A waveform reconstruction system and method for using the same are disclosed. The system includes an RF down-converter that receives a signal and outputs a down-converted signal. A demodulator demodulates the down-converted signal to generate a recovered digital data stream. A pattern detector detects a predetermined pattern in the recovered digital data stream. A delay generator delays the down-converted signal and outputs a delayed copy thereof. A signal processing circuit combines the delayed copy with previously received delayed copies of the down-converted signal to reconstruct an averaged waveform from the plurality of delayed copies having the predetermined pattern.

Method for reconstructing the characteristics of transmitted CDMA waveforms

A hierarchical test executive system comprising and including Procedure, Test, Measurement and Datapoint levels. A Procedure is an ordered list of Tests; a Test is a group of Measurements in a Procedure that share the same test algorithm, and thus the same software code; a Measurement is a configuration or setup for a Test, and provides parameters to a Test; and a Datapoint is a subset of a Measurement containing additional parameters that select a result when one Measurement generates multiple results. When initiated, the test executive system presents a list of models and the user selects a model to be tested. The program then uploads the test software corresponding to the selected model and presents a list and descriptions of Procedures to the user. The user selects one of the Procedures, and the program retrieves the selected procedure from the test software and expands it into Tests, Measurements and Datapoints as determined by the Procedure. The test executive system then loops through the Tests, Measurements and Datapoints, generating the results and a corresponding data structure on the fly.

Method and apparatus for generating electronic test and data structure

Disclosed is a product that provides a test executive program for controlling tests on a device under test that is separate and distinct from the test executive system. The product may be embodied in a media storing instructions that direct a processing unit to 1) perform an electronic test on the device under test, 2) provide an interface for communicating with an external system that is distinct from the test executive program, and for permitting the test system to be operated by the external system, 3) communicate with the external system, and 4) in response to signals generated by the external system, operate the test system. Other test executive methods and apparatus are also disclosed.

Externally controllable electronic test program

An electronic test system with a multi-level tree structure for summarizing the results of the test. The levels of the tree correspond to the hierarchical levels in the execution of a test procedure. The highest level, or first level, represents the result for the whole test procedure. Level two represents the results of various tests. Level three represents the results of various measurements performed in a test, and level four represents the results for various datapoints for a given measurement. Preferably, each level in the tree structure is characterized by a graphical element. The graphical element provides the information on the status of the result at that level. In the tree structure, the results at a higher level are determined by summarizing the results at the adjacent sub-level.

Test executive system with tree structure for summarizing results

A test executive system that allows running of selected tests. A graphical user interface allows the user to run all tests, run marginal and failed tests, or to run only selected tests. When the 'run selected tests' option is selected, check boxes appear on a procedure tree. Selected Procedures, Tests, Measurements and Datapoints may then be selected by checking on a box and deselected by checking the box a second time. A check appears in selected boxes. The brightness of a checked box indicates how many lower level items are checked. The selected Procedures, Tests, Measurements and Datapoints can be saved and recalled.

Electronic test program with run selection

An electronic test system that distinguishes erroneous and marginal results. The test system includes a memory and an electronic processor for controlling the execution of the test, obtaining test results and generating test results. The test results include a determination of whether the condition of the test datapoints is pass, fail, error or marginal, where pass indicates that the DUT has met a specification, fail indicates that the DUT has not met the specification, error indicates that the test system or interface to the DUT has failed, and marginal indicates that the system is marginally within specification. The test results are displayed on a graphical user interface. The test system provides the ability to control the progress of the test system based on the results. For example, the system can be programmed to stop on erroneous results, marginal results, failed results, combinations of the forgoing, or stop after each measurement. When the system stops, a drop-down window appears explaining the reason for the stoppage.

Electronic test program that can distinguish results

An electronic test system having an object oriented hierarchical infrastructure including classes that allow a test developer or a test user to design a desired electronic test system. The class relationships define the function of the electronic test system. Classes include a procedure class, a test class, a measurement class, a datapoint class, a parameter class, a DUT class, a test system class, a specification class, a run procedure class, a result class, a plug-in class, an exec class, a model class, a device class, a test system device class, a user menu item class, an application class, and a state class. These classes are implemented in a hierarchical structure in which a datapoint is a subset of a measurement, a measurement is a configuration for a test, a test is a group of measurements that share the same test algorithm, and a procedure is an ordered list of tests to be run, and includes a list of measurements and datapoints.

Electronic test system and method

An electronic test system with a progress window that enables the user to observe in one glance the progress and status of a test. The progress window is preferably comprised of graphical elements representing test results grouped along a progress axis representing the length of the test procedure. Each graphical element is preferably displayed as a bar, with the length of the bar perpendicular to the progress axis representing the value of the result. The specifications limits are represented by lines parallel to the progress axis. A line above the progress axis represents the upper specification limit and a line below the progress axis represents the lower specification limit. The bars are color coded to display the pass, fail and marginal status of the test.

Test executive system with progress window

A test executive system for controlling a test upon a device under test that is distinct and separate from said test executive system. The test executive system provides interactive dialog boxes in the following manner. A signal that an event in a testing procedure occurs is received. A file storing testing information is retrieved responsive to the signal. The testing information includes directions for the user to perform an action required to continue the test. The test executive system includes a web browser and the test information may comprise a web page. The testing information is displayed along with at least one input option. An input is then received from the user. The input is then processed responsive to receiving said input.

Electronic test program with test triggered interactive displays

An electronic test system with a test results view filter that enables the user to filter the test results of a test program according to their particular datapoint value status. The test results view filter is preferably comprised of graphical elements representing a plurality of test results view filter option buttons grouped together in said test results view filter. Each test result view filter option button is capable of filtering an entire test program for their respective datapoint value status and displaying said filtered datapoint value status. The test results view filter option buttons are selected from the group consisting of: all datapoint value status, failed datapoint value status, marginal datapoint value status, and selected datapoint value status.

Electronic test system with test results view filter

A microphone power supply for use with precision microphones having an attached pre-amplifier, connects to an analyzer with a coaxial cable and is powered by an ICP current source in the analyzer. The power supply provides a polarization voltage and a pre-amplifier power voltage to a microphone and pre-amplifier assembly. The power supply receives an AC audio signal produced by the microphone, buffers the AC signal, and provides the AC signal to the analyzer through the coaxial cable.
