Filters Counter Address DATA and control bus Figure 3 2 Measured data processing The UDC converts the digital IF signal to base band and filters the base band signals using low pass filters with programmable bandwidth In addition it delivers the AM or FM demodulated audio signal The ASIC also detects the envelope of the filtered and combined base band signal and calculates its logarithm It contains also the video filter and the different detectors In addition it is responsible for the sweep control of the R amp S FSH 3 1 8 Resolution bandwidths RBW The resolution bandwidths are implemented in the R amp S FSH through digital processing in the UDC ASIC Digital Down Converter The RBW can be selected from within the range 100 Hz to 3 MHz in 1 3 10 unit increments The UDC first mixes its input IF to the baseband using a NCO Numeric Controlled Oscillator and then filters the resulting IQ signals via a combination of HDF High Decimation Filter and a FIR filter Finite Impulse Response stages At the end of the UDC processing chain the IQ signal is split into magnitude and phase For AF demodulation the amplitude information is used In the case of FM the phase information is used and fed to the headphone connector In the analyzer mode the signal at the position of the marker can be demodulated In this case the R amp S FSH stops the sweep for a selectable period of time and demodulates the input signal The volume can be
