| There are numerous demodulation modes, continuously variable IF bandwidth 1
Hz to 15 kHz (in 1 Hz increments), a 20 kHz wide real-time spectrum analyzer
with 16 Hz resolution, noise blanker and notch filter. There is also an
integrated recorder, making it possible to instantly record and playback the
received signal.
Apart from audio recording and playback, the receiver can also record an
entire 20 kHz wide IF spectrum, making it possible to thoroughly analyze the
received signal, and "re-receive" the same signal again and again with different
IF filter bandwidths, notch filter, noise blanking or demodulator settings, to
arrive at the best possible reception of weak or interference-prone
transmissions.
In addition to the real-time narrow-band spectrum analyzer, there is also a
wide-band spectrum analyzer which
contains additional professional instrumentation facilities: the ability to
display minimum and maximum spectrum sweeps, search for peaks, average spectra,
save and print spectra, marker mode, etc.
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.
