Triggering:Trigger Source
Short Name: Trigger Source
This property controls which trigger source the signal generator uses.
After you call the niFgen Initiate Generation VI, the signal generator waits for the trigger you specify in this parameter. After it receives a trigger, the signal generator produces the number of cycles you specify in the Repeat Count property.
This is also the source for the trigger in the other trigger modes as specified by the Trigger Mode property.
Default Value: NIFGEN_VAL_IMMEDIATE
Defined Values:
| NIFGEN_VAL_IMMEDIATE | Immediate—The signal generator does not wait for a trigger of any kind. |
| NIFGEN_VAL_EXTERNAL | External—The signal generator waits for a trigger on the external trigger input. |
| NIFGEN_VAL_PFI_0 | PFI 0 |
| NIFGEN_VAL_PFI_1 | PFI 1 |
| NIFGEN_VAL_PFI_2 | PFI 2 |
| NIFGEN_VAL_PFI_3 | PFI 3 |
| NIFGEN_VAL_SOFTWARE_TRIG | Software Trigger—The signal generator waits until you call the niFgen Send Software Trigger VI. |
| NIFGEN_VAL_RTSI_0 | RTSI line 0 |
| NIFGEN_VAL_RTSI_1 | RTSI line 1 |
| NIFGEN_VAL_RTSI_2 | RTSI line 2 |

| NIFGEN_VAL_RTSI_5 | RTSI line 5 |
| NIFGEN_VAL_RTSI_6 | RTSI line 6 |

| NIFGEN_VAL_PXI_STAR | PXI Star |
| NIFGEN_VAL_TTL0 | PXI TRIG0 or VXI TTL0 |
| NIFGEN_VAL_TTL1 | PXI TRIG1 or VXI TTL1 |
| NIFGEN_VAL_TTL2 | PXI TRIG2 or VXI TTL2 |
| NIFGEN_VAL_TTL3 | PXI TRIG3 or VXI TTL3 |

Note You cannot change this property while the device is generating a waveform. If you want to change the device configuration, call the niFgen Abort Generation VI or wait for the generation to complete. |
