Abstract: Methods and systems for modulating a signal are described. A phase-modulated signal that includes a sequence of contiguous one-cycle sinusoidal waveforms having a frequency above 50 MHz is generated. The phases of the one-cycle sinusoidal waveforms correspond to symbols of a message signal. A bandwidth of the phase-modulated signal is reduced using a bandpass filter centered at the frequency of the contiguous one-cycle sinusoidal waveforms. The phase-modulated signal is wirelessly transmitted.

Abstract: A method of calibrating automatic test equipment (ATE) having transmission paths that transport signals includes obtaining amplitude gains of the signals across the transmission paths, obtaining phase delays of the signals across the transmission paths, obtaining magnitude and phase offsets associated with the signals based on the amplitude gains and the phase delays, and calibrating the ATE using the magnitude and phase offsets.

Abstract: A method and system for measuring a device under test includes connecting a first test instrument and a second test instrument to a programmable logic device. The programmable logic device is configured to comply with interface specifications of the first test instrument. The second test instrument has interface specifications that are different from the interface specifications of the first test instrument. The programmable logic device is configured to comply with the interface specifications of the second test instrument.

Abstract: A pre-selected fish grazing system to enhance harvesting of such pre-selected fish from a body of water. The fish grazing system includes at least one conductor unit attached to a body of a pre-selected fish for acting as a guide for other preselected fish present in such body of water. A control device is disposed in such conductor unit for controlling a path the pre-selected fish is to follow. A predetermined number of buoys are strategically located in such body of water for sending communication signals to such at least one conductor unit attached to the body of the pre-selected fish to direct such pre-selected fish having such conductor unit attached thereto a desired location.

Abstract: Automatic test equipment (ATE) includes interleaved analog-to-digital (A2D) converters to produce digital signals, where the digital signals are used to produce an output signal, the output signal having spurs, a look-up table (LUT) to store correction values, where the correction values are for reducing the spurs in the output signal, and circuitry to apply the correction values to the output signal.
