ADC
The ADCs (analog-to-digital converters) convert analog signals fed to the receiver and
converted into IF signals (R

) into digital signals. One ADC is
available for each signal and the conversion takes place simultaneously.
Digital Filter
The digital filter performs a discrete Fourier transformation (DFT) and picks up IF signals.
Each IF signal is then converted into a complex number that has a real part and an
imaginary part. The IF bandwidth of the analyzer is equivalent to the bandwidth of the
DFT filter. The IF bandwidth can be set in the range of 10 Hz ~ 100 kHz.
