Where can you find an RF designer or manufacturer of wireless ATE devices that can deliver high performance at a reasonable cost for your custom applications? The answer is once again, Vaunix. We routinely handle requests for a special capability or feature that our Lab Brick signal generators, digtal attenuators, phase shifters, and switches do not have as standard features. As an example, pulse modulation [...]

Phase shifters are used in countless applications, with one of the most popular being phased array antennas. These antennas do not require a gimbal to keep the beam stabilized. Without this technology the antenna and/or satellite would have to physically adjust itself in three dimensions to simply stay on target—which can prove to be a difficult task, especially where some applications require [...]

Sifting through the available signal generators on the market to find a reliable, cost-effective option for a test facility can be cumbersome. While it is good to have a basic understanding of the specifications listed on the datasheet, it still does not help with digging through the wide array of options in the marketplace. To make things a bit easier, let’s dive into the differences between [...]

What is a Signal Generator? An RF signal generator is electronic piece of test equipment that generates RF signals over a wide variety of frequencies with high spectral purity, stable frequency, and stable amplitude. RF signal generators are not to be confused with vector signal generators, which generate RF signals but also have complex digital modulation capabilities with formats such as QPSK, [...]

How Scott and Alan Met The founders of Vaunix, Scott Blanchard and Alan Olsen met over 20 years ago while working for Advanced Techcom, Inc. (ATI)—a Massachusetts based design and manufacturer of digital microwave and millimeter-wave radio systems for short and long haul voice, data, and video applications. During their time working at ATI, a number of fortuitous events allowed them to work [...]

In the past, large production environments and sophisticated labs were the dominant influence on the research and development that led to yesterday’s full-featured benchtop equipment market. Today, however, nimble test and verification teams are increasingly looking for more portable and cost efficient solutions devoid of cluttered GPIB cabling and specialized software. Not only has the debugging [...]

High-speed switches like our Lab Brick models are integral parts of many test systems, so I'll explain how easy it is to configure them in this blog. Lab Brick software lets you operate your switch (or switches) in four modes. Manual control mode lets you operate the switch from the computer's display. You just select “Internal” in the Switch Control window and in the Switch Setting [...]

Few instrument set-ups are complete without attenuators, as without them your ability to evaluate the performance of your device under different conditions would be severely limited. Our Lab Brick attenuators combine both the performance and the configurability you need to provide a wide range of measurement flexibility, and setting them up is performed the exact same way as all of our products &ndash [...]

My first blog in this series described the value and capabilities of Lab Brick software and the second described the function of our Lab Brick signal generators, so now let’s look into our Lab Brick phase shifters.   As you can see from the figure to the right, all settings you’ll need to make are available from a single screen. On the right you’ll see a setting for “Frequency [...]

As instruments rather than components like attenuators and phase shifters, signal generators are obviously more complex, and our goal has been to make the Lab Brick LSG and LMS Series instruments easy to use but very capable.   As you can see from the figure below, frequency, frequency and power step size, as well as pulse and sweep modes are all configured in the same screen. The frequency-setting [...]

In ATE systems, an instrument controller handles all the tasks associated with making everything work together. However, when you’re controlling just a few devices to accomplish a measurement task (for example), that’s usually more than you really need. But you do still need a way to control, configure, and run routines using the components, and that’s where the simple yet effective [...]

In a previous blog we suggested that “it doesn't take much imagination to envision a ‘homebrew' test system (built using Vaunix) components”, and we weren't kidding. The fact is that all of our products were created to give engineers, whether they're in design, prototype, or production, a great deal of flexibility. Here's what we mean.   Our signal generators, [...]

Today’s high-end benchtop vector signal generators are a marvel of RF and digital engineering. They’re generally considered the standard by which all others should be judged. While this may be true in terms of their versatility and sheer range of capabilities, it’s possible today to build a low-cost instrument smaller than a paperback book and weighing less than a pound whose core [...]

Today’s signal generators, from portable to bench types, are endowed with an impressive array of features designed to make them useful in every conceivable application. They’re powerful tools -- but they’re also expensive and for many measurement tasks their “feature-rich” capabilities are simply unnecessary and even get in the way. In short, sometimes all you need (or [...]
