Trigger enable output Clause Samples

Trigger enable output. The AUX I/O connector can be configured as an AutoDMA trigger enable output signal. When enabled, a board will: • Wait for softare to call AlazarForceTriggerEnable. • Output a TTL high signal on the AUX connector. • Wait for the number of trigger events necessary to capture the number of “records per buffer” in one AutoDMA buffer specified at the start of the acquisition. • Output a TLL low signal on the AUX connector. • Repeat. The following code fragment configures the AUX I/O connector to acquire “records per buffer” records after it receives a software trigger enable event. AlazarConfigureAuxIO( handle, // HANDLE -- board handle AUX_OUT_TRIGGER_ENABLE, // U32 -- mode 0 // U32 -- parameter (not used) ); See section 2.4.2.8 “AutoDMA Scanning Applications” for more information.
