Multiple testing elements (26) are coupled to a bus (25) operated under the control of a graphically programmed computer (12). The computer (12) interrogates the bus (25) to identify the testing elements (26) coupled thereto. Icons (44) representing the testing elements (26) are displayed in an 'Equipment Shelf' window (40). The user drags icons (44') from this window (40) onto a 'Test Bench' window (42) and draws lines between I/O ports (4531 . . . 4431) on the icons (453 . . . 443) to graphically create a test circuit (54). The computer (12) generates bus commands to activate switches (28) to couple the testing elements (26) in the same manner as the graphical test circuit (54). Graphically set test ranges and parameters (472-494) are automatically sent to the testing elements (26) and test results (470) presented on the same computer display (16). The system (10) may be dynamically reconfigured for different tests without hand rewiring or loading of other test programs.

Integrated test and measurement means employing a graphical user

A communication system (10) includes a duplex digital communication node (14) and a half-duplex digital communication node (12). The half-duplex node (12) is configured to perform duplex testing. The half-duplex node (12) digitizes a test message (74), vocodes the test message (76), possibly encrypts the test message (78), FEC encodes the test message (80), assembles the test message into frames (82), and records the framed test message (84). During a duplex test mode of operation, the node (12) retrieves the test message (92) and transmits (90) it away from the node (12). During the duplex test mode, the node (12) also receives a signal, disassembles signal data from frames (114), FEC decodes the data (116), possibly decrypts the data (118), de-vocodes the data (120), and converts the resulting data stream into analog data (122).

Method and apparatus for communications testing using a recorded test

A tester for multiple types of radios has a first group of generic test elements common to all types of radios to be tested and second groups of test elements specific to each one of the multiple types of radios. Each of the second groups of test elements is mounted within a pluggable module for insertion into the tester where it couples to a common bus accessed by all of the other test elements and by the controlling computer. Each pluggable module contains a specific identifier which, when accessed by the controlling computer initiates a stored program which causes the computer, via the bus, to couple the various test elements into a configuration required to test the radio type associated with that identifier. The system is very compact and conveniently uses a lap top computer as the controlling element.

Modular radio test system and method

A method for providing detection of timing anomalies and eliminating falsely detected positions in a hyperbolic positioning system for a simulated battlefield system. The method selects a large number of transmitters for calculation of position of an object or person on the battle field. In addition, transmitters are selected which have a high dilution of precision factor.

Method for elimination of ambiguous solutions in a hyperbolic

A multi-mode position location method detects the location of movable detection devices which are attached to movable carriers in a simulated battlefield. The multi-mode position location method employs three modes of position location of the detection devices. The first mode is a Global Positioning System (GPS) differentially corrected position of the detection device. The second mode is a multilateration determined position of the detection device. The third mode is an autonomously determined GPS position of the detection device. The autonomously determined position is determined without any differential GPS corrections. The most accurately determined position of the detection device may be used for area weapons effects simulation and carrier tracking by transmitting the carrier's position to a master control station.
