Patent number: 8415941Abstract: A method for identifying and reducing spurious frequency components is provided. A method in accordance with at least one embodiment of the present disclosure may include generating a digital sinusoidal waveform at a direct digital synthesizer (DDS) and receiving the digital sinusoidal waveform at an audio digital-to-analog converter. The method may further include converting the digital sinusoidal waveform to an analog sinusoidal waveform containing spurious frequency components, combining the analog sinusoidal waveform with an analog distortion correction waveform to generate a composite output waveform and receiving the composite output waveform at notch filter circuitry. The method may also include filtering the composite output waveform to generate a filtered composite output waveform and amplifying a difference between the filtered composite output waveform and a signal from a circuit-under-test (CUT) to generate an amplified analog signal.Type: GrantFiled: April 20, 2011Date of Patent: April 9, 2013Assignee: LTX-Credence CorporationInventors: Solomon Max, Christopher Joel Hannaford, R.

Patent number: 7957924Abstract: A method, circuit, and computer program product for receiving a first intermediate signal that is at least partially based upon a first reference signal. A second intermediate signal is received that is a time-shifted version of the first intermediate signal. An output signal is generated that is based upon the difference between the first intermediate signal and the second intermediate signal. An anticipated differential change in the output signal is determined, the anticipated differential change to occur based upon a transition in the first reference signal. A realized differential change in the output signal is measured, the realized differential change occurring based upon a transition in the first reference signal. The realized differential change in the output signal is compared to the anticipated differential change in the output signal to determine a nonlinearity indicator.Type: GrantFiled: May 9, 2008Date of Patent: June 7, 2011Assignee: LTX-Credence CorporationInventors: Richard Liggiero, III, Alan J.
