Industrial D10289 Frequency Reference

Avtron K342 Frequency Reference (D10289, 10289, O10289, SC) is a remote reference oscillator from Avtron designed for industrial timing and synchronization tasks. The K342 is described in distributor catalogs as a Remote Frequency Reference K342, signaling its function as a standalone reference module that feeds other instruments in a timing network. The model is identified by D10289, with cross-refs including 10289 and O10289. Some listings indicate it may be available as new old stock (NOS). As a frequency reference, it provides a stable clock signal used to synchronize connected equipment, making it suitable for laboratories, test benches, and control environments where multiple devices share a common timebase. In catalogs within the Avtron/Nidec product ecosystem, the K342 sits among remote reference options, offering compatibility with legacy instrumentation that expects a dedicated reference input.
