Example line for 1 of 4 channels. (Line Drawing, Not to Scale):
Input Pulse edges (begin/end) set rising/falling tags bits.
____~~~~~~_________________________________ Input Pulse, Gate cycle begins
__________________~________________________ Delayed Rise Edge 'RE' Tag Bit
________________________~__________________ Delayed Fall Edge 'FE' Tag Bit
_____________ Tag Bits delayed by PipeLnDly
___| |_________________________ PipeLineDelay : 40nS
_____________________
_________________| |___ Capture Window: 60nS
___________________________________
___| |___ Gate Width : 100nS
If ‘RE’,’FE’ are outside Capture Window, data tag bit(s) will be missing.
CaptureWindow = GateWidth - PipeLineDelay
The default Pipe Line Delay is 40nS, default Gate Width is 100nS.
Setup CMD sequence for Pipeline Delay. CD, WT 1 0, WT 2 nn (10nS/cnt)
Setup CMD sequence for Gate Width. CD, WC 2 nn(10nS/cnt), WC 3 nn (2.56uS/cnt)
