SV4401A – 4.4G VNA - 50 kHz to 4.4 GHz
The SV4401A also supports firmware updates, PC software, and replacement parts, making ongoing use, maintenance, and upgrades more practical. If you need more than a basic pocket instrument for occasional SWR checks, and want a handheld VNA that is better suited to serious RF measurement work, the SV4401A fits that role more clearly.
