This video provides an overview of the Arinst SSA spectrum analyzer software. It covers the main functions and capabilities of the software. All functions and the software version were reviewed at the time of filming. We are actively improving our analyzer. The device's website is available at http://arinst.ru. For radio amateurs and, in particular, active visitors to the website http://vrtp.ru, we offer a special discount on the device. We are also happy to support educational institutions, non-profit organizations, and other good people in any way we can. Our goal is to make frequency domain measurements accessible to everyone.
