Functions listed alphabetically

AGE1439_EXTERNAL uses transitions on the signal applied to the BNC external trigger connector on the front panel.

AGE1439_EXTERNAL_ECL uses ECL level transitions on the signal applied to the BNC external trigger connector on the front panel.

AGE1439_EXTERNAL_ECL has the same constant value as the AGE1439_EXTERNAL constant in the E1439C. AGE1439_EXTERNAL is retained for backward compatibility.

AGE1439_EXTERNAL_TTL uses TTL level transitions on the signal applied to the BNC external trigger connector on the front panel.

AGE1439_EXTERNAL_TTL is supported on all E1439B, C and D modules, but it is not supported on early E1439A modules. A module with a serial number lower than US41140000 will result in the error AGE1439_TTL_TRIGGER_NOT_SUPPORTED.

AGE1439_USER disables the module from any event-driven trigger generation though it is still possible to force the module to trigger a measurement by pulling the Sync line once the module is in the trigger state. You may do this by calling the age1439_meas_start function, waiting for the module to reach the trigger state, then triggering the measurement by using age1439_meas_ control to pull the Sync line.

AGE1439_IMMEDIATE triggers a measurement immediately upon entering the trigger state.

In multi-module systems all modules should be use the same trigger type in order to have the same actual delay.

Return Value

AGE1439_SUCCESS indicates that a function was successful.

Values other than AGE1439_SUCCESS indicate an error condition or other important status condition. To determine the error message, pass the return value to “age1439_error_message” on page 102.
