| Note 1: The calibration approach is required to achieve this accuracy. The calibration takes 2 times of successful external synchronization to warm up. (The normal interval between each synchronization is 1 s for IRIG-B and 1 min for DCF77or CPU/CRA head). Note 2: The event number contained in one group varies within 1...16. It depends on how many channels get the events occurred within same sampling window (that is, 0.5 ms). | ||
