Abstract
A signal analyzer comprises: a first tuner configured to tune to a first frequency band and to output first tuner data; a memory device configured to store the first tuner data; a spectrum calculator configured to calculate a series of spectra for the first tuner data; a processor configured to determine a presence of a transmission of interest within the first tuner data based on the series of spectra; a second tuner configured to receive the first tuner data stored in the memory device and to tune to a second frequency band including the transmission of interest. The second tuner outputs second tuner data in response to the stored first tuner data. The signal analyzer also comprises a transmission start time detector configured to receive the second tuner data and to determine a start time for the transmission of interest from the second tuner data.
