AlazarSetTriggerOperation examples Sample Clauses

AlazarSetTriggerOperation examples. The following code fragment configures a board to trigger when the signal connected to CH A rises above 0V. This example only uses trigger engine J. AlazarSetTriggerOperation( handle, // HANDLE -- board handle TRIG_ENGINE_OP_J, // U32 -- trigger operation TRIG_ENGINE_J, // U32 -- trigger engine id TRIG_CHAN_A, // U32 -- trigger source id TRIGGER_SLOPE_POSITIVE, // U32 -- trigger slope id 128, // U32 -- trigger level (128 = 0V) TRIG_ENGINE_K, // U32 -- trigger engine id TRIG_DISABLE, // U32 -- trigger source id for engine K TRIGGER_SLOPE_POSITIVE, // U32 -- trigger slope id 128 // U32 -- trigger level (0 – 255) ); The following code fragment configures a board to trigger when the signal connected to CH B rises above 500 mV, or falls below -200 mV, if CH B’s input range is ±1V. This example uses both trigger engine J and K. double inputRange_volts = 1.; // ±1V range double TriggerLevelJ_volts = .5; // +500 mV trigger level U32 triggerLevelJ = // U32 –- trigger level J (192) (U32)(128 + 127 * triggerLevelJ_volts / inputRange_volts); double triggerLevelK_volts = -.2; // -200 mV trigger level U32 triggerLevelK = // U32 – trigger level K (103) (U32)(128 + 127 * triggerLevelK_volts / inputRange_volts); AlazarSetTriggerOperation( handle, // HANDLE -- board handle TRIG_ENGINE_OP_J_OR_K, // U32 -- trigger operation TRIG_ENGINE_J, // U32 -- trigger engine id TRIG_CHAN_B, // U32 -- trigger source id TRIGGER_SLOPE_POSITIVE, // U32 -- trigger slope id triggerLevelJ, // U32 -- trigger level from 0 to 255 TRIG_ENGINE_K, // U32 -- trigger engine id TRIG_DISABLE, // U32 -- trigger source id for engine K TRIGGER_SLOPE_POSITIVE, // U32 -- trigger slope id triggerLevelK, // U32 -- trigger level from 0 to 255 );
