Title:
PROVIDING PRECISE TIMING CONTROL BETWEEN MULTIPLE STANDARDIZED TEST INSTRUMENTATION CHASSIS
Document Type and Number:
WIPO Patent Application WO2007015582
Kind Code:
B1
Abstract:
Precise timing control across multiple standardized chassis such as PXI is obtained by providing several control signals over PXI_LOCAL within each chassis, and by providing these control signals to other chassis. A Least Common Multiple (LCM) signal enables all clocks to have coincident clock edges occurring at every LCM edge. A start sequence allows all PXI expansion cards in the test system to start at the same time. A MATCH line enables pincard modules to check for expected DUT outputs and either continue execution of their local test programs or loop back and repeat a section of the local test program in accordance with the result of the DUT output check. An End Of Test (EOT) line enables any one pincard module to abruptly end the local test programs running in all other pincard modules if an error is detected by the local test program in the pincard module.
