TSP #121 – Rohde & Schwarz FPC1500 5kHz – 3GHz Spectrum Analyzer Review, Teardown & Experiments

In this episode Shahriar reviews the newly released FPC1500 Spectrum Analyzer from Rohde & Schwarz. With this addition Rohde & Schwarz continues to aggressively target the entry level market across a wide range of instruments. These units are packed with competitive features some of which are not found in other instruments in the same class. The FPC1500 employs a 10.1″ WXGA LCD screes and a built-in tracking generator with a fully independent synthesizer which allows for offset tracking as well as a built-in VSWR bridge capable of making vector S11 measurements. These features combined with built-in WiFi, wide range of measurement capabilities and digital demodulation of ASK/FSK signals provides a competitive product.
