IQD ICPT-1 Rubidium Oscillator

IQD ICPT-1 Rubidium Oscillator is a Rubidium clock designed using the Coherent Population Trap method, housed in a 9-pin through-hole metal case. ICPT-1 offers good short-term stability, tight tolerance, and low power consumption. The IQD ICPT-1 Rubidium Oscillator is ideal for synchronization of or as a reference for satellite and secure communications, navigation systems, and in financial, utility, security, and communications timing applications.
