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_3	RTSI line 3
NIFGEN_VAL_RTSI_4	RTSI line 4
NIFGEN_VAL_RTSI_5	RTSI line 5
NIFGEN_VAL_RTSI_6	RTSI line 6
NIFGEN_VAL_RTSI_7	RTSI line 7
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
NIFGEN_VAL_TTL4	PXI TRIG4 or VXI TTL4
NIFGEN_VAL_TTL5	PXI TRIG5 or VXI TTL5
NIFGEN_VAL_TTL6	PXI TRIG6 or VXI TTL6

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.
