5 Go-To Network Analyzers, Refurbished, Reliable and Up to 70% Less than New

Engineers responsible for testing network parameters, and especially those shopping for new network analyzers, may experience sticker shock. Just as new car buyers see the next year’s models released, new network analyzers with new features and minor style changes appear almost constantly. Before taking a pencil to the RFP, though, cost-conscious engineers (like savvy car shoppers) should take a look at used inventory.

Of course, the reliability of used equipment is always a concern, as – just like cars – some models perform like new for many years, and others don’t hold up as well. That’s why Measurement Assurance Technology offers used network analyzers for sale only after they’re fully refurbished and certified for reliability.   (By the way, to answer a question we’re often asked about buying used network analyzers: yes, we stand behind the products we sell, and we also offer calibration and repair services, just in case.)

We’re not saying used testing equipment is always the best choice – sometimes, you need a particular new feature to manage all of your network’s parameters. However, most of our customers find they can often get the accuracy, range, resolution and output they need with used equipment, and even get most of the bells and whistles they want, for a fraction of the price of buying new. As you compare network analyzers, note some of the used models below and compare their feature sets and  price points.
