Patent number: 8965727Abstract: An automated phase noise test measurement system includes a software controlled phase shifter to maintain quadrature so that a carrier may be removed from a signal provided by UUT. In this fashion, the UUT's phase noise may be measured. Based upon the UUT's measured phase noise, controllable variable(s) within the UUT are tuned so as to minimize the measured phase noise.Type: GrantFiled: May 20, 2005Date of Patent: February 24, 2015Assignee: OmniPhase Research Laboratories, Inc.Inventor: Eugene Rzyski

Patent number: 6647445Abstract: The present invention provides for the compression of digital and analog data for storage and transmission. Analog data in the form of an analog signal is converted into a digital signal by an analog-to-digital converter. The digital signal is then converted into an analog signal having an alternating frequency by a first converter processor and an alternating frequency generator according to a predetermined conversion table. To reproduce the original analog signal, the analog signal having an alternating frequency is first converted back into a digital signal by an alternating frequency measurement means connected to a second converter processor, also in accordance with the predetermined conversion table. The digital signal is then converted to the original analog signal by a digital-to-analog converter.Type: GrantFiled: April 23, 2002Date of Patent: November 11, 2003Inventor: Eugene Rzyski

Patent number: 6496064Abstract: A cancellation circuit is provided for canceling undesirable intermodulation (IM) products in electrical circuitry. The IM cancellation circuit includes a stepping spectrum analyzer which recognizes and measures the frequencies and amplitudes of different signal components of an RF signal across a desired frequency band. This information is forwarded to a processor which contains look-up tables or the like which provides information relating to the frequencies and/or amplitudes of signal components which are intended to reside in the RF signal. By comparison of the look-up tables to the frequencies and amplitudes measured and recognized by the sweeping spectrum analyzer, the processor of the cancellation circuit is able to determine whether the signal components in the RF signal are intended “information” carrying signals or unintended IM products.Type: GrantFiled: June 21, 2001Date of Patent: December 17, 2002Inventor: Eugene Rzyski

Patent number: 6393372Abstract: A noise measurement test system is provided for making phase noise measurements of a unit under test (UUT). The noise measurement test system comprises a variable amplifier, a variable low noise source, a variable phase shifter, a mixer, a variable low noise matching amplifier, analog-to-digital converter, a processor and a spectrum analyzer. A first low noise signal, created by the low noise source, is routed through the unit under test and variable amplifier to the mixer. A second low noise signal, also created by the low noise source, is routed through the variable phase shifter to the mixer. The mixer places the received signals in phase quadrature and outputs a measurement test signal which is routed through an analog-to-digital convertor to the processor and spectrum analyzer. The processor includes control links for adjusting the amplifier, low noise source and phase shifter to ensure that the signals received by the mixer are in phase quadrature.Type: GrantFiled: May 17, 1999Date of Patent: May 21, 2002Inventor: Eugene Rzyski
