Some radio clocks and related timekeeping gear have a pulse-per-second (PPS) signal that can be used to discipline the local clock oscillator to a high degree of precision, typically to the order less than 10ms in time and 0.01 parts-per-million (PPM) in frequency. The PPS signal can b...
This signal always select second output clock of IOPLL, e.g. outclk1, to be the one being phase shifted. Therefore, iopll_phased_clk signal is expected to connect to the second output clock of IOPLL. iopll_num_phase_shifts Output 3 Connect this signal to num_phase_shifts input port...
The invention provides a pulse per second (PPS) signal generating device for vehicle-mounted equipment. The PPS signal generating device comprises a hardware part and control software, wherein a constant-temperature crystal oscillator, an external error signal interface, calibrated equipment, and a ...
1,Based on Central China Power System Stability Control Device, the paper presents the receiving process of GPS timing signal, synchronized sampling from different areas under the control of GPS PPS ( pulse per second), the hardware interface and the access format for data exchange amo...
When the running situation of a rotating machine becomes abnormal or a part of it does not work well,it usually generates a periodic vibration signal or a periodic acoustic signal,which generally are periodic impulse signals with relatively strong noise. 这些信号通常是具有较强噪声的周期性脉冲信号...

The time-codes of the JJY signal are sent at a very low rate of 1 bps using pulse width modulation. We measured the delay of the decoded time-code sent from the JJY station on Mt.Otakadoya and received by a radio-controlled clock. The PPS (pulse per second) signal from the GPS ...

Many GPS receivers provide a 'one pulse per second' (1PPS) output signal, and some receivers are optimised for timing applications. This paper examines the 1PPS output pulse of three inexpensive GPS receivers: Trimble Lassen LP, Motorola M12+ Oncore and Sigtec MG5001. The Trimble and ...
