Abstract: A method for installing and/or testing software for a build-to-order computer system includes reading a plurality of component descriptors from a computer readable file. At least one component descriptor describes a respective component of the computer system. A plurality of steps are retrieved from a database, at least one step being associated with a respective component descriptor. A step also includes a respective sequence number. The plurality of steps are sequenced in a predetermined order according to the sequence numbers to provide a step sequence. The step sequence includes commands for installing and/or testing software upon the computer system.

Abstract: A method for installing and/or testing software for a build-to-order computer system having a plurality of components includes a plurality of elements. The computer system has an associated step sequence. The step sequence includes a plurality of steps where each step includes at least one command and a step is associated with a respective component descriptor. A component descriptor corresponds to a respective component of the computer system. The method includes accessing a command within the step sequence; creating a file including a start of execution indication; executing the command; deleting the file including the start of execution indication when the command completes execution; and repeating the accessing, creating, executing and deleting for the plurality of steps.

Abstract: An apparatus for installing software onto a computer system includes a step table and a component table. The step table contains a set of software installation steps shared among different components of substantially all computer systems being manufactured. The component table contains a set of substantially all possible components that are included within computer systems being manufactured. The computer system corresponds to a family of computer systems and the apparatus further includes a family relation table, a family relation table and a family component relation table. The family relation table identifies the relationship between a set of software installation steps and each family of computer system being manufactured. The family component relation table identifies the relationship between the family of computer systems and the set of components.

Abstract: A method to verify that a test and measurement system continues to operate within a predetermined acceptable range with respect to a given calibrated state previously defined for that system without the need for conventional external reference components. In accordance with one embodiment, performance verification of a network analyzer used to perform electrical measurements is achieved by storing RF "thru" measurement data (an RF thru measurement trace of the system) at the time of calibration at the factory or later repair and/or recalibration at a field service site. In accordance with another embodiment, performance verification of a lightwave component analyzer, used to perform electrical, electro-optical, opto-electrical, and optical measurements, is achieved by storing RF and optical thru measurement data (both an RF thru measurement trace of the system and an optical thru measurement trace of the system) at the time of calibration at the factory or later repair and/or recalibration.

Abstract: A lightwave component analyzer including at least an internal optical receiver and preferably also including an internal optical source which are selectively connectable by switches configurable by means of an instrument controller for calibration and performance of electro-optical, opto-electrical, and optical measurements. Transmission measurements of E/O devices are corrected for source match errors, and transmission measurements of O/E devices are corrected for load match errors, in addition to frequency response and cross-talk error correction. Response and match error correction provides for improved measurements of test devices with an electrical port having an impedance different from that of the measurement system impedance.

Abstract: A lightwave component measurement system provides modulation measurements and the use of digital signal processing for the resolution of single or multiple optical reflections in optical fiber cable or in open beam at discontinuities attributable to changes in the effective index of refraction in an optical transmission medium. The lightwave component measurement system preferably incorporates a transform capability that converts data measured in the modulation frequency domain to the time or distance domain. The time-domain data are both stable and accurate, since they are calculated from highly-stable, highly-precise frequency-domain information. The time-domain transform capability in the lightwave component measurement system allows a reflection to be located to millimeters, and resolution of multiple discontinuities just centimeters apart.

Abstract: A lightwave component analyzer comprising at least an internal optical receiver and preferably also comprising an internal optical source which are selectively connectable by switches configurable by means of an internal or an external instrument controller for calibration and performance of electro-optical, opto-electrical, and optical measurements. The switches are arranged in a switch matrix. The configurable switch matrix is connected by the instrument controller in response to selection of a measurement by a user to facilitate calibration of, and test measurements of devices under test with, the lightwave component analyzer.

Abstract: A lightwave component analyzer and method for determining chromatic dispersion in single mode optical fiber. The lightwave component analyzer initially performs various measurements that are used in the determination of chromatic dispersion in single mode optical fiber. The lightwave component analyzer then computes a chromatic dispersion factor using the measured parameters, as well as additional parameters which are stored in the analyzer or entered by a user. Various expressions are described for computation of chromatic dispersion in single mode optical fiber.

Abstract: A method and apparatus for calibrating absolute and relative measurements of modulation and/or demodulation transfer characteristics of electro-optical and opto-electrical devices during setup of a lightwave component measurement system for characterizing performance of fiber optic systems and associated components. The lightwave component measurement system calibrated in accordance with the method of the invention provides the capability to measure the optical, electrical, and, especially, the electro-optical (E/O) and opto-electrical (O/E) components with specified measurement performance. In accordance with the calibration method of the invention, when the lightwave component measurement system is used to characterize an E/O or O/E device, an initial calibration reference is established based on the known characteristics of a lightwave source and lightwave receiver included in the lightwave component measurement system.

Abstract: A signal measurement system with softkey menus for guiding a user in selecting a desired test setup, including selection and connection of the device to be tested, as well as selecting calibration measurement and test measurement for the device. In response to a given softkey selection, the signal measurement system prompts the user with a set of displayed textual instructions and pictorial diagrams via a user interface to step the user through setup, calibration, and measurement processes. Preferably, a signal processing unit (or analyzer) included in the signal measurement system incorporates the user interface in firmware to guide and aid the user in connecting the device to be tested to the signal measurement system for the desired test, and leading the user through calibration and measurement processes. The analyzer preferably displays the softkey menus, instructional text displays, and pictorial block diagram displays on a cathode ray tube included in the analyzer to guide the user.
