1. A method for recording data from a wireless communication transmission with a receiver, the method comprising:

  • disabling at least a portion of non-essential electronics when the receiver is in a receive mode;

    starting a capture sequence for the receiver in the receive mode;

    receiving the wireless communication transmission during the receive mode;

    identifying an received in-phase (I) signal and a received quadrature-phase (Q) signal from the received wireless communication transmission during the receive mode, wherein the received in-phase (I) signal and the received quadrature phase (Q) signal correspond to a complex base-band signal;

    digitizing the complex base-band signal from a captured transmission during the receive mode, wherein the digitized complex base-band signal comprises a digitized in-phase (I) signal and a digitized quadrature phase (Q) signal; and

    storing the digitized complex base-band signal in a buffer without further processing such that the effects of noise in the digitized complex base-band signal are minimized by disabling the at least a portion of the non-essential electronics while the digitized complex base-band signal is received.
