RF survey in action with the #SP145 ⚡ Using a simple antenna setup in a van, this demo shows just how much spectrum activity is happening all around us, from booming #FMbands to signals stretching out past 4–5 GHz. With the SP145 in #sweptanalysis mode, it’s easy to visualize what’s going on across the spectrum, adjust reference levels when signals are strong, and capture activity from a high vantage point. > t.co/czueacBbPp
