Abstract
A time-interleaved RF triggering method and system on a test and measurement instrument includes an acquisition component that samples a waveform, which is converted into an amplitude, phase, frequency, in-phase (I), and quadrature (Q) waveform, any of which can be used for triggering an RF digital trigger, including triggering that uses demodulation and/or decoding of the down-converted complex IQ data samples for a given protocol. Aliasing caused by subsampled data in each of the interleaved acquisition components is cancelled out using a fractional time-shift filter.
