Wideband Scanner

The Wideband Scanner (WBS) provides detailed real-time spectrum monitoring measurements by directing a tuner to sweep frequencies typically from 2 MHz to 6 GHz and displaying spans typically from 20 MHz -250 MHz. The wideband IF composite signal is digitized by the ADC and passed to the PC where digital signal processing converts it to frequency domain points.
