Rohde and Schwarz FPC-K7 – Modulation Analysis Option for FPC Spectrum Analyzers

The R&S FPC-K7 software option converts the R&S FPC into a modulation analyzer for measuring the modulation quality of amplitude or frequency-modulated signals.

The analog demodulation display shows the waveform as well as a summary of measurement parameters such as carrier power, carrier offset, modulation index (depth) for AM signals, frequency deviation for FM signals, SINAD and THD. The modulation summary display provides user-definable limits for each measurement. Demodulated audio is supported via the built-in speaker or the head-phone jack.

Basic digital modulation formats are used with many applications, e.g. near-field communications. The R&S FPC supports both ASK and FSK analysis. The digital modulation displays include trace, eye diagram, modulation error and symbol analysis. Specialized configuration presets for Bluetooth Low Energy (Bluetooth LE) and tire pressure monitoring systems (TPMS) are available, too.

The R&S FPC-K7 option lets users easily verify the quality of the basic modulated signals.
