Instrument timing using synchronized clocks |
摘要 |
<p>An instrumentation system which provides relatively precise time correlation among obtained measurements without dependence on trigger signal timing. An instrumentation system according to the present teachings includes a set of instruments 20-24 each having a clock 40-44 and an event buffer 30-34 for periodically logging a data record. Each data record includes a set of measurement data and a time-stamp obtained from the corresponding clock 40-44. The instrumentation system includes mechanisms 'for maintaining a synchronized time in the clocks 40-44 and mechanisms for stopping the logging in the event buffers 30-34 in response to an event of interest. Once event logging is stopped, the data records in the event buffers 30-34 may be correlated using their time-stamps and a time-stamp associated with the event of interest.</p> |
