Abstract: Methods, tools, systems and computer readable media for compliance testing instrumentation and/or software. Data from one or more analytical instruments and/or software is converted to a technology-neutral format, which is independent of instrument type, instrument model, instrument manufacturer and data type of the analytical instrument or software from which the data was outputted. Calculations are performed on the converted data to produce one or more outputs, and then selection is made from the one or more outputs to populate a final report, wherein the one or more outputs are standardized and are directly comparable to outputs resultant from carrying out the method on another set of one or more other analytical instruments and/or software, irrespective of manufacturer or model of the other analytical instruments and/or software.
Abstract: An apparatus and method for measuring displacement includes a light beam directed to an interferometer core that splits the light beam into first and second component beams. The first component beam is directed to a diffraction grating at approximately a Littrow angle. A diffraction is received by the interferometer core and is combined with the second component beam. The combination of the first and second component beams is measured to determine displacement of the diffraction grating.

Abstract: Staggered interleaved Nyquist regions associated with differing ADC clock rates (FCLK) avoids spectrum lost through disjoint guard bands at the end of or between adjacent Nyquist regions. The staggered interleaved Nyquist regions overlap by an amount at least as much as is consumed by the guard bands. Selectable anti-aliasing filters associated with each Nyquist region and its ADC clock rate are used to enforce the staggered Nyquist regions and their various guard bands. For example, and neglecting guard bands, an initial raw band of operation RB1 may be the First Nyquist region for a basic sampling frequency Fs. An adjacent raw band of operation RB2 that overlaps RB1 may be the Second Nyquist region for an alternate sampling frequency 2Fs/3. An adjacent raw band of operation RB3 that overlaps RB2 may be the Second Nyquist region for the basic sampling frequency Fs. These raw bands interleave and overlap: RB1: DC to Fs/2 1st Nyq. for FCLK = Fs RB2: (2/3)Fs ? to 2(2Fs/3)/2 = 2nd Nyq.

Abstract: A Method and Apparatus to Perform Surgical Reactive Jamming while Maintaining Simultaneous Tactical Communications is disclosed. The system provides an enhancement to surgical reactive jammers that combines near-real-time jamming capability with the additional feature of allowing tactical communications. The tactical communications transmissions are compressed and packetized such that they can be broken up and transmitted during the jamming system's look-through periods. This approach facilitates listening during these look-through periods (not only for EW emitters, but also for friendly communications signals). The system should allows for talk during these look-through periods (“talk-through” periods). Such a system is unique in that it can automatically calculate the best frequency for a surgical reactive jammer to use against enemy targets as well as providing a fully secure tactical communications link which is synchronized with other units in the field.
Abstract: Methods, systems and computer program products for performing multi-location execution of tests between or among multi-sided test components in a wireless environment are described. Multiple flows are initiated substantially simultaneously and concurrently executed. A graphical representation of a multi-flow test is created that permits synchronization of the flows among agents at multiple remote locations. The graphical representation is converted into a textual representation in an open communication standard format, and information regarding each flow involved in the test is ascertained. The flows are substantially simultaneously initiated and concurrently executed with synchronization and dynamic data exchange components.

Abstract: A wavelength tunable laser unit has a laser mode selection, and is adapted to provide a laser signal in accordance with one or more laser control parameters. For operating the laser unit, the laser signal is swept in a wavelength range, a laser operation signal indicative of the laser unit's operation during the sweep is received, and the laser operation signal is analyzed for detecting an indication of a mode hop occurred in the generated laser signals during the sweep. At least one correction value is determined based on the detected mode hop indication, and at least one of the one or more laser control parameters, applicable for a next wavelength sweep, is modified based on the determined at least one correction value.

Abstract: A coefficient indicating the relationship between a measurement voltage of voltage measuring unit and a voltage drop in a drain bias voltage due to drain current is determined based on an S parameter of a bias tee and an input impedance of the measuring unit. A voltage drop at the drain is determined from the coefficient. Based on the determined voltage drop, a drain bias voltage actually applied to the drain of an FET is determined. Also, a coefficient for converting the measurement voltage of the measuring unit into a drain current is determined based on an S parameter of a two-terminal-pair network of the bias tee and the input impedance of the voltage measuring unit. Based on the determined coefficient, a drain current actually flowing in the FET is determined.
