Frequency data, such as FFT spectrum data captured from a narrowband receiver such as an IEEE 802.11 Wi-Fi receiver are combined to display representative real-time FFT, average FFT, and FFT duty cycle data of a wideband spectrum. Data is captured from narrow band radios such as access points, station monitors, or client devices on a wireless network. A wideband spectrum may be aggregated from data captured from one or from multiple devices. Data may be stored for later analysis and display. ## Claims ### Claim 1 A non-transitory machine readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of a set of operations comprising: accumulating spectral data from a radio scanning a plurality of channels;
