External Triggering on the PCI-5411.
Hardware: Signal Sources (AWG/FG/AO)>>Arbitrary Waveform and Function Generators>>PCI-5411
Problem: I have connected my external trigger to the EXT TRIG SMB connector on the front of my PCI-5411. How do I setup the external trigger in software to use that pin?
Solution:
If you want to use the EXT TRIGGER SMB connector on the PCI-5411 to use an external trigger you will have to specify the input string as NIFGEN_VAL_EXTERNAL. Below is a table that talks about the different options you can use for the trigger source
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
|

NIFGEN_VAL_RTSI_4
|
RTSI line 4
|
|
NIFGEN_VAL_RTSI_5
|
RTSI line 5
|
|
NIFGEN_VAL_RTSI_6

|
|
NIFGEN_VAL_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
|
For example, if you are using LabVIEW, you can create a string constant and wire it into the source input of the NIFGEN Configure Digital Edge Start Trigger.
