Abstract
A computer-based instrument system is provided for progammably configuring a variety of computer-based test instruments for performing a variety of tests and permitting high speed execution of tests through concurrent operation of individual test instruments. The instruments are implemented on circuit boards and mounted in a chassis including permanent backplane wiring interconnecting the instruments and a timing and triggering control unit. The backplane wiring includes a conventional computer bus for carrying instructions from a master controller to each instrument and lines for a common system clock signal, protocol signals, and trigger signals between selected instruments and the timing and triggering control unit for synchronizing the operation of the instruments when performing a test. The timing and triggering control unit is adapted to programmably control instrument triggering according to individual test requirements without modification of backplane wiring. The backplane wiring further includes a high speed data bus for rapidly transferring data between instruments in the course of a test.
