Rohde & Schwarz FMA High Precision Modulation Analyzer
The Rohde & Schwarz Modulation Analyzers FMA and FMB provide fast and high-precision analysis of all parameters of a modulated signal. Thanks to their versatility they can also be used as RF counters, power meters, voltmeters, psophometers and distortion meters.
The two modulation analyzers only differ in the frequency range they cover. The FMB operates from 50 kHz to 5.2 GHz, the FMA from 50 kHz to 1360 MHz but can be retrofitted to 5.2 GHz. These frequencies are becoming increasingly important for new radio services and special outside-broadcasting links.
Radiotelephony and calibration of signal generators are further applications of these analyzers. Their unrivalled measuring accuracy warranties reliable values.
The low inherent spurious modulation and the psophometer function using the optional CCIR and CCITT filters facilitate measurements and the development of oscillators, transmitters, transposers and receivers.
