Dear Help, About the of the trigger The waveform of ① attached with the following source code was acquired. However, if you want to acquire at the trigger position like ②, what kind of setting should be done? I am using the SDK in C# double range1 = 50; double range2 = 5; double acHz = 3561; int bufferSize = 8192; int tgch = 0; double hysteresis = (double)(50.0 / 100.0); double timeout = 100; double tleve = 0; double position = bufferSize / 2.0 / acHz; FDwfAnalogInConfigure(hdwf, false, false); FDwfAnalogInAcquisitionModeSet(hdwf, 0); FDwfAnalogInFrequencySet(hdwf, acHz); FDwfAnalogInBufferSizeSet(hdwf, bufferSize); FDwfAnalogInChannelEnableSet(hdwf, 0, true); FDwfAnalogInChannelEnableSet(hdwf, 1, true); FDwfAnalogInChannelRangeSet(hdwf, 0, range1); FDwfAnalogInChannelRangeSet(hdwf, 1, range2); FDwfAnalogInTriggerAutoTimeoutSet(hdwf, timeout); FDwfAnalogInTriggerSourceSet(hdwf, 2); FDwfAnalogInTriggerTypeSet(hdwf, 0); FDwfAnalogInTriggerChannelSet(hdwf, tgch); FDwfAnalogInTriggerLevelSet(hdwf, tleve); FDwfAnalogInTriggerConditionSet(hdwf, 0); FDwfAnalogInTriggerHysteresisSet(hdwf, hysteresis); FDwfAnalogInTriggerPositionSet(hdwf, position); FDwfAnalogInConfigure(hdwf, false, true); OutPutWave.... do { FDwfAnalogInStatus(hdwf, true, ref sts); } while (sts != AnalogDiscovery.DwfState.DwfStateDone); thank you for the help,
