Flying Probe Testing System & SCPI General Commands:
As a standardized command language for programmable instruments, SCPI general commands play a central role in the extended function testing of flying probes. It enables the test software to uniformly control different types of devices. SCPI commands have hierarchical and structured syntax characteristics, and the command set covers a wide range of functions from basic measurements to complex device configurations and burning operations, greatly reducing the difficulty for test engineers to master the underlying communication protocols of different devices and significantly improving the efficiency of test script writing and the scalability of the system.
Multi-device Collaborative Invocation Process:
Actual Application Case:
In the research and development process of a smart home appliance, the multi-device collaborative capability of the flying probe extended function testing system was fully utilized. In the circuit board design verification stage, the latest control program was first burned into the circuit board storage chip through the programmer. After the burning was completed, the programmable power supply was used to provide a stable working voltage for the circuit board to simulate the power supply scenario in actual use. Then, a multimeter was used to measure the current consumption of the key power pins of the circuit board to monitor the device power consumption. At the same time, the oscilloscope captured the waveform of the communication signal on the circuit board to analyze the signal transmission quality and ensure stable device communication. Throughout the testing process, the flying probe testing software automatically coordinated the collaborative work of the programmer, programmable power supply, multimeter, and oscilloscope according to the preset testing process, efficiently completing the functional testing and performance evaluation of the circuit board. Through this multi-device collaborative testing, problems such as excessive power supply ripple and communication signal interference in the circuit board design were timely discovered, providing accurate data basis for subsequent optimization and improvement, greatly shortening the product research and development cycle, and improving product quality.
Summary and Outlook:
By using software standard interfaces and SCPI general commands to call multimeters, oscilloscopes, programmable power supplies, and programmers, the flying probe extended function testing system has achieved a qualitative leap. This multi-device collaborative testing mode has greatly improved the flexibility, comprehensiveness, and precision of the testing system, deeply meeting the full-life-cycle testing requirements of electronic products from research and development to production to after-sales. With the continuous innovation of electronic technology, the flying probe testing system is expected to integrate more advanced testing equipment and technologies, such as high-precision spectrum analyzers and logic analyzers. At the same time, continuously optimize the standard interface and SCPI instruction system, improve the communication efficiency and collaborative precision between devices, realize the intelligent and automated upgrade of the testing process, and provide stronger support for the quality improvement and innovative development of electronic products.
