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)
