The Precision Time Protocol ( PTP) is a protocol used to synchronize clocks throughout a computer network. The device is portable we can move it between locations to perform spot checks. Since GPS satellites actually use onboard Cesium and Rubidium atomic clocks as their timing source, the next best thing and a far cheaper option is to use a GPS receiver as a timing source. The MClock Lite is simple, but more than adequate for many digital audio setups: 10 word clock outputs (eight on rear, two on front); internal crystal clock (44.1 to 384kHz), or external word clock reference distribution unit (no jitter reduction or attempts to sync when running on external clock). A Stratum 1 Time Server is a network appliance that receives precise time from a hardware reference clock to provide a time resource to client computers. This makes the operating system's influence negligible, with the error rate in nanoseconds. This is an almost new product with accessories (see below). The operation of satellite navigations systems is based on the method of triangulation. Master Clocks take one or more precise timing reference signals as inputs, then convert and distribute those timing references to other devices to improve their accuracy. 4 SDA Serial Data Input. Atomic clocks use the oscillations of a particular atom as their "metronome". In this library, they are represented with objects of the duration class template, that couples a count representation and a period precision (e.g., ten milliseconds has ten as count representation and milliseconds as period precision ).
