UltraFLEXplus system implements the Parallel Advanced Command Execution (PACE) architecture, which enhances test execution by delegating hardware commands to embedded processors and maintaining a pipeline for strict and predictable command execution. Pattern Oriented Programming (POP) burst in UltraFLEXplus system offers significant benefits in terms of test stability and optimization of test times, Test throughput increasing and test development time reducing and Flexibility and scalability enhancing. Compared to tests based on Visual Basic for Test (VBT) , test time reduction result brought by using single POP pattern is very limited. But when POP patterns are grouped together (burst mode) the test time optimized efficient will rise dramatically even to 40 to 60%. This paper will using really test cases with RF instruments ultrawave8G,ultrawave24G as well as UPAC300 to demonstrate the benefits POP-bursting brings to customer. Pure VBT testing, POP single pattern test and POP burst testing are compared.
