Selection reference · illustrative scenario
Clock roles in the application
Meters, storage controllers and energy gateways have different acquisition, control, communication and event-time goals. Identify the role of each reference.
Engineering selection review
Review sampling references, time records, wireless and industrial interfaces separately. Evaluate noise, board temperature and supply switching in representative hardware.
Procurement and documentation
Include acquisition/control chips and roles and time error and synchronization, plus the existing full code, sample and production quantities and delivery target. Discuss nominated international brands and domestic candidates separately, confirming parameters and documents by part.
Illustrative validation scenario
Test clock and logging behavior across supply, load and communication conditions. Equipment projects validate their own metering and system performance.
