FAQ

Product-specific questions

Product-specific answers based on available technical information.

Can the PXI-4461 synchronize with PXI-4472 or PXI-4472B modules?

NI requires the standard PXI-4461 connector variant for this synchronization because it uses PXI Star Trigger. Hybrid-slot-compatible PXI-4461 modules lack that connection.

Can PFI0 export a trigger?

No. The PXI-4461 PFI line is input-only. NI describes using another suitable DAQ, DSA or timing module to export a routed trigger.
