Another useful feature, previously unavailable with receivers of this price class, is a test and measurement
facility, performing measurements on the received signal including frequency accuracy, amplitude modulation
depth, frequency deviation, THD (total harmonic distortion) and SINAD. An audio spectrum analyzer is also
included, making it possible to observe the demodulated spectrum in real-time with a resolution of 5 Hz.
The unique research and education function makes it possible to explore interactive block diagrams of the
software-defined demodulator, for each demodulation mode, and observe demodulation taking place on real-time
signals using two spectrum analyzers and a vector voltmeter.
