STZ-MS Series Phase Micro-leap Meter
STZ-MS Series Phase Micro-leap Meter
   The STZ-MS series phase micro-leap meter can connect to external atomic clocks' frequency and PPS signals, and perform high-resolution frequency and phase adjustments to enhance the timekeeping performance of atomic clocks (arrays). This device has an extremely low added stability degradation, meeting the frequency control requirements of all commercial atomic clocks currently in the field.
