SyncSystem 4380A Products for Time Scale and Time Measurement Applications


The SyncSystem 4380A product family delivers high-performance, multi-channel measurement and coherent signal distribution with flexible plug-in modules, including 1/5/10 MHz, PPS, DC-IRIG, AM-IRIG and TOD, for precise phase and time interval applications. It references an internal rubidium oscillator, GNSS or external standards, such as cesium clocks and hydrogen masers, and can be manually steered by an external truth source. This 1U integrated system includes redundant hot-swappable power supplies for reliable operation in demanding time and frequency environments.

The SyncSystem 4380A Time Scale Edition adds all essential time scale system capabilities in a single, integrated package. It supports multi-channel clock measurements, advanced ensemble and time scale algorithms, GNSS common view for remote clock comparison, BIPM report generation and coherent output signals for autonomous, reliable time scale generation.

SyncSystem 4380A Input/Output Modules


The SyncSystem 4380A sets a new standard for flexibility and scalability with its advanced hot-swappable input/output modules. Designed for maximum versatility, these modules can be installed in any of the six available slots, allowing users to tailor the system to their specific application requirements. The SyncSystem 4380A modules can be mixed and matched in any combination, and each module can be added, removed or replaced without powering down the system’s continuous operation. The system’s intelligent auto-detection feature instantly recognizes and configures each module as it is installed, while the clearly labeled slot numbers make module identification and management straightforward.

The data sheet includes the full range of module options and technical specifications.
