A few weeks ago we finished up a four-part blog series about the basics of real time spectrum analysis. In the blog series we discussed the basics of how a spectrum analyzer works, why we need them, and the differences between spectrum analysis and real time spectrum analysis, among other things. Armed with this basic …
This is the fourth and final post in a multi-part blog series, teaching you the essential concepts of spectrum analysis. With the advent of wide bandwidth analog-to-digital converters (ADCs), high-speed memory, fast processors, and efficient fast-fourier transforms (FFTs), tens to hundreds of megahertz of instantaneous bandwidth can be processed as fast as it is received. …
This is the third post in a multi-part blog series, teaching you the essential concepts of spectrum analysis. When attempting to analyze or characterize modern telecommunications systems and devices, a spectrum analyzer’s (SAs) ability to measure power over precise sections of spectrum is invaluable. The quality of transmission, nonlinearities, and phase noise of a communication …
This is the second post in a multi-part blog series, teaching you the essential concepts of spectrum analysis. A measurement on a spectrum analyzer (SA) is taken by configuring, often through software, several key measurement parameters. Many spectrum analyzers have a default setting, along with adjustable center frequency, bandwidth, and power levels. However, not all …
We released Spike v3.0.22 today, featuring the following enhancements and fixes: Enhancements Changed Native/Non-Native RBW selection to Nutall/Flattop, respectively (these terms are more descriptive and useful when making measurements) Added CISPR defined RBW filters (these RBW filters provide the 6dB bandwidth and shape that is desired for EMC/EMI measurements) Increased marker resolution …
This is the first post in a multi-part blog series, teaching you the essential concepts of spectrum analysis. From browsing the internet on your smartphone to surviving the cramped seating arrangement of a modern airliner, RF and microwave electromagnetic (EM) signals enable communication of information for everything from public safety to social media. The devices …
It’s no secret: the wireless world is hot. From the top tech companies in the world to homebrew hackers working in their basement, wireless communications are changing the world in exciting ways. Working with radio frequency is standard fare for many in the electronics world, and there are many tools available to help when developing …
A few years ago, we sent the devices in our 4.4 GHz scalar network analyzer product combo to the editors of QST magazine for a review. They received the USB-SA44B and USB-TG44A in brand-new, just-off-the-manufacturing-line condition, and we were really excited to get some feedback from such veterans in the field. We anxiously waited. And then we waited some …
YouTube user TRXBench recently posted an amazingly thorough and in-depth review of our 4.4 GHz scalar network analyzer. Coming in at just over 2 hours and 15 minutes (wow!), the video goes through couple different processes, covering everything from unboxing and software installation to use and experiments. If you’ve ever been curious as to how …
Okay, so maybe this was technically posted last year, but that was still only a few weeks ago at this point. Microwave Journal Editors Pat Hindle and Gary Lerude present a brief holiday-themed rundown of smaller, low-cost test equipment products that were released during 2015. The VSG25A vector signal generator was first amongst the mentions. …
