Abstract:
A method for real-time analysis of a system, comprising the steps of:a. providing a means for controlling, the means for controlling storable and executable on a computer means having a memory storage device;b. generating at least one phase transmit signal and at least one phase-shifted transmit signal by a means for transmitting in communication with the means for controlling, the means for transmitting communicating each phase transmit signal to the system, the means for transmitting having a first means for digital synthesizing in communication with the means for controlling, a second means for digital synthesizing in communication with the means for controlling and a multi-channel means for multiplexing in communication with the first means for digital synthesizing and the system;c. obtaining at least one response signal from the system by a means for receiving, each response signal corresponding to each phase transmit signal, the means for receiving in communication with the means for controlling and the system;d. mixing the phase transmit signal and the phase-shifted transmit signal with each corresponding response signal to produce a mixed signal;e. transmitting the mixed signal to the means for controlling; andf. allowing the means for controlling to execute a stepped frequency sweep of the mixed signal over a predetermined frequency range, the means for controlling generating frequency information from each mixed signal, phase information from each mixed signal and time domain information from each mixed signal.
