Realize a Frequency Stability Measurement System With PTP

The Precision Time synchronization Protocol (PTP) is designed to synchronize real-time clocks in the nodes of a distributed network system. In this paper, a frequency stability measurement system is examined. The key components of the proposed frequency stability measurement system are the receiver module and the printer port of a desktop computer. Sinusoidal signals generated by the measured oscillator are fed into the desktop computer via the self-designed receiver module and the printer port. From our results we find that the frequency stability measurement system can 1) obtain submicrosecond level time measurements and 2) accurately measure signals frequency stability.
