal Generators Specs on Used-Line T&M Specs page.

So, let’s pick one. We’ll select the Spanawave (formerly Giga-tronics) 2550B. When we click through we land on a page showing the specifications and a description of the 2550B. (Scroll up to view the 2550B product listings.)

That is the usual case.

Now, what happens if you want to view the specs of an item that we have not showcased on our T&M Specifications page?

What about a resistor, for example?

Resistor, anyone?

A resistor?! You’re right. We do not have a special category for resistors in our T&M Specifications, but we do have the following categories in Used-Line’s listings of resistors ads:

Now, let’s go to Used-Line and search for a Guildline Instruments 9330, a standard resistor whose design meets the need to reduce the typical sources of errors found in older designs – that is:

  • Temperature coefficients
  • Thermal and electrical time constraints
  • Thermal EMF’s
  • Voltage and power coefficients

Scroll to the bottom of the 9330 listing results and what do you see?! A paragraph discussing the  specifications and features of the 9330 based on the manufacturer’s description!

Now you’re not going to find descriptions of every single product that is advertised for sale on Used-Line.

Yet!

But we’re working on it!

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.

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.

Live from Tektronix: The new Real-Time H500/SA2500 Spectrum Master

Please Share

The new Tektronix handheld spectrum analyzers, the H500 and the SA2500, which were recently added to Used-Line.com’s T&M Specifications page, are ruggedized instruments with an interface that has been designed for high quality visibility and easy navigation in the field.Tektronix H500/SA2500

But these usability features do not detract from the analyzer’s performance specifications. With a 10 kHz to 6.2 GHz frequency range, a +20 dBm to -160 dBm reference level range, and 100% POI for transients with 125 µs minimum signal durations (H500), these spectrum analyzers pack a punch that can be found in many desktop analyzers.

However, according to Jim McGillivary, general manager of the Tektronix Source Analyzer Product Line, “…what makes these instruments truly revolutionary is our unique real-time DPX™ live RF spectrum display technology. No other instrument or technology offers such a practical, fast and easy way to discover unknown, randomly occurring digital RF events.”
