The R&S FPH-K7 option converts the R&S Spectrum Rider FPH into an analog modulation analyzer to measure the quality of amplitude or frequency-modulated signals. The analog modulation display shows the waveform as well as measurement parameters such as carrier power, carrier offset, modulation index (depth) for AM signals, frequency deviation for FM signals, SINAD, THD, etc. The modulation summary display provides user-definable limits for each measurement.
The Analog Demodulation measurement analyzes the AM or FM modulated signals and calculates the analog modulation parameters using the measurement results. Note that the measurement works properly only if you apply an amplitude or frequency modulated signal.
This firmware option provides the necessary measurement functions to analyze amplitude and frequency modulated signals.
The digital signal processing in the R&S Spectrum Rider is used for demodulating amplitude and frequency modulated signals. By sampling (digitization) already at the IF and digital down-conversion to the baseband (I/Q), the demodulator achieves maximum accuracy and temperature stability. There is no evidence of typical errors of an analog down-conversion and demodulation like AM to FM conversion and vice versa, deviation error, frequency response or frequency drift at DC coupling.
