Trigger enable input Sample Clauses

Trigger enable input. The AUX I/O connector can be configured as an AutoDMA trigger enable input signal. When enabled, a board will: • Wait for a rising or falling edge on the AUX I/O. • Wait for the number of trigger events necessary to capture the number of “records per buffer” in one AutoDMA segment specified at the start of the acquisition. • Repeat. The following code fragment configures the AUX I/O connector to acquire “records per buffer” records after it receives the rising edge of a TTL pulse connected on the AUX I/O connector. AlazarConfigureAuxIO( handle, // HANDLE -- board handle AUX_IN_TRIGGER_ENABLE, // U32 -- mode TRIGGER_SLOPE_POSITIVE // U32 -- parameter ); See section 2.4.2.8 “AutoDMA Scanning Applications” for more information.
