niSync Read Last GPS or IRIG Timestamp (VI)

Installed With: NI-Sync

Returns the last GPS or IRIG timestamp received from the device.

Prior to calling this VI, you must reserve the source by calling niSync Enable GPS or IRIG Timestamping.

Note  

Use the pull-down menu to select an instance of this VI.

niSync Read Last GPS or IRIG Timestamp (GPS)

Returns two timestamps: one with the module's board time when the module received the GPS pulse per second signal, and the other with the time of the onboard GPS receiver. Use these two values to determine the delay between GPS and your module.

GPS time returns the time reported by the onboard GPS receiver.

itimestamp.gif

timestamp returns the board time at which the GPS pulse per second was received. This parameter returns 0 if the module never received a valid timestamp.

error out returns error conditions that occur after this node runs. This output provides standard error out functionality.

niSync Read Last GPS or IRIG Timestamp (IRIG)

Returns two timestamps: one with the board time when the module received the IRIG message, and one with the time encoded in the IRIG message. You can use these two values to determine the delay between the external IRIG source and your module or to test the stability of an external IRIG source against an external time reference.
