Abstract: A method of detecting a trigger event includes receiving an input signal for analysis. The received input signal is used to generate first data corresponding to sequential sets of spectral output data sets, at least some of the spectral output data sets corresponding to sample points in time acquired from the input signal as the input signal changes with time. At least part of the first data is then compared with second data, the second data corresponding to a predetermined sequential set of signature spectral data sets corresponding to a time-varying spectrum associated with a trigger event. A trigger signal is then generated in response to a change in a state of match between the at least part of first and second data.

Abstract: A method of detecting a trigger event comprises receiving an input signal for analysis. The received input signal is used to generating first data corresponding to energy of a frequency content of the input signal as the input signal changes with time. At least part of the first data is then compared with second data, the second data corresponding to a predetermined time-varying spectrum indicative of the trigger event. A trigger signal is then generated in response to a change in a state of match between the at least part of first and the second data.

Abstract: A wireless data communications link connects a wireless device to a test station. The test station transmits command and control parameters to the wireless device using the wireless data communications link. The command and control parameters place the wireless device in a test mode and test the quality and operations of a radio frequency (RF) link established between the wireless device and the test station. The wireless data communications link is also used to transmit test and control parameters from the wireless device to the test station.

Abstract: Using component-level test data to reduce system test. By modeling a system, sensitivity analysis reveals critical components and parameters of those components required to meet system performance parameters. Critical components are tested for these parameters, and these measurements associated with the components. Systems may be assembled which are modeled to meet the system performance parameters based on the model and the measured parameters. Systems may be assembled and calibration coefficients derived and applied from the model and the measured parameters.
