Timing Frequency Series

SDI-36E

BDS-361E

The high performance rubidium atomic clock inside the clock device is used as a benchmark to generate low noise and highly stable 20MHz and 100MHz clock source signals by digital phase-locked frequency doubling based on orthogonal phase discrimination, and the two clock sources are allocated to 10 channels for output through the high isolation amplifier unit. You can view the operating status of the device through the indicators and network ports on the panel.

By adding a reference second pulse, the internal rubidium atomic clock can be calibrated, and the calibration status can be monitored through the network port. Because the frequency accuracy, medium and long term stability, drift rate and other frequency stability characteristics of the output 20MHz and 100MHz signals completely follow the internal rubidium atomic clock, the calibration of the clock source is realized.
