Patent number: 7768533Abstract: Programmable video generation and analyzer including a video asset for generating video signals having a primary composite video module for producing different types of a primary video signal and outputting the primary video signal via output channels, and a secondary video source module for producing a secondary composite video signal and outputting the secondary composite video signal via output channels. The secondary video source module produces the secondary composite video signal in an identical or different format than the primary video signal and different than the primary video signal. An NTSC/PAL converter is included, for example, as part of the secondary video source module, for generating video in NTSC format and PAL format. The NTSC/PAL converter accepts a stream of data from the primary composite video module and the secondary video source module and converts it into Composite Baseband Video, Y/Pr/Pb Component Video, Y/C Video (S_Video) or RGB Video.Type: GrantFiled: January 11, 2007Date of Patent: August 3, 2010Assignee: Advanced Testing Technologies, Inc.Inventors: William Biagiotti, David Howell

Patent number: 7624379Abstract: Electronic test system including hardware and software components and method of use of same which provide obsolescence mitigation. A set of governing rules for the system is defined and a test program test (TPS) is created to enable units to be tested. When a new component is introduced into the system, the change is detected and a new TPS is created. If the new TPS complies with the rules, testing using the new TPS is possible. If not, a determination is made as to whether any component of the TPS is obsolete and if not, the units can be tested using the new TPS without redefining the rules. When a component of the TPS is obsolete, the rules are reviewed to ascertain the effect of the removal of the component and optionally redefined to enable the new component to be used in combination with the remaining components.Type: GrantFiled: January 12, 2006Date of Patent: November 24, 2009Assignee: Advanced Testing Technologies, Inc.Inventor: Robert Spinner

Patent number: 7065466Abstract: System for testing attenuators by a flatness and standing wave ratio tests which includes a vector network analyzer (VNA) adapted to be coupled to a device under test (DUT) and which provides an input stimulus signal for the DUT and, when certain conditions are satisfied, receives an output signal from the DUT, and a calibration receiver adapted to be coupled to the DUT via a down-converter. When certain conditions are satisfied, the output signal from the DUT is sent to the calibration receiver (through the down-converter to be possibly modified thereby depending on the testing frequency). A signal generator provides a local oscillator (LO) signal for the down-converter. A control unit is connected to the instruments and embodies software which analyzes the testing conditions, i.e., the attenuator value being tested, and selects whether the network analyzer or the calibration receiver will measure the output signal from the DUT.Type: GrantFiled: January 29, 2004Date of Patent: June 20, 2006Assignee: Advanced Testing Technologies, Inc.Inventors: Jeffrey R.

Patent number: 6429796Abstract: A method for generating a waveform at a particular frequency in which a segment RAM depth is determined based on the relationship between the frequency and a variable clock value, a RAM based memory system is provided with waveform information, and the waveform is sequentially generated from a combination of the waveform information in the RAM based memory system from a first memory site to a memory site dependent on the segment RAM depth. The generated waveform is filtered to obtain only the waveform at the desired frequency. The RAM based memory system is provided with the waveform information by dividing each desired waveform into segments depending on the clock value and storing each segment in a respective memory site. An analog to digital converter may be evaluated by directing the desired waveform to the analog to digital converter. The generated waveform is tuned in the filter to a center frequency if it is a sinewave or a tuned squarewave.Type: GrantFiled: July 14, 2000Date of Patent: August 6, 2002Assignee: Advanced Testing Technologies Inc.Inventor: Robert M.
