Capturing, extracting and storing narrowband IQ data for later processing enables timely and efficient analysis. As wideband capture of RF information includes noise and non-signal elements, the present invention detects, extracts and stores narrowband IQ signals for later assessment. By transforming a high-volume data stream to a collection of smaller narrowband signals with greatly reduced storage and on-board processing requirements the present invention facilitates the capability to analyze signals of interest in an otherwise denied environment.

Exemplary embodiments dynamically select the LO frequency and mixer mode (i.e., low-side LO injection or high-side LO injection) for upconversion based on the desired RF output frequency in order to mitigate the effects of spurious and LO leakage signals that could violate radiation emission limits, e.g., in the case where the IF signal frequency is smaller than the RF operating band. By dynamically switching the LO frequency and mixer mode as a function of the requested operating RF channel, low-level emissions and spurious signal compliance with restricted bands can be achieved.
