These trigger events are time stamped with sub-nanosecond resolution using the time-to-digital converter (TDC) capabilities of the digitizer. Some useful applications include Time of Flight (ToF) measurements, as well as time measurements between digital signals used in semiconductor tests.
This program performs the following steps to measure the time between the separate trigger events on two digitizers with sub-nanosecond resolution:
Software
Application Software: LabVIEW Base Development System 8.2
Driver: NI-Scope
Language(s): LabVIEW
Hardware
Hardware Group: High-Speed Digitizers (Scopes)
Hardware Model: PCI-5105, PXI-5154, PCI-5122, PCI-5124, PCI-5142, PCI-5152, PCI-5153, PCI-5154, PXI-5105, PXI-5114, PXI-5122, PXI-5124, PXI-5142, PXI-5152, PXI-5153, PCI-5114
To determine the time resolution for triggers on your digitizer, please refer to the specifications manual of the device. Further information on topics such as Time Stamping and TDC can also be found in the Fundamentals section of the NI High-Speed Digitizers Help Manual.
