The PC’s monitor displays the measurements results – but that’s where the Fourier Analyzer dependence on the PC stops. All of the data acquisition, data management, signal processing and other computationally intensive operations are reserved for the Fourier Analyzer’s high-performance measurement and analysis hardware. Built-in analog and digital anti-alias filters automatically track all of the bandwidth settings. A selection of frame sizes allows the user to choose the best trade-off between acquisition time and frequency resolution. When high frequency resolution around a specific signal is needed, the option "zoom" feature can be used. It allows one to focus up to 800 spectral line with a span as small as 10 Hz about the frequency of interest. | The PC’s monitor displays the measurements results – but that’s where the Fourier Analyzer dependence on the PC stops.
